| 摘 要： | 在附有限制条件的间接平差的应用中，若所列观测方程中实际用到的未知参数的个数少于所选参数的总数u时，就会出现法方程系数阵秩亏的问题。为了解决此问题，在理论公式推导的基础上，给出了一种新的解决方法，并结合算例进行了验证。

| Abstract: | In the application of indirect adjustment of observations with condition equations,while the number of parameters used in the observation equations is less than the total number of choiced parameters,the coefficient matrix of normal equation will be rank defect.Therefore,we give a new method to resolve this problem in the basic of theoretical approach with formula,and validated with an example. |
