摘要：
We establish a link between some heuristic asymptotic formulas (due to Cohen and Lenstra) concerning the moments of the P-part of the class groups of quadratic fields and formulas giving the frequency of the values of the p-rank of these class groups. Furthermore we report on new results for 4-ranks of class groups of quadratic number fields.
