1.近来,对地球表面遥测的各种观点引起了极大注意。这些研究首先着重于揭示大气和海洋的污染源,预测海洋生物的产量或农作物收成。这些工作既有从飞机机舱和宇宙飞行器中实现被动方法的报导(参阅文献1～3),也有从地面装置或舰船上实现主动激光探测法的报导。把激光探测方法 1. Recently, great attention has been paid to various points of telemetry on the Earth’s surface. These studies first focus on revealing the sources of pollution in the atmosphere and oceans, and forecasting the production of marine organisms or crop yields. These efforts cover both passive methods from aircraft cabin and spacecraft (see References 1 to 3), as well as active laser detection from ground-based devices or ships. The laser detection method
