traveling wave tube的用法和樣例：
例句
- The sound absorption coefficient of the material was tested by standing wave tube method.
採用駐波管法測試材料的吸聲係數。 - The effect of contact interaction between particles is decreased by the Riemann solver.Efficiency of the method is demonstrated by numerical tests of a 1D shock tube.
通過黎曼解近似粒子間的相互作用，減小接觸間斷附近的震蕩，並給出多介質一維激波管問題的算例，驗證此方法的有效性。
