太阳影长的参数模型研究

Study on Parameter Model of The Sun's Shadow Length

本文在实物长度、地理位置、时间已知的前提下,研究物体影长的变化规律。根据太阳的变化规律,通过中间变量太阳高度角、赤纬角和时角确立影长模型,运用单因素控制变量法分析影长关于各个参数的变化规律。从而为太阳影子定位技术等提供了理论依据。

In physical length, location, time, under the premise of known, studies the changing rule of the length of the shadow. According to the principle of trigonometric functions, intermediate variable Angle of the sun, the shadow length model established declination Angle and the Angle, and using the method of single factor control variable analysis shadow length about the change rule of each parameter. As the sun shadow positioning technology and provides a theoretical basis.
