| 摘 要： | 本文分析了平面控制网中包括不同类观测值时，由于权的不合理配置，而使平差结果产生不应有的误差的问题，并提出一种包含观测值权的确定的平差方法，即把各类观测值的精度也作为待定的数引入平差模型，然后用逐次趋近的解法，连同坐标未知数一起解出；最后通过方差检验，判断其迭代收敛，本文结合某大城市二等首级平面控制网（边角网）的实例进行计算，得到较为满意的结果。

| Abstract: | In the adjustment calculation of plane control networks, the problem of deformation in adjustment model due to the unreasonable collocation of weight for different kinds of obseryations is analysed. A new adjustment method including the determination of weights is given. It hag been examined by practical examples and the satisfactory conclusion is obtained. |
