基本解释

The theoretically analyzed results of the illuminance distribution and brightness distribution of the interior surface were introduced for the new artificial sky hemisphere.
介绍笔者对全阴天空半球内表面照度和亮度分布的理论分析成果，为全阴天空半球的设计和改建提供理论依据；
During testing the daylight factor, traditional illuminance apparatus cannot get the daylight factor in the standard luminance of the overcast skies tested under different sky conditions.
目前在采光系数测定过程中，传统的测试方法不能在任何天空状况下确定标准全云天的室内测点采光系数。
This paper suggests a zenith luminance converting factor. By means of multiplying outdoor horizontal sky illuminance by this factor, the value of zenith luminance of the sky can be obtained.
本文建议了一种天顶亮度转换系数，它与室外无遮挡水平面上的天空散射光照度相乘，就能获得该天空类型的天顶亮度值。
