PVT仪中水银替代物的研制

THE DEVELOPMENT OF THE SUBSTITUTE FOR MERCURY WITH PVT EQUIPMENT

针对ＰＶＴ仪中水银传压介质的作用，研制成功了一种水银替代物。实践证明：这种替代物在用作传热、传压和计量介质时，不仅消除了水银的毒性，而且各项性能指标均能满足相态实验要求。

This paper presents a successful study of the substitute for mercury with PVT equip-ment.The use of the substitute can avoid the poisonusness of mercury. It is shown that thesubstitute performs as well as or better than mercury when used as heat-transferring andpressure-transferring medium.
