The meteorological parameters, such as solar radiation, temperature difference and wind velocity are boundary conditions in temperature effect analysis of structures.
在结构温度作用计算中需气象参数作为其边界条件，主要有日照辐射、气温日较差、风速这三个参数。
The base of EHTV calculation is analyzing the dynamic heat transfer to equivalent temperature difference Solar factor of windows, for the shading of windows it used external shading multiplier.
EHTV简化计算的基础是将这些动态热作用分解为等效温差、标准窗太阳辐射得热等参数，而且系统地提出外遮阳系数，简化了建筑遮阳对外窗太阳辐射得热的计算方法。
The sunshine duration is long, the temperature difference is big, the frost-free period is long, and the annual solar radiation amount is much, which is good for the growth of crops.
日照时间长，昼夜温差大，无霜期长，年太阳能辐射量大，对农作物生长十分有利。
