文中将线性回归分析原理应用于由实测洪水资料计算马斯京干洪水演算方程中的两个参数Ｋ和Ｘ与试错法相比较，线性加归方法具有：计算过程可以程序化，由计算机完成；计算参数的准确性可以得到保证；消除了试错法中存在的人为因素对计算结果精度影响等优点．
In this paper, the principle of linear regression is applied to two parameters K and X calculated from the measured flood data in the Masking-Dry flood equation. Compared with the trial and error method, the linear regression method has the following features: the calculation process can be programmed and completed by the computer; The accuracy of the calculation parameters can be guaranteed; the advantages of the human factors in the trial and error method, such as the accuracy of the calculation result, are eliminated.
