Sup'ung Dam
The Sup'ung Dam (), also referred to as the Shuifeng Dam and originally the Suihō Dam, is a gravity dam on the Yalu River between Kuandian Manchu Autonomous County, Liaoning Province in China and Sakju, Sakju County, North Pyongan, North Pyongan Province in North Korea. The dam was constructed by the Japanese between 1937 and 1943 in order to generate electricity and has been repaired and renovated several times throughout the years, mainly due to spillway damage from flooding. During the Korean War, Attack on the Sui-ho Dam, the dam was bombed by the United Nations Command (Korea), United Nations Command three separate times in order to disrupt power generation for the North Koreans. At the time of its completion, the dam was the largest in Asia, and power station was third-largest (after Hoover Dam and Wilson Dam) hydroelectric power station in the world. It is still the largest hydroelectric power station on the Yalu (Korean: Amnok) River. Power produced at the dam's main 630 M ...

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-29
The Boeing B-29 Superfortress is a retired American four-engined Propeller (aeronautics), propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the Boeing B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bomber, strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombings of Hiroshima and Nagasaki, atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a cabin pressurization, pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets.

Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict. After the end of World War II in 1945, Korea, which had been a Korea under Japanese rule, Japanese colony for 35 years, was Division of Korea, divided by the Soviet Union and the United States into two occupation zones at the 38th parallel north, 38th parallel, with plans for a future independent state. Due to political disagreements and influence from their backers, the zones formed their governments in 1948. North Korea was led by Kim Il S ...

Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force, electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change Alternating current, AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Irtysh River
The Irtysh is a river in Russia, China, and Kazakhstan. It is the chief tributary of the Ob and is also the longest tributary in the world. The river's source lies in the Mongolian Altai in Dzungaria (the northern part of Xinjiang, China) close to the border with Mongolia. The Irtysh's main tributaries include the Tobol, Demyanka and the Ishim. The Ob-Irtysh system forms a major drainage basin in Asia, encompassing most of Western Siberia and the Altai Mountains. Geography From its origins as the ''Kara-Irtysh'' (Black Irtysh) in the Mongolian Altay mountains in Xinjiang, China, the Irtysh flows northwest through Lake Zaysan in Kazakhstan, meeting the Ishim and Tobol rivers before merging with the Ob near Khanty-Mansiysk in western Siberia, Russia after . The name Black Irtysh (''Kara-Irtysh'' in Kazakh, or ''Cherny Irtysh'' in Russian) is applied by some authors, especially in Russia and Kazakhstan, to the upper course of the river, from its source entering Lake ...

When the Guangxu Emperor died without an heir, Empress Dowager Cixi picked his nephew Puyi, aged two, to succeed him as the Xuantong Emperor. Puyi's father, Zaifeng, Prince Chun, served as regent before Puyi was forced to abdicate as a result of the Xinhai Revolution, which ended two millennia of Chinese Empire, imperial rule and established the Republic of China (1912–1949), Republic of China. The Empress Dowager Longyu signed the Imperial Edict of the Abdication of the Qing Emperor on Puyi's behalf, and in return the royal family was offered the Articles of Favourable Treatment of the Great Qing Emperor after His Abdication, Articles of Favorable Treatment, which allowed him to retain his imperial title and continue to live in the Forbidden City.
