In calculation, this method USES the same stiff matrix, and only to renew the load vectors, which means it will reflect the geometric nonlinear effect in the load vectors' iteration.
计算时该格式使用同一刚度矩阵，只需要不断更新荷载矢量，即在荷载矢量的迭代中反映几何非线性效应。

The geometric meaning of this method is then defined not only for measurement of spatial curvature, but also for inspection for some other spatial vectors.
该方法不仅可以用于空间曲率检测的标定工作，也可适用其他一些空间矢量的检测工作。

Using the quasi-birth-and-death process method, we derive the equilibrium condition of the system and the matrix-geometric solution of the steady-state probability vectors.
