摘要
首先证明了加权最小范数平差一般解的一个重要性质，由此提出了利用附加的观测值来求解加积最小范数平差问题的方法，并证明了该法与利用一般解法等价性的充要条件。
General character for weighted least norm adjustment is proved in this paper first, thus a new solving adjustment problem method is given, which use pseudo-observations to solve weighted least norm adjustment. Then the sufficient and necessary conditions that this method is equivalence to general method are proved.
