| 摘 要： | 本文采用理论与试验结合的方法,就怎样得出正确数学模型,追索真正优化点进行了五个方面的探讨。分析得出:单纯用t检验,不能完全反映各参数对指标的影响程度;回归方程的有效范围根据试验条件的不同,绕理论值上下波动;回归模型的理论检验合格,不一定代表模型与实际拟合得很好;可以采用试验追索法,找出真正优化点。

A METHOD OF CONSTRUCTING A SYSTEM'S MATHEMATICAL MODEL AND TRAILING ITS TRUE OPTIMUM POINT |
| |
| Abstract: | Author of this paper made both theoretical and practical investigation for searching a correct mathematical model to derive optimal solution in five aspects. The results showed: (1) by only t-checking, the degree of effects of all parameters on the objective could not be fully reflected. (2) effective range of regression equations are floated up and down around its theoretical value along with changes of the experimental conditions. (3) formal F-checking might not prove a good fitting model with reality. The author proposed a theoretical-experimental trailing method to acquire the optimum solution. |
