摘　　要：本文研究了特征零的代数闭域上秩为4的有限维特殊Cartan型李超代数S的结构.利用正则元的划分,确定出S关于典范环面的所有正根系,从而得到了S的所有Borel子代数;对于每一个正根系,通过给出其单根系,得到了任何两个Borel子代数的连接关系;最后确定了每一个Borel子代数的极大可解性.本文所得结果可用于进一步研究Cartan型单李超代数的结构与表示.This article studies the structure of a finite-dimensional bpemal t,m superalgeuraS of Cartan type of rank 4 over an algebraically closed field of characteristic zero. First, wecharacterize all the positive root systems with respect to the canonical torus by means of classifyingall the regular elements and in particular we obtain all the Borel subalgebras with respect to thecanonical torus. Second, we describe the connection relation between any two Borel subalgebrasby means of determining the simple root system for every positive root system. Finally, wedetermine all the Borel subalgebras which are maximal solvable subalgebras. The main results canbe used in the future for studying the structures and representations of the finite-dimensional Liesuperalgebras of Cartan type
