中文摘要:
      为了对气体多方指数进行定量的描述, 提出了一个随速度变化的气体多方指数的表达式;并以此表达式修正了Q-X方程, 而后, 以此方程对声空化进行了数值计算并与实验结果进行了比较。通过计算与比较, 发现:不同的多方指数, 对计算结果有较大影响;对不同实验条件, 都有一个最优的多方指数;修正了多方指数的Q-X方程与不同实验条件下的数据都拟合得比较好。表明所提出的随速度变化的气体多方指数的表达式是合理的。
英文摘要:
      In order to quantitatively analyze the gaseous polytropic index, an expression of the gaseous polytropic index changing with the velocity of bubble wall is put forward; and the Q-X equation is modified by this expression; then the numerical calculation of acoustic cavitation by this equation is done, and compared with the experimental date. As a conclusion, it is found that different polytropic indices give greatly difference results, there is a best polytropic index for a certain experimental condition, and the Q-X equation modified by the expression of the variable gaseous polytropic index can be coincident with the date in different experimental conditions. These indicated that the expression of the gaseous polytropic index changing with the velocity of bubble wall is appropriate.
