| 摘 要： | In this paper a characterization theorem of the normality of products witha Lindel(?)f factor will be proved.The theorem as well as the well known Przym-usinski′s and Rudin′s characterization theorems of the normality of products wi-th a compact factor is a corollary of Theorem 1 below.Throughout this paper we assume that all spaces are T_1.The letterωdenotesthe first infinite cardinal;κ,λdenote the cardinal numbers and other Greek le-
