摘要
本文利用外界对系统的热功约束比（）概念，与热力学第一定律和理想气体基本性质相结合，推导出方程，揭示“理想气体准静态过程方程Ｐ＝Ｐ（Ｖ）的具体形式是由热功约束比决定的”客观规律．采用理论来论述，扩展加深了对理想气体准静态过程的认识．
By using the concept of heat power constrain ratio of systen fromoutside, conbining with the first law of thermodymamic and the bisic characters of idealgas, this paper deduced the equation.It revealed the objective law that spe-cific form of the quasistatic process equation P=P(V) was determined by heat powerconstrains ratio. Adopting theory, the knowledge to ideal gas quasistaticprocess was expanded.
