摘要
在计算机优化适线法和图解适线法的基础上 ,提出了有约束加权适线法 .该法能根据资料精度、适线目的以及图解适线的结果 ,直接调整点据的权重 ,并在参数的约束范围内使频率曲线与经验点据拟合最佳 。
Based on a computer optimized fitting method and a computer graphic fitting method, a constrained and weighted fitting method for hydrologic frequency calculation is developed. According to data accuracy, fitting goal and graphic fitting result, this method can directly adjust the weights of point data, and efficiently fit the frequency curve and empirical point data among the parameter constrained domain.
