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。

The numerical results of the dispersion relation show some nonlinear effects: for a fixed geometry of a waveguid, beam parameters and plasma density, the increment of the modulation parameter may lead to a slight increment of the operating frequency, However, as the modulation parameter increases further, saturation may occur and the dispersion relations are hard to be separated, it is due to the overmodulation of the microwave power, this phenomenon itself belongs to the nonlinear effects.

五。用严格的场匹配方法分析了填充等离子体的耦合腔链，研究了等离子体一腔模的形成以及&冷&带宽和&热&带宽的展宽效应。等离子体填周期性耦合腔(来源：Aae53d3BC论文网www.abclunwen.com)链后，形成周期性的截止频率为0的等离子体TG模式。如果填充的等离子体密度较低时，腔模和槽模的工作频率均有小幅上升，而带宽改善不明显。

The linear dispersion relation of the enhanced equations is the Pad\'{e} [4,4] expansion of the linear Stokes dispersion relation, the accuracy of which is acceptable even when the relative water depth is as large as 1.0. Its nonlinear property and shoaling gradient are also improved.

改进后方程的线性色散关系达到了一阶Stokes波色散关系的Pad\'{e}[4，4]近似，在相对水深达1.0的强色散波浪时仍保持较高的准确性，并且方程的非线性和线性变浅率都得到了不同程度的改善。
