摘　　要：在最小二乘意义下用 GNL法拟合了常见的四参数隐函数曲线 .将用循环搜索法确定初始值的未线性化参数数量由一个推广到两个 .并成功地以多个著名模型为例对此进行了验证 .The common curves of implicit function with 4 parameters are fitted in the meaning of least square by means of GNL method. The number of non-linearized parameters which initial values are determined by the method of cyclic search is double instead of single. And it is successful to test and verify this algorithm in several famous examples.
