摘　　要：从四份ITU-R P.系列建议书中归纳出一种预测55 GHz以内微波雨衰的实用方法。简化了雨衰A0.01的计算步骤;计算了10 GHz以内的关于极化的系数;给出了部分重点地区的降雨率和0℃等温线高度的典型值。依据雨衰A0.01,发生频率可外推至99.999%-95%,微波频率可外推至55 GHz。计算逻辑清晰完整,易于实用化编程。An applied method of predicting rain attenuation of microwave up to 55 GHz is extracted from four ITU- R P. Series Recommendations. Calculating steps for rain attenuation A0. 01 are simplified; coefficients depending on polarization are computed,up to 10GHz; typical values of rainfall rate and 0℃ isotherm height in some significant regions are shown. Derived from A0. 01,extrapolation of occurrence frequency between 99. 999% - 95% could be available,as well as microwave frequency up to 55 GHz. Logic of calculation must be clear,complete,and easy for applied program.
