中文摘要：

对三垂面基体上非自发形核进行了研究.根据非自发形核的条件,对临界形核半径和临界形核功进行了推导,得到了临界形核功与润湿角的数学表达式.结果表明,临界形核功仅与润湿角有关,说明润湿角在非自发形核中起非常重要的作用.对形核润湿角进行的讨论表明了,与自发形核相比,非自发形核具有更小的临界形核功.

英文摘要：

This paper focuses on the discussion of the heterogeneous nucleation on the substrate of three mutually perpendicular planes.According to the condition of heterogeneous nucleation,we study the critical radius of nucleation and the critical nucleation energy to form a critical nucleus,and obtain a mathematical expression of critical nucleation energy and contact angle.The result shows that the critical nucleation energy is only relevant to the contact angle and that the contact angle plays an important role in heterogeneous nucleation.The discussion on contact angles of nucleation indicates that the critical nucleation energy of heterogeneous nucleation is smaller than that of spontaneous nucleation.
