详细地定量分析了降水估测中的ＺＲ关系和各类误差。由此可知，指数函数形式与幂函数形式的ＺＲ关系之间无明显差别；ＺＨ的参数因子ＡＨ不能太大；双线偏振雷达的测量误差导致的降雨强度估测误差在各类误差中最小；ＺＲ关系的不可拟合误差之标准差约为０．２１５，因而不容忽视。降雨强度的估测误差可认为呈一偏差逼近于０而标准差约为０．２６５的近正态分布，这对提高区域降水的估测精度尤为重要。
The quantitative analysis of ZR relationship and various kinds of errors in precipitation estimation are detailedly analyzed. It can be seen that there is no significant difference between the ZR relationship between the exponential function and the power function; the parameter parameter AH of ZH can not be too large; the error of rainfall intensity estimation caused by the measurement error of the bilinear polarization radar is not significant in all kinds of errors Minimum; ZR relationship of the unmeasurable error of the standard deviation of about 0.215, and therefore can not be ignored. The estimation error of rainfall intensity can be regarded as a near-normal distribution with a deviation approaching 0 and a standard deviation of about 0.265, which is especially important for improving the estimation accuracy of regional precipitation.
