引言 在便用热力蓄冷器的往复式低温制冷机中,如斯特琳(Stirling)循环,威留麦(Vuilleumier)循环,苏尔威(Solvay)循环和吉福特—麦克马洪(Gifford—Mcmahon)循环装置中,其性能是许多变量的复杂函数。即使对于最简单的单级系统,变量的数目也大约有25个。而且,在进行任何性能计算时,人们不得不做了大量假定或近似。 Introduction In reciprocating cryogenic chillers, which use a thermal regenerator, such as the Stirling cycle, the Vuilleumier cycle, the Solvay cycle, and the Gifford-McMahon ) Circulation devices whose performance is a complex function of many variables. Even for the simplest single-stage system, the number of variables is about 25. And, in making any performance calculations, people have to make a large number of assumptions or approximations.
