摘要
给出了ATC-40迭代求解方法A收敛性的一个数学解释,分析了ATC-40迭代求解方法A和改进的能力谱方法在迭代上的差异,并从数学上证明了改进的能力谱方法有收敛的结果。
A mathematical explanation for the convergence of the ATC-40 procedure A is presented. The iterative difference between the ATC-40 capacity spectrum method and the improved capacity spectrum method is analyzed. And it is proved mathematically that the convergent result can be obtained using the improved method.
