摘要：
This paper firstly educed some necessary formulae such as incidence angle and the vector of reflected sunlight and tracking tilt-angle via vector analysis. Then, shading and blocking distribution of analyzed mirror element was got by coordinates transform and ray-tracing method and annual average shading and blocking efficiency of LFR mirror field was analyzed by Statistic means. Finally, the effect of shading and blocking efficiency of LFR mirror field due to different linear absorber high, spacing between adjacent mirror element and width of mirror slat was analyzed and fitted calculating model of shading and blocking efficiency of LFR mirror field was presented.
