摘要
针对一阶一维常系数双曲型方程,给出了关于乘积型差商空间中的组合差商法的概念,藉此分析了节点分布与差分格式类型和精度之间的关系,并给出了它的具体应用,同时用数值实例验证了理论分析的结果.
In this paper, one-order one-dimensional constant coefficient hyperbolic equation is refered. At first the authers give some basic definitions about combination difference algorithm in product difference space. On this foundation the authers analyze the relation of node distributing and type of difference schemes. Then in product difference space by applying combination difference algorithm, series of difference schemes are constructed.
