非线性模型实用处理方法探讨

Discussions about practical data processing on non-linear models

本文结合非线性模型通常采用迭代计算方法处理的实际,指出在给定初值的情况下,直接依据迭代计算结果的收敛情况来判别非线性模型能否进行线性化,可以避免对非线性强度指标的复杂计算,从而简化判别过程中的数据处理方法;实例表明,相对已有非线性强度指标的计算,依据迭代计算结果判断非线性化模型的线性化度量,计算简洁,可靠性更高。

Considering the fact that processing the non-linear model with iteration method, this paper suggested that whether the model is linearized could be proved by the results of the iterations instead of the nonlinearized strength indexes which are difficult and complicated to be obtained. The experiment showed that the reliability could be improved simultaneously by real calculations of the method.
