摘　　要：平板太阳能集热器的效率方程和对应的效率曲线是判断集热器热性能的重要依据,前人分别用3个不同方程和3条不同曲线定量地描述了集热器效率。文章阐释了3条曲线的异同点,并提出将3条太阳热水器瞬时效率曲线统一起来的具体解决办法。Thermal properties of flat-plate solar collector are always judged by its efficiency equations and curves. As for this problem, there have been quite detailed derivation and conclusions. Scholars used three different equations and curves to describe the quantity of efficiency, however, there is rare unified analysis among the three. Therefore, many readers are apt to be confused with some relative concepts. As a result, this paper analyses the similarity and difference of the curves, and presents a practicable solution as well.
