摘要：

Let p >= 5 be a prime number such that p equivalent to 3 (mod 8) and d an odd positive squarefree integer. Put K = Q(root 2, root-p, root d). In this paper, we compute the 2-rank of the class group of the fields K = Q(root 2, root-p, root d). Furthermore, we give the list of these fields whose 2-class groups are trivial, cyclic and of type (2, 2) or (2, 4).
