摘　　要：依据对数十台太阳热水器热性能的测试数据 ,对平板式太阳热水器与真空管式太阳热水器的瞬时效率曲线进行了比较 ,并对它们之间的明显差异进行了定性分析 .结论为 ,不能用与平板式太阳热水器相同的格式和标准对真空管式太阳热水器进行非稳态效率的评价 .Instantaneous Efficiency of flat plat solar water heaters and evacuated tubular solar water heaters are compared on the basis of large experimental data about solar water heaters, and distinct differences between flat plat solar water heaters and evacuated tubular solar water heaters are analysied qualitativly. The results show that should not to appraised instantaneous efficiency of evacuated tubular solar water heaters by the appraisable standards and forms of flat plat solar water heaters.
