| 摘 要： | 分析了发泡塑料气泡膨胀的热动力问题，从热动力学的角度阐明了气泡膨胀的条件、气泡膨胀的方向，分析得出气泡膨胀的动力是气液两相间的压强差，说明了气液两相间的质量传递和热量传递的根本原因，为进一步研究气泡膨胀的热动力学问题提供了理论基础。

| Abstract: | Thermal dynamics of bubble expansion during plastics foam process is analyzed.Conditions and orientation of bubble expansion are described.It is found that drive of bubble expansion comes from the pressure difference between phases of gas and liquid.The essential reason of the thermal and mass transfer between phases of gas and liquid is described. |
