The cascade hydropower stations use water from the same river; in a sense, they form a cluster of hydropower stations which are linked together by the river stream. The dispatch and management of the cascade hydropower stations in a river basin differ from those of an ordinary single hydropower station. Without doubt, unified dispatch can facilitate the full harnessing of hydraulic resources and is in a better position to fulfill the objectives in the development of river basin. As a result, more and more river-basin cascade power stations around the world implement unif ied dispatching.展开更多

Shipping After entering into the 1990’s, the ship-building industry, badly affected by the long recession of the world shipping market, has been growing very slowly, while the competition has been a fierce one. From the shares enjoyed by the major shipping countries in the world, we can see that the first one is Japan which occupied 38%; South Korea came to the second,obtaining 15％; the third is Germany, being 8%. The shipbuilding industry in America is shrinking, owing to the high cost of production. Up to 1993,Japanese ship yards had still been in difficult situation, and many Japanese ship owners would rather order new ships from South Korea because the rising value of Japanese yen made it expensive to build in domestic yards. Nowadays, Japanese shipbuilding industry is exposed to the problem of scarce of labour force. The Korean shipbuilding industry,展开更多

The key auto parts are classified into 25 categories which are listed below:EFI system, spark plug, valve, tappet, piston & piston ring, bearing bush, turbo charger, diesel engine high-pressure pump, aluminium radiator, filters, diaphragm spring clutch, constant velocity universal joint, vacuum servo booster & master cylinder, non-asbestos friction materials, brake tube, brake hose, steering gear, steering ball joint, shock展开更多
