中学物理“热机”一节课的原实验具有一定的危险性,且趣味性不强。为此,笔者在网上查找发现了一种热机——斯特林热机,可以作为实验教具。该发动机是伦敦的牧师罗伯特·斯特林(Robert Stirling)于1816年发明的,所以命名为“斯特林发动机”(Stirling engine)。斯特林发动机是独特的热机,理论上其效率几乎等于理论最大效率,称为卡诺循环效率。斯特林发动机是一种外燃发动机,将燃料连续地燃烧,以蒸发的膨胀氢气(或氦)作为动力气体使活塞运动,膨
High school physics “heat engine ” a class of the original experiment has a certain degree of risk, and the interest is not strong. To this end, the author found a hot machine online search - Stirling heat machine, can be used as experimental teaching aids. The engine was invented by a London pastor, Robert Stirling, in 1816 and was therefore named the Stirling engine. Stirling engine is a unique heat engine, in theory its efficiency is almost equal to the theoretical maximum efficiency, known as the Carnot cycle efficiency. The Stirling engine is an external combustion engine that continuously burns fuel and uses the vaporized expanded hydrogen (or helium) as a motive gas to move the piston
