中文摘要：

分析了教材中关于液态金属凝固热力学条件和形核热力学中的公式推导过程,发现教材中存在参数的量纲前后不一致而得出错误结果的现象;通过统一量纲,获得了均质形核的正确临界晶核半径计算式,并通过实例对其正确性进行了检验.结果表明,所获得的临界晶核半径计算式正确.

英文摘要：

One of the important problems for materials science is the thermodynamics of solidification and nucleation. The derivation procedure of the formulae relating to consolidation and nucleation thermodynamics for liquid metals in some teaching materials was analyzed in this paper. It is found that there is dimensional heterogeneity of some parameters, resulting in the wrong results. By unifying the dimension of parameters, the corrective relationship of the critical diameter of crystal nucleus for homogeneous n...
