| 摘 要： | 指出传统振动法测气体比热容比实验的不足之处。设计了一种新的实验方法,通过改变气流方式以降低振动小球与管壁的碰撞机率,控制振动小球的振幅使之更接近简谐振动.并利用原有的光电计数仪,调整计数次数.测量显示,实验值更接近双原子的比热容比值。

| Abstract: | The disadvantage of the traditional vibration method to measure gas specific heat ratio is discussed,and a new experimental method is proposed.By changing the gas flowing pattern,the probability of collision between the vibrated ball and the wall can be reduced.Through controlling the vibration amplitude of the ball,the vibration motion tends to be harmonic oscillation.Besides,the number of the count is adjusted by using the original photoelectric counter.The measurement shows that the experimental value is closer to the specific heat ratio of diatomic gas. |
