Salt In Chinese History
Salt in Chinese history including salt production and salt taxes played key roles in Economic history of China before 1912, economic development, and relations between state and society in China. The lure of salt profits led to technological innovation and Sprouts of capitalism, new ways to organize capital. Debate over government salt policies brought forth conflicting attitudes toward the nature of government, private wealth, the relation between the rich and the poor, while the administration of these salt policies was a practical test of a government's competence. Because salt is a necessity of life, the salt tax (sometimes called the Gabelle, salt gabelle, after the French term for a salt tax) had a broad base and could be set at a low rate and still be one of the most important Taxation in premodern China, sources of government revenue. In early times, governments gathered salt revenues by managing production and sales directly. After innovations in the mid-8th century, im ...

Sichuan
Sichuan is a province in Southwestern China, occupying the Sichuan Basin and Tibetan Plateau—between the Jinsha River to the west, the Daba Mountains to the north, and the Yunnan–Guizhou Plateau to the south. Its capital city is Chengdu, and its population stands at 83 million. Sichuan neighbors Qinghai and Gansu to the north, Shaanxi and Chongqing to the east, Guizhou and Yunnan to the south, and Tibet to the west. During antiquity, Sichuan was home to the kingdoms of Ba and Shu until their incorporation by the Qin. During the Three Kingdoms era (220–280), Liu Bei's state of Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Manchu conquest, but recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital of the Republic of China, and was heavily bombed. It was one of the last mainland areas captured ...

Natural Gas
Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. Methane is a colorless and odorless gas, and, after carbon dioxide, is the second-greatest greenhouse gas that contributes to global climate change. Because natural gas is odorless, a commercial odorizer, such as Methanethiol (mercaptan brand), that smells of hydrogen sulfide (rotten eggs) is added to the gas for the ready detection of gas leaks. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) are thermally decomposed under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other ...

Salt
In common usage, salt is a mineral composed primarily of sodium chloride (NaCl). When used in food, especially in granulated form, it is more formally called table salt. In the form of a natural crystalline mineral, salt is also known as rock salt or halite. Salt is essential for life in general (being the source of the essential dietary minerals sodium and chlorine), and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food. Salting, brining, and pickling are ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt works in China dates to approximately the same period. Salt was prized by the ancient Hebrews, Greeks, Romans, Byzantines, Hittites, Egyptians, and Indians. Salt became a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bamboo
Bamboos are a diverse group of mostly evergreen perennial plant, perennial flowering plants making up the subfamily (biology), subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family, in the case of ''Dendrocalamus sinicus'' having individual stalks (Culm (botany), culms) reaching a length of , up to in thickness and a weight of up to . The internodes of bamboos can also be of great length. ''Kinabaluchloa, Kinabaluchloa wrayi'' has internodes up to in length. and ''Arthrostylidium schomburgkii'' has internodes up to in length, exceeded in length only by Cyperus papyrus, papyrus. By contrast, the stalks of the tiny bamboo Raddiella, ''Raddiella vanessiae'' of the savannas of French Guiana measure only in length by about in width.

Casing (borehole)
Casing is a large diameter Pipe (fluid conveyance), pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream. The lower portion (and sometimes the entirety) is typically held in place with cement. Deeper strings usually are not cemented all the way to the surface, so the weight of the pipe must be partially supported by a casing hanger in the wellhead. Casing that is cemented in place aids the drilling process in several ways: * Prevents contamination of fresh water well zones. * Prevents unstable upper formations from caving in and sticking the drill string or forming large caverns. * Provides a strong upper foundation to allow use of high-density drilling fluid to continue drilling deeper. * Isolates various zones, which may have different pressures or fluids, in the drilled formations from one another. * Seal ...

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

The dominant international standard for Standard Chinese, Standard Mandarin since about 1982 has been Pinyin, Hanyu Pinyin, invented by a group of Chinese linguists, including Zhou Youguang, in the 1950s. Other well-known systems include Wade–Giles (Beijing Mandarin) and Yale romanization (Yale romanization of Mandarin, Beijing Mandarin and Yale romanization of Cantonese, Cantonese). There are many uses for Chinese romanization. Most broadly, it is used to provide a useful way for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
District (China)
The term ''district'', in the context of China, is used to refer to several unrelated political divisions in both ancient and modern China. In the modern context, district ( zh, s=区, labels=no), formally city-governed district, city-controlled district, or municipal district ( zh, s=市辖区, links=no, labels=no), are subdivisions of a Direct-administered municipality, municipality or a prefecture-level city. The rank of a district derives from the rank of its city. Districts of a municipality are prefectures of China, prefecture-level; districts of a sub-provincial division, sub-provincial city are sub-prefecture-level; and districts of a prefecture-level city are counties of China, county-level. The term was also formerly used to refer to obsolete District (China)#County-controlled districts (obsolete), county-controlled districts (also known as district public office).
