Our results reveal that with the same number of cobalt atoms and the same cobalt-substrate interation stength, the melting points and pre-melting intervals of the two kinds of supported Co clusters are all in reasonable agreement with each other. With increasing the depth of supported potential, the melting points increase for the supported cluster. Similar to the case of free clusters, the linear relation between the melting point and the inverse of cluster's size cube root is also found for the two kinds of supported clusters.

结果表明：对于给定原子数目的支撑Co团簇，在衬底势强度相同时，两种衬底势下对支撑团簇熔点及预熔化区间给出了一致的描述；随衬底势强度增加，支撑团簇熔点升高，且两种衬底势所描述的支撑Co团簇也类同于自由Co团簇都表现出较好的熔点与尺寸依赖的线性关系。

At and , we can get a univariate cubic equation in and its three roots . By the dependence of the roots and the coefficients of the equation, we can choose corresponding space points ( such that the distance is the shortest from to the point with parameters and . Thereby we can get all the data of discrete points on the cubic curve of blending surface at . Again we denote the maximum value and minimum value of planar parameter with which meets by and respectively.
