The kinetics of the first order liquid-liquid transition (LLT) in a single-component liquid D-mannitol have been examined in detail by the high rate of flash differential scanning calorimetry measurements. By controlling the annealing temperature, the phase X formation from the supercooled liquid is distinguished by either a nucleation-growth or a spinodal-decomposition type of LLT. In the measured time-temperature-transformation curve the portion covering the nucleation-growth type of LLT can be well fitted with a classical nucleation theory analysis.
利用高速差示扫描量热法详细研究了单组分液体 D-甘露醇中一级液-液相变（LLT）的动力学。通过控制退火温度，可以通过成核生长或旋节分解型 LLT 来区分过冷液体中相 X 的形成。在测量的时-温-转变曲线上，覆盖成核生长型 LLT 的部分可以很好地用经典成核理论分析来拟合。
