摘　　要：人工增雨效果的物理检验为评估人工影响天气的效果提供物理依据，因此越来越受到关注，文章根据2009年5月1日在河北张家口的一次积层混合云降水过程的飞机人工增雨作业探测资料，尝试了从不同高度上寻找对比区，来进行作业效果的物理检验。结果表明：利用反证法思路，发现温度在-10℃时，FSSP 100ER量程1（测量范围为2-47 μm）测量的云粒子中并不全是液相的，也有一定量冰相云粒子存在；而且不同高度粒子浓度急速增大的时刻与冰相云粒子陡增的时刻是趋于一致的，观测的实际结果基本符合冷云催化原理；降雨区域面积是扩大的，某种程度上讲，作业收到了一定的效果。The physical effects assessment provides physical basis for the artificial precipitation test, so it has got more and more attentions. Based on the aircraft operations information in Zhangjiakou on May 1, 2009, this paper tries to find the contrast area from different heights to conduct the physical examination of the operational effects. The results show that： Making use of reduction to absurdity, the FSSP （range one） measurements of droplets are found to be dominated by ice phase and liquid phase when it is -10℃, and the rapidly growing moment of concentration of the particles is relatively consistent with the rapidly growing of the ice phase cloud particles. The actual results of observation are basically in agreement with cold cloud catalytic principle, and the enlargement of rainfall area has proved that this aircraft cloud seeding is effective to a certain extent.
