The transient natural convection and natural convective heat and mass transfer under constant-flux condition were also studied respectively. In experimental research, the electrochemical method was used to analogize natural convection in a porous enclosure.

在实验研究中，采用电化学方法，在多孔介质封闭腔体的两竖壁间建立浓度梯度和温度梯度，实验测量了腔体内的温度分布和电极间的极限电流，以此确定了总体的传热系数和传质系数。

The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.

介绍了该膨胀机的设计方法，给出了标准空调工况下的计算结果，详细讨论了两级旋叶式膨胀机的工作过程，并对两级膨胀机与传统旋叶式膨胀机的区别进行了论述，最后分析了滑片倾角对工作腔基元容积的影响，结果显示，滑片倾角对工作腔基元容积的影响很小，在膨胀机的设计过程中忽略滑片倾角的影响是合理可行的。
