在地形测量中，经常要用到双点后方交会的方法测定站点。有关双点后方交会的计算公式较多，但大多数公式推导较为复杂，计算不易掌握。从前方交会的基本公式出发，推导出形式简单、计算格式方便的双点后方交会公式，并给出计算实例。

When doing topographic survey ,researchers often use the double points resection method to point down the spot .There are many formulas of double points resection ,but most of them are quite complicate in deriva-tion .The paper introduces one simple resolution formula ,which starts with the forward intersection formula .The paper gives a detailed derivation of the formula and also calculating examples .
