半经验的修正嵌入原子方法用于Ｎｉ，Ｐｄ和Ｐｔ的低指数面的表面应力计算，得到了与第一原理计算相符合的结果．给出了（１１０）表面［１１０］方向的应力是［００１］方向应力的两倍左右；阐明了应力各向异性是所有ｆｃ金属（１１０）面的一般特性．预言了Ｐｄ和Ｐｔ（１００）的表面应力的大小．
The semi-empirical modified embedded-atom method was used to calculate the surface stress of the low-index planes of Ni, Pd and Pt, and the results that were consistent with the first-principle calculations were obtained. It is shown that the stress in the [110] direction of the (110) plane is about twice as that in the [001] direction; and the stress anisotropy is the general characteristic of all the (110) fc metal surfaces. Predict the Pd and Pt (100) the size of the surface stress.
