The method is(1) fully explicit (2) fourth order of accuracy in time (3) high orderof accuracy in space by changing only one parameter (4) easy to operate on massively parallelcomputers efficiently, and it is robust in proceeding numerical problem.

• ( )通过对测试方案的求解和分析,可以看出该方法有如下的优点:(1)完全显式格式(2)时间上的四阶精度(3)仅仅通过改变一个参数就可以获得空间上的高阶精度(4)易于在并行的计算机上有效的执行,而且该数值方案有较强的健壮性。
