The technique requires considerable financial investment as the pressure vessel has to withstand the internal gas pressure and allow the powder to be heated to high temperatures.

因为压力容器必须经受住内气压并允许粉末加热到较高温度，所以这种技术需要相当可观的资金投入。

The flame velocity of flammable gas deflagration in a large closed vessel has an accelerating process, and the pressure distribution is not homogeneous.

大型密闭容器内可燃气体爆燃的火焰速度存在着一个加速过程，压力也不是均匀分布的。

Discharge tube: a closed insulating vessel containing a gas at low pressure through which an electric current flows when sufficient voltage is applied to its electrodes.

放电管：装有低压气体的封闭绝缘容器，当电极有足够的电压时，通过它电流就开始流动。
