浅析“月上柳梢头”的数学模型

On "Liu Shao on the Head," the Mathematical Model

首先给出定义,说明出现"月上柳梢头,人约黄昏后"这一情景的自然条件,由公式T=0.8R+6,粗略计算农历十五月出时间,通过简单的几何论证,建立数学模型得函数关系式,计算得日落时间(地方太阳时).根据给出的黄昏的定义,推算日落时间,进而验证模型的合理性.

Firstly,the definition,description appears ＂ month on the willow,after Renyuehuanghun＂ This scenario natural conditions by the equation T=0.8R＋6,a rough calculation Lunar New Year 15 Moonrise,by simple geometric argument,a mathematical model was functional relationship,calculated sunset time（local solar time）.According to the definition given in the evening,the projected sunset times,and then verify that the model is reasonable.
