冰珠-
雨滴可能先穿过暖空气层往下落，然后又接触到一团冷空气，于是每个雨滴都冻结成冰珠。
The rain drops may start downward through a layer of warm air and then strike a mass of cold air , where each raindrop freezes .

结果表明，冷壁面温度越低，水珠冻结时间越短，且冻结的冰珠越小；
The experimental results revealed that the lower the cold plate temperature is , the shorter the frozen time of water droplets , and the smaller the frozen water droplets .
