Based on this, a new WENO difference scheme which based on Dispersion-Relation-Preserving relation is developed, and representative test cases with this scheme for computational aeroacoustics problems has been implemented and compared in order to test capability of wave capturing; In addition, WENO schemes generally do not converge at high order in the presence of contact discontinuity of Euler equations, so a conservative front tracking technique coupling WENO schemes and Level Set method to simulate the translating density profile is presented here, and numerical simulation with this technique for representative test case has been implemented and results show the desired accuracy.

本文研究了高阶精度加权基本无振荡格式及其在双曲守恒律方程中的应用，在此基础上作了两个方面的工作：一是针对高频声波问题构造出一种基于保色散关系的WENO有限差分格式，并对计算气动声学问题的代表性算例进行了大量数值实验，比较了该格式捕捉波数的能力；另外，针对高阶WENO格式在处理Euler方程的接触间断时精度有所降低的问题，研究了利用界面追踪技术Level Set方法和高阶激波捕捉WENO格式相结合的一种守恒追踪方法，并且给出有代表性的密度滑移面问题的算例，得到一致高阶精度的数值模拟结果。

Not that we imagine any transubstantiation of bread into Christ's body, and of wine into his natural blood, as the Romanists have perniciously taught and wrongly believed; but this union and conjunction which we have with the body and blood of Christ Jesus in the right use of the sacraments is wrought by means of the Holy Ghost, who by true faith carries us above all things that are visible, carnal, and earthly, and makes us feed upon the body and blood of Christ Jesus, once broken and shed for us but now in heaven, and appearing for us in the presence of his Father.

不是我们想象任何陷于变体说的面包成为基督的身体，酒到他的血液中的自然，正如罗马法有恶性教人误认为，但这个联盟并结合我们已与身体与血的基督耶稣在正确使用的圣礼，是造成手段圣灵，那些由真正的信仰，我们进行上述所有的东西都是看得见，肉欲和尘世，使我们的饲料后，体内和血液基督耶稣的，一旦打破，大棚努力，但现在在天上，出庭为我们在场的他的父亲。
