摘　　要：研究可加势和次可加势的水平集之间的联系与区别,发现并证明它们之间2个截然不同的性质,使人们对二者的关系有新的认识.The connection and difference between the level set of additive potentials and sub-additive potentials are discussed.We find and prove that there are two totally different properties between the two classes of level sets are found and proved.These results give a new understanding on this problem.

关 键 词：可加势 次可加势 水平集 JULIA集
