    The mixture refrigerant with HFC-32+HFC-125 has friendly environment, and thermodynamic performances and safety performances, and can be considered as an alternative refrigerant of HCFC-22.But it is very limited for vapor-liquid equilibrium data of HFC-32+HFC-125. Therefore, vapor-liquid equilibrium data are studied based on the theory and accurate experiment.
    HFC-32+HFC-125由于具有良好的物性而被作为HCFC-22的替代物。 但是关于混合工质HFC-32+HFC-125的汽液相平衡数据很有限,这阻碍了混合工质在实际应用中的需要。

Hydrogen energy is an ideal alternative fuel when petroleum of the earth will be used up in the next century. This cycle scheme utilizes the hydrogenate of metal for solving the problems of reserving and carrying of hydrogen. The exhaust energy of the turbine is used to generate steam in the waste heat boiler. The gas-steam mixture enters into turbine and delivers mechanical work. The injecting steam has a lot of advantages. This paper makes the cycle's thermodynamic analysis and derives its thermodynamic...
