摘　　要：经过多项实验,论证了综合法坐标转换的可行性,并且从"逐点取最近点建模平面七参数坐标转换比较"和"逐点取最近点建模多项式坐标转换比较"2个方面检验和证明了转换的高精度和可靠性。After a series of test,we proved the High Feasibility of Sythesis Method Coordinate Transformation.We also examined and proved its high accuracy and high reliability by'compare by make 2D seven-parameter Model respectively by seek near points to transform' and'compare by make polynomial fitting model respectively by seek near points to transform'.
