偶极子声场 meaning in Chinese

dipole sound field

In chapter 2 , the fluctuate equation of monopoly sound field and dipole sound field is deduced detailedly , the root of this equation is given . analytical models is developed to investigate the noise of helicopter tail rotor , that is to say : the thickness noise and the loading noise is determined by a monopole source and a dipole source respectively
在第二章中对单极子声场和偶极子声场的波动方程及其求解做了详细的理论推导,建立了直升机尾桨的厚度噪声和载荷噪声计算模型,即可分别用单极子和偶极子声源描述厚度噪声和载荷噪声。
