通过深入分析和比较各种单级压缩混合工质节流制冷循环在低温热源为有限大热源时的热力学性能，揭示了不同循环型式之间的内在热力学关系，阐明了该类节流制冷机能够实现深度制冷的内在原因是利用了制冷机的内部热交换来减少节流制冷机所固有的节流过程的不可逆损失，并用实验进行了验证。

To analyze the landslide disaster from the angle of geology-meteorology coupling,the authors pointed out that the mechanism of meteorological landslide is an inconvertible self-organization-forming landsilde disaster system that primarily caused by precipitation,temperature and strong wind.

中文摘要：从地质-气象耦合的角度进行分析，指出气象类滑坡灾害的产生机制主要是降水、温度以及大风等气象因素引起潜在滑坡灾害系统产生不可逆的自组织过程———形成"滑坡灾害系统"。

The results show that the experimental results are in good agreement with the values of viscosity in a part of temperature range that has been reported, with the relative error of less than 2.5%; In the process of ascent and descent temperature, the irreversible phenomenon of the curve of viscosity versus temperature V presents interzone characteristic, and the break of viscosity at critical temperature reflects jump change of melt structural information; It is one to one correspondence between viscosity and atomic size, and this relation is consistent with the Hall-Petch formula in expression way.

结果表明：实验结果与已报道的部分温度区间内的黏度值基本一致，相对误差低于2.5％；升温和降温过程中，黏度－温度关系曲线V的不可逆现象具有区间特征，临界温度时黏度的突变反映出熔体结构信息的跳跃变化；黏度与原子集团尺寸之间存在一一对应关系，该关系在表达上符合Hall-Petch公式。
