冲击波后温度测量的理论问题

THEORETICAL PROBLEMS OF TEMPERATURE MEASUREMENT IN SAMPLE UNDER SHOCK WAVE

本文讨论了冲击波后温度驰豫的理论方法。和R.Grovef及P.A.Urtiew不同,采用了非富利叶热传导理论,结果和实验十分符合,而实验结果用富利叶热传导理论是无法解释的。当时间趋于无穷时,这两种方法的结果又趋于一致,文章中作了物理原因的解释。

In this paper, the theoretical methods of thermal relaxation at interface following shock compression are reviewed. In contrast to the method adopted by R. Grover and P. A. Urtiew, the author solved the problem by the method of non-Fourier heat conduction. The result is in good accord with the experimental result which is difficult to interpret by the method of Fourier heat conduction theory, and when the time approaches infinite, both methods are coincident with each other. The interpretation of the physical reasons are discussed as well.
