The result indicates that the underestimation of the rainfall rate during heavy rain and the overestimation during light rain become small by ZDR method.

结果表明，从相对误差来看，双线偏振雷达使普通雷达的小雨高估、大雨低估的测量误差趋势减弱，它对小到中雨的测量结果优于普通雷达。

The relationship between ZH and ZDR, and KDP is not sensitive to the variations of DSD, which could be used in distinguishing the solid precipitation from rain.

同时给出的ZH与ZDR和KDP关系公式也基本不受雨滴谱变化的影响，它可以用于降水粒子相态的识别。

There is a linear relationship between differential reflectivity ZDR and the shape factor defined as the ratio of the horizontal scale to the vertical scale of a particle.

球锥扁椭球形冰粒的差反射率因子与粒子形状参数水平-垂直尺度比呈很好的线性正相关。
