一、关于二至日、二分日正午太阳高度角在各纬度的分布图象面法。根据太阳高度角公式:Ⅱ=90°-φ+8,式中的φ是自变量,在二至日和二分日δ是个常量,H是一次函数,其图象在座标系中是一条直线,决不可能是折线。如下图。 1.夏至日(6月22日)各纬度正午太阳高度的图象EH_1K。H_1K是北回归线到北极点各纬度正午太阳高度的图象。在直线H_1K上任何一点的横标值即为地理纬度φ值,其纵标值即该纬度上夏至日正
I. About the two-day, two-day noon solar altitude angle at all latitudes of the distribution of image surface method. According to the formula of the solar elevation angle: II=90°-φ+8, where φ is an independent variable, δ is a constant on the two-day and two-division days, H is a linear function, and its image is a straight line in the coordinate system. It can never be a polyline. As shown below. 1. Summer solstice (June 22) Image of the height of the noon sun at each latitude EH_1K. H_1K is the image of the noon sun height at various latitudes from the Tropic of Cancer to the North Pole. The horizontal scale value at any point on the straight line H_1K is the geographic latitude φ value, and the vertical scale value is the summer solstice at this latitude.
