摘　　要：介绍了液态CO2的催化原理和催化技术,并根据催化后的雷达回波强度和雨量变化,分析了利用液态CO2催化技术实施人工增雨作业的效果。结果表明:对0^-5℃云层实施液态CO2作业后,影响区雷达回波增强,地面雨量增大。The effects of artificial precipitation stimulation using the liquid carbon dioxide catalysis technique are analyzed on the basis of the changes of the radar echo intensity and rainfall after introducing the liquid carbon dioxide catalysis principle and technique. Results show that the radar echo is enhanced and surface rainfall is increased in the influenced region by the liquid carbon dioxide catalysis technique after catalyzing the cloud layer of 0 -5 ℃.
