摘　　要：从数值计算的角度,通过理论推导可证明逆向验证法数学本质上是一种迭代法,通过实验可以检验其收敛性。由于利用逆向验证法得到的实验结果可能产生较大的误差,采用最小二乘法进行多点验证,即对公认值附近的多个初始值分别应用验证法进行计算并比较各个结果的最小二乘偏差,最终可得到可靠的数据处理结果。From the numerical computation perspective,the reverse verification method is theoretically an iterative method,and experiments can test its convergence.Given that experimental results from the reverse verification method may have large errors,the least squares method is used for multi-point verification.This involves calculating multiple initial values near the accepted value using the verification method and comparing the least squares deviations to obtain reliable data processing results.
