solar rotation

According to the solar altitudinal angle formula, earth rotation principle, ratio of building height and spacing meet minimum sunshine can be calculated by using solid geometry knowledge, technical data can be provided for solving construction daylighting entanglemant.

根据太阳高度角公式，地球自转原理，利用立体几何知识求算出楼房高度与最低日照要求下的间距比值，从而为解决建筑采光纠纷提供技术数据。

The influence of the tide raising force of nine planets line up on the solar differential rotation

行星的起潮力对太阳较差自转的影响&对1982年九星联珠对太阳较差自转角速度的估计

Scientists initially found it hard to take measurements of Haumea because of its extremely rapid rotation, faster than any other known body in the solar system-a day is only 3.9 hours long.

它的公转速度比太阳系中其他已知星体都要快，妊神星上的一天按照我们的计时标准只有3.9个小时，所以在开始的一段时间内，科学家们很难对它进行测量。

Another important characteristics of the active regions of proton flares is the rotation of the sunspot groups. The rotative direction of the sunspot groups have no connection with southern and northern hemisphere on solar disk.

黑子群的旋转是质子耀斑活动区的又一重要特征，黑子群的旋转方向与日面南、北半球无关。
