Bo - Tau Liu, etc. [6] through the study found, Molecules of hydrogen bonding material are not suitable for as working medium of organic Rankine cycle.
But many shortcomings are still exists.For example, when the heat source temperature at 150 ˚C, compared with other working medium, because of the HFC class material with high cycle efficiency ,it is widely used and researched because of its obvious advantages,but since it has higher GWP value, it must eventually be eliminated; To the heat source of 300 ˚C temperature, Alkanes and benzene class working medium has good comprehensive performance and is widely used, but due to its flammability, which threat to system security.

Stability analysis of main structure for an open-cut metro station Yanhui Guo , Kepeng Hou Faculty of land Resource Engineering, Kunming University of Science and Technology, Yunnan Kunming, China guoyanhui0818@163.com, 418483499@qq.com Keywords: stability; open-cut; main structure; metro station; numerical analysis Abstract: Based on a metro station background of the line 3 west extension engineering of Kunming metro line co.LTD.
Figure 5 shows the maximum principal stress of main structure after completion of the metro station, the maximum principal stress of main structure of the metro station is given priority to compressive stress, which is conductive to the performance of concrete material itself.
The maximum principal stress of main structure of the metro station is given priority to compressive stress, which is conductive to the performance of concrete material itself, the main structure of metro station tend to be stable

Theoretical Determination of the Working Environment Influence on the Deflection of Shaft in Console In dynamic conditions (during rotation of shaft) as shown in Fig 1, mass mt will produce a centrifugal force, determined by Eq. 1: (1) The elastic force of the shaft is: (2) where, - k is the elastic constant of the material shaft - fdin - elastic line deflection of shaft in dynamic conditions.
So, (18) From Eq. (18) it results: (19) It were noted with rot and rla densities of mixer material and of entrained fluid.

Introduction With the progress of the society, people's material life has been greatly improved, but at the same time people attention to the mental health but have not reached the level of material life, and a variety of psychological problems highlighted increasingly.
Psychological test evaluation can help student understand their identities, angry and qualitative points, ability to pour into, health status, etc., and provide them with developing their own potential forecast information and the goodness of science according to according to self, enabling them to clear the direction of the self-improvement, improve psychological quality, happy life and learning efficiently.
