A method for measuring the mono sound power in thermoacoustic resonator was developed by using the theory of plane wave decomposition.
提出了通过平面声波分解测量热声谐振管中单频压力波声功的方法。
In this paper, the interaction between a cw plane wave and a plane pulse travelling with sound speed is considered. Both of them satisfy the homogeneous wave equation.
本文讨论一列平面波与一列平面行波脉冲的声相互作用，显然这两个波不仅都满足波动方程，而且可以用来讨论公共区之外的声散射声问题。
The plane wave error is always negative windage, when the sound wave is the cycle function of space and time.
当声波是空间位置和时间的周期函数时，平面波误差项永远是一负偏差项。
The sound fields of the parametric line array can be analysed by it. Firstly, the point-source function is expanded into an operator on a plane wave function.
首先将点源函数展开为一个算符对平面波函数的运算，经过计算证明，如果将这个算符对参量阵远场解进行运算，得到的结果即为线源参量阵辐射场的解。
