在核物质的Ｈａｒｔｒｅｅ－Ｆｏｃｋ理论框架下，通过动量空间状态数的修正Ｈｉｌｌ－Ｗｈｅｅｌｅｒ公式来顾及核的有限尺度效应，应用Ｇｏｇｎｙ等效核力和唯象Ｃｏｕｌｏｍｂ能公式得到了合理的有限核零温饱和性质，得到有限核的液－气相变临界温度Ｔ＿ｃ约为１２ＭｅＶ，与由重离子碰撞实验提取到的一致。而且发现，目前广泛使用的有限核表面能唯象公式对于非正常核密度区是不适用的，本文给出了它的一个新的表达式。 Under the Hartree-Fock theory of nuclear matter, the finite-scale effect of the nucleus is taken into account by the modified Hill-Wheeler formula of momentum space state number. The reasonable limited nuclear zero-temperature fullness is obtained by using the Gogny equivalent kernel force and the phenomenological Coulomb energy formula And the nature of the finite core obtained liquid - gas phase transition critical temperature T_c is about 12MeV, and heavy ion collision experiments extracted. Moreover, it is found that the phenomenological finite element method of finite kernel surface energy which is widely used nowadays is not suitable for the non-normal nuclear density region. In this paper, a new expression is given.
