防专校园太阳高度及升降方位的计算

Calculation of the height of the Sun and azimuth at ascending and falling in campus of the Disaster Prevention Technique

本文编制了计算某地理位置、某一天太阳的出升下降时刻和方位、室内需要照明的时间、能看到明亮星星的时间、能看到较暗星星的时间以及太阳最高高度和某一时刻太阳高度和方位的计算程序,并对程序进行了检验。以防灾技术高等专科学校1号教学楼3楼实训室的地理坐标(116°47.63IE,39°57.090′N)为例,计算了防灾技术高等专科学校2002年12月30日9点54分30秒的各参数值。

Program of calculate the azimuth and time of ascending and falling of the Sun, time of lighting needed in a day, time of bright star and dim star visible in a day, height of peak in a day, height and azimuth of the Sun in a certain time is coded and tested. The above parameters are given on 30 December 2002, in training center of Disaster Prevention Technique Department of the College of Disaster Prevention Technique U66°47.631 'E,39°57.090′N)as an example.
