The country managed to finish a preliminary assessment of its resources, start commercial development of two shale gas blocks, and carry out basic technological research for independent development of the gas. To encourage tire development of the sector, the country also issued a series of preferential policies. Two rounds of shale gas bidding were held successfuUy. However, shale gas development in China is still in an early stage. Challenges such as immature geoloy, ical theories, lack of key technologies and capital, and environmental issues are almost inevitable and need to be tackled before or duringthe exploration and development of shale gas in tlre country. Overall, shale gas has a bright future in China because of the country's urgent demand for cleaner energy and its current heavy reliance upon imported gas. The article suggests that China will be able to produce 40 bcm by 2020 and that a healthy development of shale gas will be good news for both chemical engineering and peak shaving reserves.展开更多

Although traditional chemical pesticides have quick effect, the disadvantages of high toxicity, strong pest resistance, and heavy pollution hinder the development of modern ecological agriculture, while physical means such as light trapping, sex pheromone method and biological control methods are more safe and lasting compared with chemical means. To provide reference and guidance for grub control and sweet potato production, the control methods against sweet potato grubs are comprehensively explored, and strategy and prospects of using biological technology to control pests are analyzed.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
