摘 要: 常用的测量气体比热容比的方法有绝热膨胀法、声速法、小球振动法等,然而这些方法所用设备和测量原理都相对复杂。本文研究了测定气体比热容比的原理,探讨了测量理论,进行了推理演算,并设计了一种实验装置和测量步骤。实验数据和结果表明:该方法测量气体的比热容直观、精确且简单。 The measurement methods for the ratio of specific heat capacity of the gas are generally including adiabatic-expansion method, sound-velocity method and small-ball vibration method, etc.However, the equipment and the measuring principle of these methods are relatively complex. In this paper, the principle of measuring the ratio of specific heat capacity of gas is studied, and the calculation based on deduction is carried out. The experimental data and results show that this method can measure the ratio of specific heat capacity of the gas directly, simply and accurately.
