By analyzing the model, we calculate the spherical distance in MATLAB programming method.

并且通过对模型的分析，采用MATLAB编程计算球面距离。

Through the solution, the star position angle can be found with so - called "star distance" (Short for the spherical distance between two stars)determined So as to have the fix solved.

用解球面三角形的方法，通过两天体的球面距离，求得星位角，从而求得船位的经纬度。

In other cases, a spherical model is used, and the primary distance calculation used is the great-circle distance (see Resources).

在其他情况下使用球面模型，所使用的主要距离计算为大圆弧长(参见参考资料)。

So, what we can do to actually get a probability instead of a probability density that we're talking about is to take the wave function squared, which we know is probability density, and multiply it by the volume of that very, very thin spherical shell that we're talking about at distance r.

我们能得到一个概率,而不是概率密度的方法,就是取波函数的平方，也就是概率密度，然后把它乘以一个在ｒ处的,非常非常小的,壳层体积。

a perfectly spherical shell dr at some distance, thickness, d r, dr we talk about it as 4 pi r squared d r, so we just multiply that by the probability density.

在某个地方的完美球型壳层,厚度，我们把它叫做4πr平方，我们仅仅是把它,乘以概率密度。
