This paper simulated gas flow in vacuum high- pressure gasquenching furnace with finite volume method (FVM).
这里采用有限体积法对真空高压气淬炉中气体流动过程进行了数值模拟计算。

The service condition of aluminium alloy casting dies are analysed in this paper. The test of vacuum heat treatment process by high pressure gasquenching for the dies have been carried out.
We have studied and constructed a new detector by gas discharge and external quenching circuits to measure the low energy photoelectron emitted form the specimen surface.
