一种富于启发性的热机实验演示与分析

An enlightened demonstration on an experiment of heat engine

利用试管、玻璃球、注射器、圆盘等易取材料研制了使玻璃球通过重力作用原理来转移工作物质的方法 ,并可用燃烧热、电阻热和光转化热作为高温热源的动力的热机实验演示 .同时我们给出了相应的理论分析 .

A demonstration of heat engine is constructed with some simple appliance such as test tube,glass ball,injector and disc,and theoretical analysis is given.
