摘要
本文阐述了特征有限元法的基本理论和实施过程,并给出了二个具体的计算实例。结果表明该法能消除大部分的数值弥散,而且又不增加解的振荡性。
The basic theory and enrorcement process of the characteristic finite element mentod are described and two calculation examples also given in this paper. It is showed that the method can dispel most numerical dispersion and the vibration of solution doesn't increase.
