摘　　要：研制了一个新的小型垂直过冷云风洞及其测试系统,实现了风、温数据自动采集,风洞内含水量测量方便易行.实验测量了温度-5—-18℃、含水量0.5—3.0g/m^3范围内冰雪晶生长的习性、下落速度、线性尺度增长率等诸参数.A new vertical supercooled cloud tunnel and the measuring system had been developed . Air stream speed and temperature are sampled automatically . Liquid water content of supercooled fog in the cloud tunnel can be measured easily . The experimental results show ice (snow) crystal growth behaviour, falling velocity and dimension growth rate with different ambient parameters of LWC and temperature .
