含碘化银人工冰核检测问题

Detection about AgI-Type Seeding Agents of China

对中国人工影响天气中常用的几种碘化银催化剂的成核率做了比对,讨论了不同云室可能响应的主要冰核活化机制和混合云室检测误差来源,此外还给出了动态检测的尝试性结果。结果表明:碘化银类播云剂的检测除了应模拟冰核活化条件外,还应模拟冰核发生时的环境条件,当务之急是建造动态检测设备以取得更为接近实际的检测结果。

The ice nucleation effectiveness for several AgI-type seeding agents in common use in weather modification of China is compared. The ice nucleation mechanisms responsible for various cloud chambers and the error origins of the mixing cloud chamber are analysed. In addition, the measuring results of two seeding agents released with airflow are discussed also. The results show that the detection of AgI-type seeding agents should be regard to the environment as ice nuclei released besides the conditions of the ice nuclei activation should be better simulated by cloud chamber. It is pre-requisite to build testing equipment that could simulate the ventilation, and the test results would be more close to practice in this way.
