散射

The impact of rain gauge measurements is to increase the precipitation estimated from satellite data. The main difference is in Taiwan and the southeastern China where satellite retrieval underestimates the precipitation rate during boreal spring and summer. For the different precipitation climate analyses, the Legates- Willmot rainfall climate analysis produces the largest annual mean regional rainfall.

微波放射的雨量反演比微波散射法所估计的雨量略高，增加了测站雨量计分析的综合估计，使得区域平均年降雨量比只用卫星资料的估计大，而主要的差异是源自於春、夏季以及台湾与大陆东南沿海地区，显示卫星资料低估区域的锋面降雨。

The triangular shape distributions would cause two-peaked energy distribution near the threshold energy, which must affect the group transfer matrix. The rectangular shape make the too large, that may lead to a negative neutron KERMA (kinetic energy release in materials) factor.
