除了计算机和通用外围设备外,在使用计算机进行设计时,还使用图形输入/输出设备。交互式图形系统对于CAD尤其重要。图形输入设备的一般用途是在计算机中显示平面上的点的坐标。常见的输入设备包括键盘,手写笔,触摸屏,操纵杆,跟踪球,鼠标,图形输入护罩和数字设备。
图形输出设备分为两个主要类别:软和打印。柔和的折磨计算机器设计了CAD/uploads/title/20240104/65965ed90828a.jpgBeb,用于各种图形显示,这些图形显示是机器与机器之间进行交互所必需的。普通图形显示三种类型:束映射,存储管映射和栅格扫描。为了使图像清晰,电子束必须不断重绘图形,因此称为更新显示,很容易擦除和更改适合交互式图形工具的图形。存储管会显示存储的图像而不进行更新,这使您可以显示大量数据且价格低廉。光栅扫描系统使您可以接收彩色图像,并且图像信息可以以更高的图像分辨率存储在所谓的帧缓冲区中。
以上便是我的一些见解和回答,可能不能如您所愿,但我真心希望能够对您有所帮助!不清楚的地方您还可以关注我的头条号“每日精彩科技”我将竭尽所知帮助您!

今天忘掉工作好好享受?
我会选择《远走高飞》这首歌
我一路看过千山和万水
我的脚踏遍天南和地北
日晒或是风吹,我都无所谓
路边那朵蔷薇 鲜红的纯粹
关掉手机管他谁是谁
天亮走到天黑 从不觉疲惫
黄昏中的堡垒 多颓废
如果迎着风就飞…
………………
闭上眼睛,歌曲无限循环,心早已放飞。……
10代cpu有几个寄存器?
1、数据寄存器 数据寄存器主要用来保存操作数和运算结果等信息,从而节省读取操作数所需占用总线和访问存储器的时间。 2、变址寄存器 32位CPU有2个32位通用寄存器ESI和EDI。其低16位对应先前CPU中的SI和DI,对低16位数据的存取,不影响高16位的数据。 寄存器ESI、EDI、SI和DI称为变址寄存器(Index Register),它们主要用于存放存储单元在段内的偏移量,用它们可实现多种存储器操作数的寻址方式,为以不同的地址形式访问存储单元提供方便。变址寄存器不可分割成8位寄存器。作为通用寄存器,也可存储算术逻辑运算的操作数和运算结果。它们可作一般的存储器指针使用。在字符串操作指令的执行过程中,对它们有特定的要求,而且还具有特殊的功能。 3、指针寄存器 32位CPU有2个32位通用寄存器EBP和ESP。其低16位对应先前CPU中的SBP和SP,对低16位数据的存取,不影响高16位的数据。 寄存器EBP、ESP、BP和SP称为指针寄存器(Pointer Register),主要用于存放堆栈内存储单元的偏移量,用它们可实现多种存储器操作数的寻址方式,为以不同的地址形式访问存储单元提供方便。指针寄存器不可分割成8位寄存器。作为通用寄存器,也可存储算术逻辑运算的操作数和运算结果。 它们主要用于访问堆栈内的存储单元,并且规定: BP为基指针(Base Pointer)寄存器,通过它减去一定的偏移值,来访问栈中的元素; SP为堆栈指针(Stack Pointer)寄存器,它始终指向栈顶。 说明:因栈的生长方向是从高地址向低地址生长,所以,进栈时,sp自减;出栈时,sp自增; 4、段寄存器 段寄存器是根据内存分段的管理模式而设置的。内存单元的物理地址由段寄存器的值和一个偏移量组合而成 的,这样可用两个较少位数的值组合成一个可访问较大物理空间的内存地址。 5、指令指针寄存器 32位CPU把指令指针扩展到32位,并记作EIP,EIP的低16位与先前CPU中的IP作用相同。 指令指针EIP、IP(Instruction Pointer)是存放下次将要执行的指令在代码段的偏移量。在具有预取指令功能的系统中,下次要执行的指令通常已被预取到指令队列中,除非发生转移情况。所以,在理解它们的功能时,不考虑存在指令队列的情况。 在实方式下,由于每个段的最大范围为64K,所以,EIP中的高16位肯定都为0,此时,相当于只用其低16位的IP来反映程序中指令的执行次序。 6、标志寄存器
工业以太网交换机有哪些功能特点?
工业以太网交换机的特点:
高性能以太网交换机技术来保证通信速度,采用的是IEEE802.3/802.3d/802.3u/802.3x接口标准和存储转换交换方式的输出方式,具有抑制广播风暴功能、端口链路告警功能;电源发生故障时故障信息用继电器输出进行报警,冗余24伏直流电源输入,工作温度在/uploads/title/20240104/65965ed90828a.jpg40度~75度工作温度,高强度外壳,防护等级达到IP30,工业级标准设计,10Base/uploads/title/20240104/65965ed90828a.jpgT/100Base/uploads/title/20240104/65965ed90828a.jpgTX自适应的以太网接口,MDI/MDI/uploads/title/20240104/65965ed90828a.jpgX,全双工/半双工自适应方式;安装方便,传输距离较大(相对而言),为了不受磁电的影响,具有电磁隔离和电磁保护的功能,它的这些特性决定工业以太网交换机可以用于工业控制自动化,道路交通控制自动化,楼宇自动控制系统,矿井自动控制系统,油田控制自动化,水电站控制自动化,电力系统控制自动化,机房监控系统等工业的应用。
工业以太网交换机在工业级设计一般在设计上满足:工业宽温设计,4级电磁兼容设计,冗余交直流电源输入,另外PCB板一般做“三防”处理。工业现场的环境比普通环境都要恶劣,至少在震动,湿气,温度上都要比普通环境恶劣,普通交换机在设计上没有抵御在工业环境中出现的各种情况的能力,普通交换机不能长时间工作在这种恶劣环境下,经常容易出现故障,更使维护成本上升,一般不建议在工业环境中使用商业交换机,为了能使交换机在这种恶劣环境中使用,故生产出能适应这种环境的交换机,工业级别的交换机的可靠性有电源故障,端口中断,可由继电器输出报警,冗余双直流电源输入,主动式电路保护,过压、欠压自动断路保护。
(1)功能:工业以太网交换机与工业网络通讯更加接近,比如各种现场总线的互通互联、设备的冗余以及设备要求的实时性。
(2)性能:主要体现在适用外界环境的参数不一样,工业环境除了特别恶劣的环境之外,还要求有EMI电磁兼容、温度、湿度、防尘等,特别是温度对工业网络设备的影响是最广泛的。

泰山谁知道英文介绍?
Mount Tai (Chinese: 泰山; pinyin: Tài Shān) is a mountain of historical and cultural significance located north of the city of Tai'an, in Shandong Province, China. The tallest peak is Jade Emperor Peak (simplified Chinese: 玉皇顶; traditional Chinese: 玉皇顶; pinyin: Yùhuáng Dīng), which is commonly reported as 1545 metres (5069 feet) tall[1], but is described by the Chinese government as 1532.7 metres (5028.5 feet)[2].Mount Tai is one of the "Five Sacred Mountains of Taoism". It is associated with sunrise, birth, and renewal, and is often regarded the foremost of the five. The temples on its slopes have been a destination for pilgrims for 3,000 years.Contents [hide]1 Location 2 History 3 Natural significance 4 Cultural significance 4.1 Dai Miao 4.2 Other Monuments 5 Infrastructure 6 Cultural references 7 Footnotes 8 External links [edit] Location Location within ChinaMount Tai is located just north of the city of Tai'an and to the south of the provincial capital Jinan. It extends from 150 to 1,545 metres above sea level and covers an area of 426 square kilometres at its base. The Jade Emperor Peak is located at 36° 16′N and 117° 6′E.[edit] HistoryTraces of human presence at Mount Tai date back to the Paleolithic period. Human settlement of the area can be proven from the neolithic period onwards. During this time, two cultures had emerged near the mountain, the Dawenkou to the north and Longshan to the south. In the Spring and Autumn Period, the mountain lay on the boundary between the competing States of Qi (north of the mountain) and Lu (south). In the ensuing Warring States Period, the State of Qi erected a 500 km/uploads/title/20240104/65965ed90828a.jpglong wall to protect itself against an invasion. Ruins of this wall are still present today. The name Tai'an of neighboring city is attributed to the saying "If Mount Tai is stable, so is the entire country" (both characters of Tai'an, 泰安, have independent meaning "peace").Religious worship of Mount Tai has a tradition of 3,000 years, it has been practiced from the time of the Shang to that of the Qing Dynasty. Over time, this worship evolved into an official imperial rite and Mount Tai became one of the principal places where the emperor would pay homage to Heaven (on the summit) and Earth (at the foot of the mountain) in the Fengshan Sacrifices (封禅). In 219 BC, Qin Shi Huang, the first Emperor of China, held a ceremony on the summit and proclaimed the unity of his empire in a famous inscription.Mount Tai has been a UNESCO World Heritage Site since 1987. In 2003, it attracted around 6 million visitors. A renovation project to be completed by late October 2005 aims at restoring cultural relics and the renovation of damaged buildings of cultural significance. Modern buildings which are inconsistent with the historic landscape are to be demolished. The total cost of the work is estimated at 15 million yuan (approximately US$1.8 million).[edit] Natural significance The Immortal Bridge, a natural landscapeMount Tai is a tilted fault/uploads/title/20240104/65965ed90828a.jpgblock mountain with height increasing from the north to the south. It is the oldest example of a paleo/uploads/title/20240104/65965ed90828a.jpgmetamorphic formation from the Cambrian Period in eastern China. Known as the Taishan Complex, this formation contains magnetized, metamorphic, and sedimentary rock as well as intrusions of other origins during the Archean Era. The uplift of the region started in the Proterozoic Era, by the end of the Proterozoic, it had become part of the continent.Besides the Jade Emperor Peak, other distinctive rock formations are the Heaven Candle Peak, the Fan Cliff, and the Rear Rock Basin.Mount Tai lies in the zone of oriental deciduous forest; about 80% of its area is covered with vegetation. The flora is known to comprise almost 1,000 species. Some of the trees in the area are very old and have cultural significance, such as the Han Dynasty Cypresses, which were planted by the Emperor Wu Di, the Tang Chinese Scholartree (about 2,100 years old), the Welcoming/uploads/title/20240104/65965ed90828a.jpgGuest Pine (500 years old) and the Fifth/uploads/title/20240104/65965ed90828a.jpgRank Pine, which was named originally by the Emperor Qin Shi Huang, but was replanted about 250 years ago.[edit] Cultural significance[edit] Dai Miao Dai Temple at Mount TaiThe Temple of the God of Mount Tai, known as the Dai Temple (Dai Miao) is the largest and most complete ancient building complex in the area. It is located at the foot of Mount Tai in the city of Tai'an and covers an area of 96,000 square meters. The temple was first built during the Qin Dynasty. Since the time of the Han Dynasty (206 BC /uploads/title/20240104/65965ed90828a.jpg 220 AD), its design has been a replica of the imperial palace, which makes it one out of three extant structures in China with the features of an imperial palace (the other two are the Forbidden City and the Confucius Temple in Qufu). The temple has five major halls and many small buildings. The centerpiece is the Palace of Heavenly Blessings (Tian Kuang), built in 1008, during the Northern Song Dynasty. The hall houses the mural painting "The God of Mount Tai Making a Journey", dated to the year 1009. The mural extends around the eastern, western and northern walls of the hall and is 3.3 metres high and 62 metres long. The theme of the painting is an inspection tour by the god. Next to the Palace of Heavenly Blessings stand the Yaocan Pavilion and the entrance archway as well as the Bronze Pavilion in the northeast corner. The Dai Temple is surrounded by the 2,100 year/uploads/title/20240104/65965ed90828a.jpgold Han Dynasty cypresses.Dong Yue Temple at Mount Tai[edit] Other MonumentsA flight of 7,200 total steps (including inner temple steps), with 6,293 Official Mountain Walkway Steps, lead up the East Peak of Mount Tai, along its course, there are 11 gates, 14 archways, 14 kiosks, and 4 pavilions.In total, there are 22 temples, 97 ruins, 819 stone tablets, and 1,018 cliff/uploads/title/20240104/65965ed90828a.jpgside and stone inscriptions located on Mount Tai. These include the Azure Cloud Temple dedicated to the daughter of the God of Mount Tai, the goddess Laomu and the Divine Rock Temple which features the Thousand/uploads/title/20240104/65965ed90828a.jpgBuddhas Hall with painted Arhat statues.[edit] Infrastructure Zeng Fu Temple at Mount Tai Stone inscriptions at Mount TaiVisitors can reach the peak of Mount Tai via a bus which terminates at the Midway Gate to Heaven, from there a cable car connects to the summit. Covering the same distance on foot takes from two and a half to six hours. The supplies for the many vendors along the road to the summit are carried up by porters either from the Midway Gate to Heaven or all the way up from the foot of the mountain.To climb up the mountain, one can take one of two routes. The more popular east route starts from Taishan Arch. On the way up the 7,200 stone steps, the climber first passes the Ten Thousand Immortals Tower (Wanxianlou), Arhat Cliff (Luohanya), and Palace to Goddess Dou Mu (Doumugong). The climbing from downtown up the mountain can take two and a half hours for the avid hiker to six hours for the leisure pace. To the northeast of the Palace to Goddess Dou Mu is Sutra Rock Valley in which the Buddhist Diamond Sutra was cut in characters measuring fifty centimeters across believed to be inscribed in the Northern Wei Dynasty. The west route, taken by fewer tourists, is more scenic, but has less culture heritage.[edit] Cultural referencesThe Chinese idiom "泰山北斗" (lit. Mount Tai & Big Dipper) is an epithet for a person of great distinction. According to an ancient quotation from Sima Qian, "Though death befalls all men alike, it may be weightier than Mount Tai or lighter than a feather." Mao Zedong referenced this quote in the 20th century: "To die for the people is weightier than Mount Tai, but to work for the fascists and die for the exploiters and oppressors is lighter than a feather". [1] Rage Against the Machine referenced this in the song "Year of tha Boomerang": "So I'm goin' out heavy sorta like Mount Tai". In 1987, Canadian progressive rock band Rush put out the Hold Your Fire album, containing the song "Tai Shan." The song was about drummer and lyricist Neil Peart's journey to Mount Tai. The Dai Miao is featured in Sid Meier's Civilization IV as a religious complex that can be built by a Great Prophet, thus establishing a holy shrine dedicated to Taoism in the Taoist holy city. Tai Shan is the name of the most popular beer of most of Western Shandong province. A popular Vietnamese saying Công cha như núi Thái Sơn, nghĩa mẹ như nước trong nguồn chảy ra, một lòng thờ mẹ kính cha, cho tròn chữ hiếu mới là đạo con, mentions Thai Son mountain which may be translated into Chinese as Tai Shan, and refers a father's work ethics to the grandeur of the mountain

除了计算机和通用外围设备外,在使用计算机进行设计时,还使用图形输入/输出设备。
交互式图形系统对于CAD尤其重要。图形输入设备的一般用途是在计算机中显示平面上的点的坐标。常见的输入设备包括键盘,手写笔,触摸屏,操纵杆,跟踪球,鼠标,图形输入护罩和数字设备。
图形输出设备分为两个主要类别:软和打印。
柔和的折磨计算机器设计了CAD/uploads/title/20240104/65965ed90828a.jpgBeb,用于各种图形显示,这些图形显示是机器与机器之间进行交互所必需的。普通图形显示三种类型:束映射,存储管映射和栅格扫描。为了使图像清晰,电子束必须不断重绘图形,因此称为更新显示,很容易擦除和更改适合交互式图形工具的图形。存储管会显示存储的图像而不进行更新,这使您可以显示大量数据且价格低廉。光栅扫描系统使您可以接收彩色图像,并且图像信息可以以更高的图像分辨率存储在所谓的帧缓冲区中。

今天忘掉工作好好享受?
我会选择《远走高飞》这首歌
我一路看过千山和万水
我的脚踏遍天南和地北
日晒或是风吹,我都无所谓
路边那朵蔷薇 鲜红的纯粹
关掉手机管他谁是谁
天亮走到天黑 从不觉疲惫
黄昏中的堡垒 多颓废
如果迎着风就飞…
………………
闭上眼睛,歌曲无限循环,心早已放飞。……
10代cpu有几个寄存器?
1、数据寄存器 数据寄存器主要用来保存操作数和运算结果等信息,从而节省读取操作数所需占用总线和访问存储器的时间。 2、变址寄存器 32位CPU有2个32位通用寄存器ESI和EDI。其低16位对应先前CPU中的SI和DI,对低16位数据的存取,不影响高16位的数据。 寄存器ESI、EDI、SI和DI称为变址寄存器(Index Register),它们主要用于存放存储单元在段内的偏移量,用它们可实现多种存储器操作数的寻址方式,为以不同的地址形式访问存储单元提供方便。变址寄存器不可分割成8位寄存器。作为通用寄存器,也可存储算术逻辑运算的操作数和运算结果。它们可作一般的存储器指针使用。在字符串操作指令的执行过程中,对它们有特定的要求,而且还具有特殊的功能。 3、指针寄存器 32位CPU有2个32位通用寄存器EBP和ESP。其低16位对应先前CPU中的SBP和SP,对低16位数据的存取,不影响高16位的数据。 寄存器EBP、ESP、BP和SP称为指针寄存器(Pointer Register),主要用于存放堆栈内存储单元的偏移量,用它们可实现多种存储器操作数的寻址方式,为以不同的地址形式访问存储单元提供方便。指针寄存器不可分割成8位寄存器。作为通用寄存器,也可存储算术逻辑运算的操作数和运算结果。 它们主要用于访问堆栈内的存储单元,并且规定: BP为基指针(Base Pointer)寄存器,通过它减去一定的偏移值,来访问栈中的元素; SP为堆栈指针(Stack Pointer)寄存器,它始终指向栈顶。 说明:因栈的生长方向是从高地址向低地址生长,所以,进栈时,sp自减;出栈时,sp自增; 4、段寄存器 段寄存器是根据内存分段的管理模式而设置的。内存单元的物理地址由段寄存器的值和一个偏移量组合而成 的,这样可用两个较少位数的值组合成一个可访问较大物理空间的内存地址。 5、指令指针寄存器 32位CPU把指令指针扩展到32位,并记作EIP,EIP的低16位与先前CPU中的IP作用相同。 指令指针EIP、IP(Instruction Pointer)是存放下次将要执行的指令在代码段的偏移量。在具有预取指令功能的系统中,下次要执行的指令通常已被预取到指令队列中,除非发生转移情况。所以,在理解它们的功能时,不考虑存在指令队列的情况。 在实方式下,由于每个段的最大范围为64K,所以,EIP中的高16位肯定都为0,此时,相当于只用其低16位的IP来反映程序中指令的执行次序。 6、标志寄存器
工业以太网交换机有哪些功能特点?
工业以太网交换机的特点:
高性能以太网交换机技术来保证通信速度,采用的是IEEE802.3/802.3d/802.3u/802.3x接口标准和存储转换交换方式的输出方式,具有抑制广播风暴功能、端口链路告警功能;电源发生故障时故障信息用继电器输出进行报警,冗余24伏直流电源输入,工作温度在/uploads/title/20240104/65965ed90828a.jpg40度~75度工作温度,高强度外壳,防护等级达到IP30,工业级标准设计,10Base/uploads/title/20240104/65965ed90828a.jpgT/100Base/uploads/title/20240104/65965ed90828a.jpgTX自适应的以太网接口,MDI/MDI/uploads/title/20240104/65965ed90828a.jpgX,全双工/半双工自适应方式;安装方便,传输距离较大(相对而言),为了不受磁电的影响,具有电磁隔离和电磁保护的功能,它的这些特性决定工业以太网交换机可以用于工业控制自动化,道路交通控制自动化,楼宇自动控制系统,矿井自动控制系统,油田控制自动化,水电站控制自动化,电力系统控制自动化,机房监控系统等工业的应用。
工业以太网交换机在工业级设计一般在设计上满足:工业宽温设计,4级电磁兼容设计,冗余交直流电源输入,另外PCB板一般做“三防”处理。工业现场的环境比普通环境都要恶劣,至少在震动,湿气,温度上都要比普通环境恶劣,普通交换机在设计上没有抵御在工业环境中出现的各种情况的能力,普通交换机不能长时间工作在这种恶劣环境下,经常容易出现故障,更使维护成本上升,一般不建议在工业环境中使用商业交换机,为了能使交换机在这种恶劣环境中使用,故生产出能适应这种环境的交换机,工业级别的交换机的可靠性有电源故障,端口中断,可由继电器输出报警,冗余双直流电源输入,主动式电路保护,过压、欠压自动断路保护。
(1)功能:工业以太网交换机与工业网络通讯更加接近,比如各种现场总线的互通互联、设备的冗余以及设备要求的实时性。
(2)性能:主要体现在适用外界环境的参数不一样,工业环境除了特别恶劣的环境之外,还要求有EMI电磁兼容、温度、湿度、防尘等,特别是温度对工业网络设备的影响是最广泛的。

泰山谁知道英文介绍?
Mount Tai (Chinese: 泰山; pinyin: Tài Shān) is a mountain of historical and cultural significance located north of the city of Tai'an, in Shandong Province, China. The tallest peak is Jade Emperor Peak (simplified Chinese: 玉皇顶; traditional Chinese: 玉皇顶; pinyin: Yùhuáng Dīng), which is commonly reported as 1545 metres (5069 feet) tall[1], but is described by the Chinese government as 1532.7 metres (5028.5 feet)[2].Mount Tai is one of the "Five Sacred Mountains of Taoism". It is associated with sunrise, birth, and renewal, and is often regarded the foremost of the five. The temples on its slopes have been a destination for pilgrims for 3,000 years.Contents [hide]1 Location 2 History 3 Natural significance 4 Cultural significance 4.1 Dai Miao 4.2 Other Monuments 5 Infrastructure 6 Cultural references 7 Footnotes 8 External links [edit] Location Location within ChinaMount Tai is located just north of the city of Tai'an and to the south of the provincial capital Jinan. It extends from 150 to 1,545 metres above sea level and covers an area of 426 square kilometres at its base. The Jade Emperor Peak is located at 36° 16′N and 117° 6′E.[edit] HistoryTraces of human presence at Mount Tai date back to the Paleolithic period. Human settlement of the area can be proven from the neolithic period onwards. During this time, two cultures had emerged near the mountain, the Dawenkou to the north and Longshan to the south. In the Spring and Autumn Period, the mountain lay on the boundary between the competing States of Qi (north of the mountain) and Lu (south). In the ensuing Warring States Period, the State of Qi erected a 500 km/uploads/title/20240104/65965ed90828a.jpglong wall to protect itself against an invasion. Ruins of this wall are still present today. The name Tai'an of neighboring city is attributed to the saying "If Mount Tai is stable, so is the entire country" (both characters of Tai'an, 泰安, have independent meaning "peace").Religious worship of Mount Tai has a tradition of 3,000 years, it has been practiced from the time of the Shang to that of the Qing Dynasty. Over time, this worship evolved into an official imperial rite and Mount Tai became one of the principal places where the emperor would pay homage to Heaven (on the summit) and Earth (at the foot of the mountain) in the Fengshan Sacrifices (封禅). In 219 BC, Qin Shi Huang, the first Emperor of China, held a ceremony on the summit and proclaimed the unity of his empire in a famous inscription.Mount Tai has been a UNESCO World Heritage Site since 1987. In 2003, it attracted around 6 million visitors. A renovation project to be completed by late October 2005 aims at restoring cultural relics and the renovation of damaged buildings of cultural significance. Modern buildings which are inconsistent with the historic landscape are to be demolished. The total cost of the work is estimated at 15 million yuan (approximately US$1.8 million).[edit] Natural significance The Immortal Bridge, a natural landscapeMount Tai is a tilted fault/uploads/title/20240104/65965ed90828a.jpgblock mountain with height increasing from the north to the south. It is the oldest example of a paleo/uploads/title/20240104/65965ed90828a.jpgmetamorphic formation from the Cambrian Period in eastern China. Known as the Taishan Complex, this formation contains magnetized, metamorphic, and sedimentary rock as well as intrusions of other origins during the Archean Era. The uplift of the region started in the Proterozoic Era, by the end of the Proterozoic, it had become part of the continent.Besides the Jade Emperor Peak, other distinctive rock formations are the Heaven Candle Peak, the Fan Cliff, and the Rear Rock Basin.Mount Tai lies in the zone of oriental deciduous forest; about 80% of its area is covered with vegetation. The flora is known to comprise almost 1,000 species. Some of the trees in the area are very old and have cultural significance, such as the Han Dynasty Cypresses, which were planted by the Emperor Wu Di, the Tang Chinese Scholartree (about 2,100 years old), the Welcoming/uploads/title/20240104/65965ed90828a.jpgGuest Pine (500 years old) and the Fifth/uploads/title/20240104/65965ed90828a.jpgRank Pine, which was named originally by the Emperor Qin Shi Huang, but was replanted about 250 years ago.[edit] Cultural significance[edit] Dai Miao Dai Temple at Mount TaiThe Temple of the God of Mount Tai, known as the Dai Temple (Dai Miao) is the largest and most complete ancient building complex in the area. It is located at the foot of Mount Tai in the city of Tai'an and covers an area of 96,000 square meters. The temple was first built during the Qin Dynasty. Since the time of the Han Dynasty (206 BC /uploads/title/20240104/65965ed90828a.jpg 220 AD), its design has been a replica of the imperial palace, which makes it one out of three extant structures in China with the features of an imperial palace (the other two are the Forbidden City and the Confucius Temple in Qufu). The temple has five major halls and many small buildings. The centerpiece is the Palace of Heavenly Blessings (Tian Kuang), built in 1008, during the Northern Song Dynasty. The hall houses the mural painting "The God of Mount Tai Making a Journey", dated to the year 1009. The mural extends around the eastern, western and northern walls of the hall and is 3.3 metres high and 62 metres long. The theme of the painting is an inspection tour by the god. Next to the Palace of Heavenly Blessings stand the Yaocan Pavilion and the entrance archway as well as the Bronze Pavilion in the northeast corner. The Dai Temple is surrounded by the 2,100 year/uploads/title/20240104/65965ed90828a.jpgold Han Dynasty cypresses.Dong Yue Temple at Mount Tai[edit] Other MonumentsA flight of 7,200 total steps (including inner temple steps), with 6,293 Official Mountain Walkway Steps, lead up the East Peak of Mount Tai, along its course, there are 11 gates, 14 archways, 14 kiosks, and 4 pavilions.In total, there are 22 temples, 97 ruins, 819 stone tablets, and 1,018 cliff/uploads/title/20240104/65965ed90828a.jpgside and stone inscriptions located on Mount Tai. These include the Azure Cloud Temple dedicated to the daughter of the God of Mount Tai, the goddess Laomu and the Divine Rock Temple which features the Thousand/uploads/title/20240104/65965ed90828a.jpgBuddhas Hall with painted Arhat statues.[edit] Infrastructure Zeng Fu Temple at Mount Tai Stone inscriptions at Mount TaiVisitors can reach the peak of Mount Tai via a bus which terminates at the Midway Gate to Heaven, from there a cable car connects to the summit. Covering the same distance on foot takes from two and a half to six hours. The supplies for the many vendors along the road to the summit are carried up by porters either from the Midway Gate to Heaven or all the way up from the foot of the mountain.To climb up the mountain, one can take one of two routes. The more popular east route starts from Taishan Arch. On the way up the 7,200 stone steps, the climber first passes the Ten Thousand Immortals Tower (Wanxianlou), Arhat Cliff (Luohanya), and Palace to Goddess Dou Mu (Doumugong). The climbing from downtown up the mountain can take two and a half hours for the avid hiker to six hours for the leisure pace. To the northeast of the Palace to Goddess Dou Mu is Sutra Rock Valley in which the Buddhist Diamond Sutra was cut in characters measuring fifty centimeters across believed to be inscribed in the Northern Wei Dynasty. The west route, taken by fewer tourists, is more scenic, but has less culture heritage.[edit] Cultural referencesThe Chinese idiom "泰山北斗" (lit. Mount Tai & Big Dipper) is an epithet for a person of great distinction. According to an ancient quotation from Sima Qian, "Though death befalls all men alike, it may be weightier than Mount Tai or lighter than a feather." Mao Zedong referenced this quote in the 20th century: "To die for the people is weightier than Mount Tai, but to work for the fascists and die for the exploiters and oppressors is lighter than a feather". [1] Rage Against the Machine referenced this in the song "Year of tha Boomerang": "So I'm goin' out heavy sorta like Mount Tai". In 1987, Canadian progressive rock band Rush put out the Hold Your Fire album, containing the song "Tai Shan." The song was about drummer and lyricist Neil Peart's journey to Mount Tai. The Dai Miao is featured in Sid Meier's Civilization IV as a religious complex that can be built by a Great Prophet, thus establishing a holy shrine dedicated to Taoism in the Taoist holy city. Tai Shan is the name of the most popular beer of most of Western Shandong province. A popular Vietnamese saying Công cha như núi Thái Sơn, nghĩa mẹ như nước trong nguồn chảy ra, một lòng thờ mẹ kính cha, cho tròn chữ hiếu mới là đạo con, mentions Thai Son mountain which may be translated into Chinese as Tai Shan, and refers a father's work ethics to the grandeur of the mountain
