It proved that the primary rain attenuation influence factor is the minute rainfall rate of 0.01% time.
这同时也说明了，影响降雨衰减最主要的因素是0.01%时间的分钟降雨率。
From the contour map of minute rainfall rate, we can see that, the he heavy rainfall areas are coincident with serious rain attenuation areas.
由分钟降雨率等值线图和雨衰减等值曲线图，可以看出，降雨大的地方和雨衰减大的地方是一致的。
Rainfall has become one of the key factors which influence the transmission quality, because it has great attenuation to the electronic wave transmission of Ka band satellite communication system.
由于降雨对Ka波段卫星通信系统的电波传播的衰减较大，成为影响其传输质量的重要因素之一。
