first order phase transition

基本解释

In chapter 2, a familiar system -gas-liquid coexistent system which is concomitant of first-order gas-liquid phase transition is discussed.
第二章中探讨了伴随一级相变的常见体系—气液共存体系。
They discovered a first order phase transition, a discontinuity, in liquid hydrogen between a molecular state with low conductivity and a highly conductive atomic state.
他们发现了一个不连续的一级相变，这个相变是在液态氢低电导率的分子态和高电导率的原子态之间。
For smaller clusters, there is no clear characteristic of first-order phase transition during the melting, implying a coexistence of solid and liquid phases due to finite-size effect.
对于较小的团簇，融化曲线没有出现清楚的一级相变特征，意味着由于尺寸效应导致的固态液态共存。
