根据橡胶气球的热力学性能及门尼模型理论，推导出橡胶气球膜在充气与放气两个过程中受到的附加压强与气球半径的关系，并以此推导出不同半径气球内部的压强，以及两个相互连通的气球体积变化与内部压强的关系，理论结果与实验相吻合.将橡胶气球模型应用于简易气垫船研究，建立了气垫船运动模型，并利用实验结果对理论模型进行了修正.

According to the thermodynamic properties of rubber balloon and the theory of Mooney model，we derive the relationship between the additional pressure and the radius of rubber balloons' membrane during inflation and deflation when two balloons are connected，and the relationship between the two connected balloons' volume changes and internal pressure is also obtained. The theoretical results are in agreement with the experimental results. Applying the model into the research of the simple model of the hovercraft，we take use of the experimental results to modify the theoretical model.
