简易斯特林热机的制作与能量转化效率探究

摘要

A miniature Stirling engine has been designed and made.And the process of energy conversion has been studied.In this paper,we promote a new way to calculate the efficiency of energy conversion.This engine has some advantages of simple structure,whose materials are cheap and easy to obtain,and all the mechanical structure movements are clear for observation.It does wonderfully when it is used for the demonstration in physics experiment teaching.%文章设计和制作了一台小型斯特林热机,并探究了其能量转化过程,提出了一种新的效率计算方法.该热机的机械结构简单、运动过程清晰,材料便宜易得,用于演示物理实验教学效果良好.
