摘　　要：给出了多因子可分离变量的非线性函数及4种求其数学模型的方法:综合法,逐次分离出因子法,逐次分离主因子与剩余因子综合分解残差相结合法以及逐次分离主因子与以剩余因子与残差距离为权线性分解残差法。最后,通过实例,对4种方法进行了比较分析。This paper shows four methods to reckon the mathematics model of multifactor separable variable non_linear function: synthetic method, seriatim separating factor method, seriatim separating main factor and remaining factors synthetical decomposing remnant difference combination method and the linear decomposing remnant difference method which seriatim separates main factor and taking the remaining factors and remnant difference distance as the certain rate of error. The four methods have been compared and analyzed in the applicalion.
