| 摘 要： | 对低温脉管机回热器的压力波的包络（调制）波波形进行了非线性回归拟合，得到了双曲正割孤立波波形，从实验上证实了该帽波是非等熵过程气动方程组导出的Ｋ－ｄＶ波动方程的孤波解，此结果为低温脉管的孤波制冷机理提供了支持。

| Abstract: | The nonlinear regression and fitting analysis for the modulated wareform of pressure wave on the reheater of pulse tube refrigerator is presented. The solitary wave in the form of hyperbolic secant was gotten, which affirms experimentally that the modulated wave is the solitary wave's solution of K-dV wave equation induced from gas dynamics equation set of non isoentrope process. It gives support to solitary wave refrigeration mechanism of pulse tube refrigerator. |
