欧洲几家公司组成的小组正在研制两种激光器,可用以预报去年10月曾袭击英格兰东南部的那种风暴。激光器将放在绕地球轨道运行的卫星上,可检测未变成飓风之前的很大风流图。去年10月,欧洲空间局授予两个合同来发展这种激光器。由英国费兰提公司领导的一个协作组将发展二氧化碳激光器,另一公司集团将研制较短波长的激 A group of several European companies is developing two kinds of lasers to predict the kind of storm that hit southern England in October last year. The laser will be placed on orbiting satellites orbiting the Earth, detecting large winds before they become a hurricane. Last October, the European Space Agency awarded two contracts to develop the laser. A collaborative group led by Feilanthi, UK, will develop a carbon dioxide laser and another group of companies will develop a shorter-wavelength stimulus
