小学《地理》第二部分第十小节,涉及到阳光的直射和斜射问题,这是理解气温日变化、年变化以及五带划分的基础。 阳光直射、斜射的实质是太阳入射角问题。太阳射出的可见光,与地平面形成的交角叫太阳入射角,它的性质是:同一时间内,在不同地点形成不同的交角;同一地点的不同时间形成的交角也不相同。
The tenth section of Part II of “Geography” of primary school deals with the issue of direct and oblique sunlight, which is the basis for understanding the diurnal variation of temperature, the annual change and the division of the five zones. The direct sunlight, oblique nature of the incident angle of the sun problem.

Its nature is: at the same time, different angles of intersection are formed at different places; and the angles of intersection formed at different times at the same place are also different.
