5 . 地球自西向东自转,造成了太阳每天东升西落运动.因这种现象是地球自转造成的人的视觉效果,所以天文学上把这种运动称为太阳周日视运动,其实质是地球自转的一种反映.研究太阳周日视运动轨迹对分析地球气候、计算当地日出日落时间、理解昼夜长短变化现象、设计建筑物日照时长等有重要意义.太阳周日视运动轨迹与太阳直射地球点有关,也与观测者当地的纬度有关.下图为春分(或秋分)日北纬
某地(如我国哈尔滨、松原、鸡西等地区)的太阳周日视运动轨迹图,
为当地观测者位置,圆平面
是观测者所在的地平面.直线
为天轴,其垂直于太阳视运动轨迹所在圆平面
,且与直线
在同一圆面上.两直线

.太阳早上
从正东方
点的地平面升起,中午
处于天空最高点
,傍晩

点处落入地平面.
与地平面
所成锐二面角的平面角为多少?
(2)若图上

太阳所在位置,此时阳光入射当地地平面的角度(即直线
与地平面
的夹角)为多少?
