本文引进内燃机活塞温度场热电比拟试验的结果。活塞系内燃机的主要零件之一,由于它经常地处于受热状态,可能引起过热或甚至损坏。在新设计内燃机活塞时,如果能得到活塞温度场的资料,那末可以改进活塞的结构,或者采取适当的冷却方法。因此内燃机活塞温度场的研究具有很大的实际意义。本文除简单地介绍电解池武热电比拟的基本原理外,并对试验的经过及结果作较详细的叙述。 In this paper, the results of thermoelectric comparison test of internal combustion engine piston temperature field are introduced. One of the main components of a piston-type internal combustion engine may be overheating or even damage due to its frequent heating. In the new design of internal combustion engine piston, if you can get the piston temperature field of information, then you can improve the structure of the piston, or take appropriate cooling method. Therefore, the study of piston engine temperature field has great practical significance. In addition to a brief introduction to the basic principle of EWC thermoelectricity, this article also describes the process and results of the experiment in more detail.
