中文摘要：

尺寸依赖者团结 undercooling 为采用微分扫描热量计(DSC ) 的纯 Sn 的单个微尺寸的粒子被调查。粒子从溶剂封装 remelting 被获得并且熄灭(SERQ ) 过程。因为测量单个粒子的基本上未改变的球形的形状，在一系列连续加热并且冷却期间处理，它允许在 undercooling 上学习粒子尺寸的独立效果。与可得到的热力学的数据一起的适用的古典成核理论与减少的粒子尺寸产出增加的 undercooling。理论描述在对试验性的数据的好同意。

英文摘要：

The size-dependent solidification undercooling was investigated for single micro-sized particles of pure Sn employing differential scanning calorimeter （DSC）. The particles were obtained from a solvent-encapsulation remelting and quenching （SERQ） process. Because of the basically unchanged spherical shape of the measured single particles during a series of continuous heating and cooling processes, it allows studying the independent effect of particle size on undercooling. Applying classical nucleation theory in conjunction with available thermodynamic data yields an increasing undercooling with decreasing particle size. The theoretical description is in good agreement with the experimental data.
