In the feudal autocratic rule, any system implemented by the state will have an important influence on all aspects of the whole society~ especially it is related with the imperial examination system of education and talents. Once it becomes a "basic national policy" , the role in social development is incalculable. This paper takes the relationship between imperial examination system and Tang and Song prose development as the breakthrough point, analyzing the influence of thesis writing of imperial examination on the prose in Tang and Song Dynasty and "Eight great men in Tang and Song Dynasty" .展开更多

Analysis of the 1st law of thermodynamics for an ORC system is performed. This analysis contains two parts. The first part is an analysis with undefined heat exchangers to gain an understanding of the ORC and find out suitable organic fluid parameters for a better ORC efficiency. The second part of the analysis uses combined engine test results and two designs of heat exchangers. By comparing the two designs, an improved system of heat exchangers is described. This analysis also quantifies the effect of engine parameters on ORC system. The study concludes that the supercritical Rankine cycle is a better approach towards waste heat recovery. The ORC system is found to perform better under part-load conditions if the medium-high power condition rather than rated working point of the engine is used as the design parameter. The ORC system achieves the highest waste-heat recovery efficiency of up to 10-15% for the optimised heat ex-changer design.展开更多
