摘　　要：以角度型和面积型的条件方程为例,说明数字化坐标为观测值的条件平差法,给出了闭合差的限差公式。讨论了数字化曲线的拉格朗插值及其参数方程的建立。This paper takes the conditional equation of the types of angle and area model as an example and explains the conditional adjust method when the digitizing coordinates are discussed as observations. The limited different formula of closure is given. Lagrange's interpolations of digitizing curve and establishment of parameter equation have been discussed. 
