查询词典 isochoric

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。

Synthesis of biodiesel by transesterification of rapeseed oil and methanol catalyzed by KOH/Al2O3 solid base was studied. The catalyst was prepared by isochoric impregnation. Effects of some factors on the transesterification were investigated systematically and reaction conditions were optimized. The optimum reaction conditions on KOH/Al2O3 catalyst were: mass ratio of KOH to Al2O3 20%; calcination temperature 400℃ for 5h; molar ratio of methanol to oil 12:1, the amount of catalyst 5wt%; reaction temperature 60℃ and reaction time 2h.
