We have first developed a new kind of particle detector using petrolic gas, which is based on the SQS (Self-Quenching Streamer) discharge mode.
我们首次用液化石油气制成粒子探测器。它工作在SQS方式。

When high temperature quenching, some of the vanadium carbide particles dissolved and the particle size of vanadium carbide decreased. But the distribution of VC particles hasn't been effected.
高温淬火时，部分碳化钒颗粒溶解，粒度减小，但对碳化钒颗粒的分布状态影响不大。
