提出使用新的途径──排序配对逼近法得出的双线偏振雷达降水估测ＺＲ关系参数因子比线性拟合法具有更好的代表性，且能体现提高区域降水估测精度，也能根据实际情形采用其它的误差类型作为获取及衡量参数的标准。对指数函数形式的ＺＲ关系来说，其参数因子Ａ０，ＡＨ及ＡＤＲ分别为０．０１６８４，０．０９６和－０．４１６５。该方法可以推广应用到多个变元及参数因子的复杂函数中。
Proposed a new approach ─ ─ ranked by the pairing approximation method derived from the two linear polarizer radar precipitation ZR parameters of the relationship between the better than the linear fitting method and can reflect the improvement of regional precipitation estimation accuracy, According to the actual situation to use other types of error as a measure to obtain and measure the standard. For the ZR relationship of the exponential function, the parameters A0, AH and ADR are 0.01684, 0.096 and -0.4165, respectively. This method can be extended to complex functions with multiple arguments and parameter factors.
