方程激波计算的摄动有限差分方法 - The calculation of the position of the shocks for the domain decomposition of the hyperbolic approximation is discussed . it is the matching stable problem for the different schemes in the different domains with different mesh size . after tracing the position of the shocks , the artificial compression method are applied to eliminate the smearing effect and to raise the resolution of the schemes . in the boundaries of each regions , the universal connected matching stable schemes are inserted in so as to make the schemes between different regions matching stable each other . at last , some numerical examples are presented
讨论在激波计算中的区域分解法，即在不同区域中应用不同网格及格式的耦合稳定性问题.先定出激波位置，再在激波附近小范围内，用低阶格式及人工压缩方法以消除弥散效应.在激波区域外，应用高精度格式，减少了过超振荡现象，提高了分辨率.在各区域交界应用全能稳定联接格式，解决了格式的耦合稳定问题.最后举出数值计算实例，计算结果与理论分析符合
