压缩的

In order to figure out the use of compression in the wood preservation aspect, the authors compared the compressed wood samples pretreated with hot water bath or water spraying and compressed preservative-treated wood, which was treated with ammine copper quat-type D preservative solution. The liquid absorption and recovery rate of compression deformation of the compressed wood were determined, as well as the surface hardness, distribution of density and CuO retention in the thickness direction of CPW.

It is shown that the generation of the PA effect results from two kinds of contribution only. One is the contribution of so called"thermal piston"--the gas boundary layer adjoining the heated sample which expands cyclically and pushes the rest gas just like piston. The compressing process of it is comfirmed to be isochoric. And the other is that of"mechanical piston"--the thermally expansive sample itself, the compressing process of which is found to be polytropic with a index of (2-〓).

一即是被称为&热活塞&的与材料受热表面相邻的边界层气体周期性热膨胀产生的压缩，其是定容过程；另一是被称为&机械活塞&的材料本身热膨胀产生的压缩，其是多变过程，多变指数为2-〓，γ为绝热压缩因子。
