An explicit functional relation of the point position variance of angular resection with observation value was derived.
推导了测角后交点位方差与观测值的显函数关系式。
In the case of small angular displacement, the natural frequency of the corresponding damping-free linear system is obtained, which is consistent with the experimental observation.
在小角位移的情形下，可近似得到相应的无阻尼线性系统的固有频率，它与观测结果吻合。
