These ferroelectric materials could be used as a cryogen.

具有电热效应的铁电材料就可以作为新型致冷材料。

Basic physics questions of operating in this cryogen need to be answered.

在这种制冷剂(液态烃)中操作的基本物理问题需要回答。

The liquid cryogen contacts the metal surface, generating a volume of expanding gas over the metal surface.

液体制冷剂接触金属表面，从而在金属表面上产生一定体积的膨胀气体。

The lance has a hood that directs both a flow of liquid cryogen and a flow of vaporous gas toward the metal surface.

所述喷管具有朝金属表面引导液体制冷剂流和蒸气流的罩盖。

The system includes a container of metal and a system configured to delivery biphasic inert cryogen toward the metal.

所述系统包括金属的容器和配置成朝所述金属输送双相惰性制冷剂的系统。
