What is the altitude of Nagqu Railway Station?
Question 1: What is the altitude of Nagqu County? I checked online for a long time, ranging from 1500 to 6500. I really can't be sure about the altitude of Nagqu County, such as Nagqu Station. Nagqu County belongs to the Northern Tibetan Plateau, and the average altitude of the entire county is about 4,500 meters. There are many mountains in the territory, but the slope is relatively gentle. Most of the mountains are in the shape of ***, and it belongs to the plateau and hilly terrain. Within the territory are plateau glacier-type snow-capped mountains that are covered with snow all year round and are inaccessible to people. The mountains are steep. The territory mainly includes the Sangdenkangsang Mountains in the southwest, the Namurea Mountains in the northwest, the Gonggawagama Mountains in the southeast, and the Seru Mountains and Kerea Mountains in the east. These peaks are all branch mountains or remnants of Nyenqentanglha Mountain Works. The highest peak in the territory is Sangdeng Kangsang Peak, with an altitude of about 6,500 meters. The main peak is 100 kilometers south of Nagqu Town. Gonggawa Peak, Laopu Gacheng Peak, Serulagan Peak, etc. are also snow-covered peaks all year round, with altitudes above 5,500 meters. Nagqu County is about 4,510 meters above sea level. Naqu Station is about 4520 meters above sea level.
Question 2: Has anyone been to Nagqu? Can you tell us about the train station? Nagqu Railway Station is the transfer station and supply station of the Qinghai-Tibet Railway. It is the highest railway station in the world. It is 322 kilometers away from *** Station and 820 kilometers away from Golmud Station on the Qinghai-Tibet Railway. The rich tourism resources within the territory also make it easy to visit in a short time.
Question 3: Trigonometric function question 1 y=cosβ=cos(α+β-α)
=cos(α+β)cosα+sin(α+β)sinα < /p>
Because α is an acute angle, so cosα=√(1-x2),
Because α and β are acute angles, so α+β∈(0,π), sin(α+ β)=4/5
So y=(-3/5)√(1-x2)+(4/5)x.
Because cos(α+β)=-3/53/5.
Therefore, the value range of It is the highest railway station in the world, and its rich tourism resources make it easy to visit in a short time. The train station is located in Omadige Village, Mendi Township, about two kilometers west of Nagqu, close to the Qinghai-Tibet Highway. The awning shape at the main entrance of the station reflects the image of the yurts and snow-capped mountains in the Qiangtang area.

Question 6: *** How many kilometers is the total length of the Qinghai-Tibet Railway? The total length of the Qinghai-Tibet Railway is 1956 kilometers
Introduction to the Qinghai-Tibet Railway
The total length of the Qinghai-Tibet Railway is 1956 kilometers, with 960 Kilometers of altitude are above 4,000 meters, of which 550 kilometers pass through the perennial frozen plateau zone. Its highest point is located at the Tanggula Mountain Pass, which is 5,072 meters above sea level and is snow-capped all year round. It is known as "the railway closest to the sky" and "the highest railway in the world". The construction of the Qinghai-Tibet Railway is a major strategic decision made by the Party Central Committee and the State Council at the beginning of the new century. It is one of the four national landmark projects in the "10th Five-Year Plan" and the first key project in the development of the western region.
The Qinghai-Tibet Railway starts from Xining City, Qinghai Province in the north, and ends at *** City, *** Autonomous Region, in the south, with a total length of approximately 1,956 kilometers, of which approximately 846 kilometers from Xining to Golmud was completed in 1984. The Golmud to *** section of the Qinghai-Tibet Railway, which is about to be built, will lead from the railway station of Golmud City, an important town in western Qinghai Province. After passing the Nanshan Pass, it will go to the hinterland of the Qinghai-Tibet Plateau, passing through Nachitai, Wudaoliang, Tuotuo River, Yanshiping, and over Tanggula Mountain enters the *** Autonomous Region, and then passes through Anduo, Nagqu, Damxiong, and Yangbajing to *** City, the capital of the *** Autonomous Region. The route is basically parallel to the Qinghai-Tibet Highway. The Qinghai-Tibet Railway passes through nature reserves such as Hoh Xil, Sanjiangyuan, and Qiangtang. It is also known as China's first "environmentally friendly railway" because of its unique environmentally friendly design and construction.
The Qinghai-Tibet Railway is the highest and longest plateau railway in the world today. The line passes through 960 kilometers of areas with an altitude above 4,000 meters. The highest point of the line over the Tanggula Mountain reaches 5,072 meters. It passes through 550 kilometers of continuous frozen soil for many years and 216 kilometers of the ninth-degree earthquake intensity zone. Along the route, there are high temperatures and anoxia, a fragile ecological environment, and active crustal movement. Building railways in such an area is highly exploratory and scientific, and the construction task is arduous. The Fenghuoshan Tunnel is the highest railway tunnel in the world; the Kunlun Mountain Tunnel, located at an altitude of 4,767 meters, has a total length of 1,686 meters and is known as the longest "frozen soil tunnel" in the world.
The construction of the Qinghai-Tibet Railway will end the history of no railways in the *** autonomous region, further improve the transportation conditions and investment environment on the Qinghai-Tibet Plateau, and promote *** resource development and rapid economic development. It will play an important role in strengthening the connection between the mainland and Taiwan, promoting cultural exchanges between Tibetans and other ethnic groups, enhancing ethnic unity, and benefiting people along the route.
