| 摘 要： | 在Ｔａｒａｚｏｎａ的内禀自由能的权重密度近似的基础上，我们提出了一个新的权重函数和一新的内禀自由能密度泛函．应用这一泛函，我们计算了硬球—硬壁介面的密度分布。得到了与模拟结果更好的符合。

| Abstract: | On the basis of Tarazona's weighted density approximation to the intrinsic free energy functional,we propose a new weight function and an intrinsic free energy functional.With this functional,we calculate the density profile of hard sphere-hard wall interface. The results show that the new functional is better than those proposed originally by Tarazona. |
