| 摘 要： | 对文1]中的时-空守恒元和解元方法(CE/SE)进行了改进和发展。改变了原格式的构造方法,由此得到的新格式不仅保留了原方法的优点,而且格式更为简单,通用性更强,也更容易推广到高阶和多维情形。

| Abstract: | The nontraditional method of space time conservation element and solution element (CE/SE), developed by chang S C in 1995, is modified. A new constructing method is used to obtain the calculating schemes. These new schemes not only have all the features which the CE/SE method has, but also are simpler, more accurate and have very high resolution of discontinuities. |
