POM用在那些对润滑性、耐磨损性、刚性和尺寸稳定性要求比较严格的滑动和滚动的机械部件上，性能尤为优越，因此主要用于工业机械、汽车、电子电气、管件和灌溉用品等方面。中国pom市场增长迅速，2002年中国pom市场表观消费量为13.657万吨，1990～2002年pom市场表观消费量年均增长率为11.7%。预计2005年中国pom市场表观消费量为16.8万吨，2000～2005年pom市场表观消费量年均增长率将达到10.3%。到2010年，中国pom市场表观消费量将增加到19.7万吨，2005～2010年pom市场表观消费量年均增长率将达到3.2%。

Electricity from the desert

“Solar thermal power plants concentrate sunlight to produce high temperatures. In sunny regions, they are thus able to deliver large quantities of environment-friendly electricity from a renewable source,” explains Professor Robert Pitz-Paal, Director of the Institute of Solar Research at the German Aerospace Center (DLR). Concentrating solar power (CSP) is best suited to countries with high sun intensity. The Moroccan solar park is in a perfect location: in the area around Ouarzazate, solar radiation reaches an intensity of more than 2,500 kilowatt-hours (kWh) per square meter per year, one of the highest levels in the world.
