摘　　要：根据槽式聚光器的几何光学特性,提出采用Origin软件计算槽式太阳能聚光器焦面能流密度分布的一种新方法。以抛物槽式聚光器的平面焦线为例详细介绍该计算方法的步骤,并将计算结果与实测结果进行对比,两者吻合较好,证明该计算方法的可行性和正确性。该计算方法函数关系较为简单明确,无需编程,计算量少,计算速度快,且适用于任意面型的槽式聚光器和线性接收器,可为槽式太阳能聚光系统的优化设计提供参考。According to the geometry optical properties of trough concentrator, a new method was proposed for calculating the flux density distribution on focal plane of trough solar concentrators using Origin software. Takes the focal line of parabolic trough solar concentrator （PTC） as an example, the steps of this calculation method was introduced in details, and the comparison of calculation results and measured results was made, good mach was obtained. The presented way was proved to be feasible and correct. The calculation method of this paper was simple and clear in the function relation, no need of programming, less calculation with computing speed fast. The way can be applied to arbitrary surface contour of concentrators and linear receivers, and can be used to offer useful references for design and optimization of the trough solar concentrating systems.
