摘　　要：采用蒙特-卡罗法对抛物柱面聚光器聚焦光斑能流密度进行计算,分析聚光器的表面形状误差、跟踪误差、接收器位置误差、接收器的遮挡、太阳形状、漫反射和聚光器边缘角对焦面能流分布的直接影响,为该面型聚光器的系统设计、安装和能流密度测量提供依据。The Monte-Carlo method was used for calculating the focal spot flux density distribution of parabolic-trough concentrators. The effects of the random surface error, tracking error, position error and shadow of the receiver, sun shape, diffuse reflection and various semi-opening angles cases on the flux distribution were analyzed. It is a base for design and installation of the parabolic-trough concentration system and measuring the flux density distribution on the receiver.
