Nowadays , the national lightning detection networks have been set up in developed countries . the national important project - atmosphere automatic observation engineering is about to start in china . the first - term project of national lightning detection network , which consists of 90 lightning location stations in meteorological branch , will be finished at the end of 2003 地闪定位系统在几个发达国家已全国联网，我们国家重点工程项目“大气监测自动化系统工程”即将启动，其一期工程就是在2003年底将建立拥有90个闪电探测子站的全国闪电监测网。
To overcome this problem , not only the meteorological observation network has to be equipped with automated , higher precision , and more economical devices and instruments , but also a synthetic mobile observation system is required for filling in the data gaps between the surface and upper air sounding stations 为了克服这一问题，除了研制自动化程度高、测量精度高和性能价格比高的仪器设备来装备现有的定点大气观测网外，还应建设一些流动的大气监测系统，以获得常规大气观测台站空档间（如大洋、山区和荒漠等无人区）的天气现象和大气环境变化的信息。
The technology of sensor is the mainstay of modern information industry . gas sensor as a branch of modern sensors plays a crucial role in many fields such as food industry , atmosphere monitoring , vehicle exhaust and harmful gas detection and other aspects 传感器技术是现代信息产业的支柱,气体传感器作为传感器的重要分支,在现代生活中的应用领域越来越广泛,在食品工业、大气监测、汽车尾气快速实时测定、有毒气体检测、特定火灾现场的气氛监测、安全检查等方面发挥着越来越重要的作用。
