| 摘 要： | 在旋转问题中，坐标系的选取至关重要，否则会因角速度测量不准而出现错误。旋转问题一级近似惯性坐标系，应该选取比被绕行物体高一级的天体引力场：（1）一般的旋转问题——固定在地球上的直角坐标系；（2）卫星绕地球旋转问题——日心一地心直角坐标系；（3）地球绕太阳旋转问题一艮河系心．日心直角坐标系。在天体物理学中，质量计算不准和旋转角速度测量不准导致黑洞猜想。

| Abstract: | Selection of the coordinate system is essential for rotate problem.Otherwise,mistakes may occur due to inaccurate measurement of angular speed. Approximate inertial coordinate system selections for rotate problems should be the gravitational field of a celestial body higher than the object being rotated：（1） the earth fixed Cartesian coordinate system for normal rotation problem;（2） heliocentric - geocentric Cartesian coordinate system for satellites orbiting the earth;（3） the Galaxy Heart - heliocentric Cartesian coordinates for Earth＇s rotation around the sun.In astrophysics,mass calculation error and angular velocity measurement error lead to a black hole conjecture. |
