摘　　要：通过对二元函数乘积型逼近的研究，导出了乘积型最小二乘逼近的公式，讨论了乘积型参数估计的最优计算方法，给出了乘积型参数估计的计算公式，同时，根据这种方法建立了一个乘积型逼近的数学模型。The formula of the approximation of least squares of product pattern was deduced and the best calculating methods and formula for estimating product parameter was found out. Meanwhile,a mathematical model of approximation of product pattern was set up.
