The time for the first call to each method is not included in the average, so initialization time isn't a factor in the results.

平均值中不包括每种方法第一次调用的时间，因此初始化时间不是结果中的一个因素。

Both of the observed radial velocity and separation being projective values, in order to determine the mass of binary galaxies the average projection factor may be derived by a statistical method.

双重星系或天体系统，用动力学方法测定其质量时，观测到的视向速度和距离间距，都是各自值的投影值，可用统计方法，求出一个关于它们的平均投影因子。
