Initial-boundary value problems for a class of nonlinear thermoelastic plate equations

This paper studies initial-boundary value problems for a class of nonlinear thermoelastic plate equations. Under some certain initial data and boundary conditions, it obtains an existence and uniqueness theorem of global weak solutions of the nonlinear thermoelstic plate equations, by means of the Galerkin method. Moreover, it also proves the existence of strong and classical solutions.

一种新型的壳管防冻控制技术的研究

针对于风冷冷热水机组,由于机组放置室外,在环境温度低于0度时,壳管的防冻问题是关键,通过分析壳管中水温的分布以及变化,得出如无额外热源提供给壳管,壳管将会产生冻裂的危险,通过分析壳管中的水温在不同环境温度下的变化,控制额外热源的供热,可保证壳管中的水不会结冰,避免壳管出现冻裂,本文提出了一种新型比较理想和节能的壳管防冻控制方案。
