6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Above Sea Level
Height above mean sea level is a measure of the vertical distance ( height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as '' orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called " metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying ob ...

Qinghai
Qinghai (; alternately romanized as Tsinghai, Ch'inghai), also known as Kokonor, is a landlocked province in the northwest of the People's Republic of China. It is the fourth largest province of China by area and has the third smallest population. Its capital and largest city is Xining. Qinghai borders Gansu on the northeast, Xinjiang on the northwest, Sichuan on the southeast and the Tibet Autonomous Region on the southwest. Qinghai province was established in 1928 during the period of the Republic of China, and until 1949 was ruled by Chinese Muslim warlords known as the Ma clique. The Chinese name "Qinghai" is after Qinghai Lake, the largest lake in China. The lake is known as Tso ngon in Tibetan, and as Kokonor Lake in English, derived from the Mongol Oirat name for Qinghai Lake. Both Tso ngon and Kokonor are names found in historic documents to describe the region.Gangchen Khishong, 2001. ''Tibet and Manchu: An Assessment of Tibet-Manchu Relations in Five Phas ...

Tibet Autonomous Region
The Tibet Autonomous Region or Xizang Autonomous Region, often shortened to Tibet or Xizang, is a province-level autonomous region of the People's Republic of China in Southwest China. It was overlayed on the traditional Tibetan regions of Ü-Tsang and Kham. It was formally established in 1965 to replace the Tibet Area, the former administrative division of the People's Republic of China (PRC) established after the annexation of Tibet. The establishment was about five years after the 1959 Tibetan uprising and the dismissal of the Kashag, and about 13 years after the original annexation. The current borders of the Tibet Autonomous Region were generally established in the 18th century and include about half of historic Tibet, or the ethno-cultural Tibet. The Tibet Autonomous Region spans over and is the second-largest province-level division of China by area, after Xinjiang. Due to its harsh and rugged terrain, it is sparsely populated at just over 3.6 million people wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoh Xil
Hoh Xil or Kekexili, ( Mongolian for "Blue Ridge", also Aqênganggyai for "Lord of Ten Thousand Mountains"), is an isolated region in the northeastern part of Qinghai-Tibet Plateau. On July 7, 2017, the Hoh Xil in Qinghai was listed among the World Heritage Sites as "the largest and highest plateau in the world". Geography The region covers 83,000 square kilometres at an average elevation of 4,800 metres above sea level, stretches in the east-west direction between the Tanggula and Kunlun mountain chains in the border areas of southwest China's Tibet Autonomous Region, northwest China's Qinghai Province and China's Xinjiang Uyghur Autonomous Region.

Kunlun Mountains
The Kunlun Mountains ( zh, s=昆仑山, t=崑崙山, p=Kūnlún Shān, ; ug, كۇئېنلۇن تاغ تىزمىسى / قۇرۇم تاغ تىزمىسى ) constitute one of the longest mountain chains in Asia, extending for more than . In the broadest sense, the chain forms the northern edge of the Tibetan Plateau south of the Tarim Basin. The exact definition of Kunlun Mountains varies over time. Older sources used Kunlun to mean the mountain belt that runs across the center of China, that is, Altyn Tagh along with the Qilian and Qin Mountains. Recent sources have the Kunlun range forming most of the south side of the Tarim Basin and then continuing east, south of the Altyn Tagh. Sima Qian (''Records of the Grand Historian'', scroll 123) says that Emperor Wu of Han sent men to find the source of the Yellow River and gave the name Kunlun to the mountains at its source. The name seems to have originated as a semi-mythical location in the classical Chinese text ''Classic of Moun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanggula
The Tanggula (Chinese: , p ''Tánggǔlāshān'', or , p ''Tánggǔlāshānmài''), Tangla, Tanglha, or Dangla Mountains ( Tibetan: , w ''Gdang La'', z ''Dang La'') are a mountain range in the central part of the Qinghai-Tibet Plateau in Tibet, China. Administratively, the range is in the Nagqu Prefecture of the Tibet Autonomous Region, with the central section extending into nearby Tanggula Town and the eastern section entering the Yushu Tibetan Autonomous Prefecture of Qinghai province. The Tanggula is the source of the Ulan Moron and Dangqu Rivers, the geographic headwaters of the Yangtze River. The range thus functions as a dividing range between the basin of the Yangtze in the north and the endorheic basins of north-eastern Tibet in the south. Overview The elevations of the main ridge average more than . The Yangtze River originates in this mountain range; Geladandong, high, located in Tanggula Town, is the tallest peak in the range.
