L^p-L^q decay estimates of solutions to Cauchy problems of thermoviscoelastic systems

L^p- L^q decay estimate of solution to Cauchy problem of a linear thermoviscoelastic system is studied. By using a diagonalization argument of frequency analysis, the coupled system will be decoupled micrologically. Then with the help of the information of characteristic roots for the coefficient matrix of the system, L^p- L^q decay estimate of parabolic type of solution to the Cauchy problem is obtained.

试析《老人与海》的三重悲剧意蕴

《老人与海》是海明威代表性的作品,作品在健壮的老人奋力捕鱼而无所收获事实中展示了深层次的主题思想,在表现硬汉子精神的同时又彰显着明显的悲剧意蕴;通过对老人捕鱼的结果可以说明桑提亚哥的拼搏彰显着俄狄浦斯式的虚无悲剧,但在其捕鱼的过程中又表现着强者不败的硬汉子精神;最后从老人与鲨鱼搏斗的形而上学的意义上来理解又会发现作品中还流露着耶稣赎罪式的救赎意蕴。
