6)equation of time时差

延伸阅读

时差时差time，equationof真太阳时与平太阳时的时刻之差。由于地球公转轨道为椭圆，地球绕太阳运动速度并非匀速，反映为真太阳在天球上的视运动速度不均匀，导致真太阳时不均匀。同时，地球轨道面和地球赤道面之间存在倾角，真太阳在黄道上不同点的时角变化率各不相同，也引起真太阳时的不均匀。这是产生时差的原因。时差的值在一年之中逐日变化，每年有4次为零，在4月16日、6月15日、9月1日和12月24日前后；4次为极值，在2月12日（负极大）、5月15日（正极小）、7月26日（负极小）和11月3日（正极大）前后。最大值达16分多。每天的时差数值载于《天文年历》中。
