| 摘 要： | 针对一维单个守恒律的初值问题研究了NND格式，在已有的数值方法的基础上，通过限制器函数的修正，提出了一类均匀二阶的高分辨率格式。数值实验结果显示，新格式具有较高的分辨率，且是无波动的。

| Abstract: | NND schemes were studied for initial value problem of a scalar conservation law. On the basis of study on numerical methods a new kind of uniform second order accurcy and high resolution scheme was designed by modifying the flux limiter. Several numerical experiment results show that the scheme has high resolution for shock waves, therefore they are non-oscillatory. |
