摘　　要：不同观测值联合平差的做法已实现,但在平差处理时,一般是确定其中一类观测值基本正确,另一类观测值可能存有较大的偏差,且方差分量估计也存在某些不合理性,据此很多文献均提出了调整权比的计算方法.针对这类计算方法,依据MATLAB语言编制出了应用程序.The combined adjustment of various observations has come into being. In the process of adjustment, the ordinary way is to determine that one type of observations is right, the other has a large deviation and the variance component estimation is often unreasonable. The three reference books expound the method of calculating the weight ratio adjustment. Refering to this method, this paper compiles a kind of application program based on the matlab language.
