本文证明了Yamazaki在文[23]中的结果对于文[13]中引入的算子类A（包括p -亚正规算子和对数-亚正规算子）仍然成立。此外，我们还将给出与[8][12][18]和[19]中关于超自然的性质相对应的关于类A的几个性质。数学学科分类（1991）：47 B20，47 A63。
In this paper, we shall show that Yamazaki’s result in [23] remains valid for class A introduced in [13] as a class of operators including p -hyponormal and log-hyponormal operators. Moreover we shall show several properties on class A which correspond to the properties on paranormal in [8][12][18] and [19]. Mathematics subject classification (1991): 47B20, 47A63.
