摘　　要：太阳辐射学中的地方时、地方真太阳时、时差、太阳赤纬、太阳时角等参数,是确定太阳辐照度模型的基础.针对上述参数不同,文献给出的不同计算方法,通过对其进行对比梳理,分析了不同计算方法之间的关系,并对各参数的物理单位进行了说明,并讨论了计算机模拟计算中对各参数计算单位的要求及转换,为太阳辐照模型的建立及数值模拟提供借鉴.Parameters of solar irradiance, such as local solar time, solar time, time difference, solar hour angle and more are basis of solar in＇adiance model determination. For the problem of these parameters calculation method is different in different literature, different calculation methods and relationship were discussed through comparative analysis. And the physical unit of each parameter was illustrated. Combining with calculation cases, requirements and conversion of physical unit were discussed when they are used in computer simulation. The conclusion provides a reference to solar irradiance model and numerical simulation.
