The model presented here only USES a digital elevation model (DEM) to compute direct solar radiation, time of irradiation and simply diffuse radiation.
本模型只需数字高程模型(dem)就可计算太阳直接辐射、日照时间和简化的散射辐射。
The extinction coefficient for diffuse and direct radiation is given by crop canopy architecture and solar position.
冠层对太阳漫射光的消光系数由作物株型确定，对直射光的消光系数由株型和太阳位置确定。
The method of simulation and separation of direct and diffuse solar radiation intensity is investigated.
探讨了太阳直射辐射强度、散射辐射强度的模拟及分离方法。
