这个相变在热力学上为一级相变。
观察到一级相变点值变大，二级相变点值变小，反应窗口变宽。
It is observed that the width of the reactive window is broadened, the first critical point becomes larger and the second critical point becomes smaller.
在相变温度区域里，介电、热电和压电都有明显的热滞效应，具有一级相变特性。
Near the transition temperature, a thermal hysteresis was found in dielectric, pyroelectric and piezoelectric measurements. Thus the transition should be of the first order transition.
发现采用商业级钆配制合金时，由于杂质抑制了材料的一级相变，未发现巨磁热效应。
The first order phase transformation in the samples made of commercial Gd was destroyed by impurities, and no giant magnetocaloric effect was found.
当入射光仅包含位相涨落时，噪声相关时间对一级相变类比的参数区域也产生很大影响。
If only the phase fluctuation is included in the incident light, the correlation time can also affect the parameter plane of the FOLT.
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。
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.
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。
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.
