摘要
本文从波的共性出发,以杆状介质中有耗能波过程这一物理现象为研究对象,应用波过程的贝杰龙(Bergeron)法的原理,首先导出介质中无损耗情形的力势波函数和速度函数的计算公式及对应的等值模拟线图。然后以其基本原理为依据,假设介质中有耗能时存在一个等值耗能参数元件,从而推导出介质中有耗能波动过程的计算公式。该公式可用于测量有耗能介质中的波过程的耗能值,为解决实际问题提供了一种近似计算的模型化方法。
Thc deduction has deen made of the calculation formrla of the wavc function of force potential the velocity function and the corrcsponding imitated isoplcth diagram in the in the case of no energy consumpion in the medium, by starting from the wave general character, studying on the wave proeess of energy consumption in the rod-like medium and using the bergeron principle in the wave process. Then the calcrlation formula has been made of the wave process of energy consumption in the medium according to the principlc, supposed that it exists a equal value parameter clcmcnt of cneryy consumption in the medium in the case of energy consumption. The formuld can be applied to mcasurc the value of energy consumption in the wavc proeess in the mcdium of cncrgy consumption and the modd method of approximate calculation has been given for the solution of the practical problcm.
