摘要
在重力场密闭于刚性容器中的气体密度随高度而减小,且气体的位能随温度而变化.利用密闭容器中的气体位能热循环可实现"热—功"转化过程,该循环有别于传统的卡诺循环(本文称其为"位能循环").进一步分析及总结出重力场中理想气体的位能热循环的熵变化计算方法.
In gravitational field , the density of the gas contained in a rigidity recipient decreases with height and varies with the changes of temperature. Accordingly,the gravitational potential energy of the gas will alternate when the temperature fluctuates. Such thermodynamic procedure of gravitational potential energy of gas can be employed to produce mechanical energy in a cycle way. In this thesis the author proposed a thermo--cycle,different from the traditional Camot cycle and named "Guorong cycle" , employing the gravitational potential energy of ideal gas to convert heat energy into mechanical energy. Additionally the entropy of the so called Guorong cycle is studied.
