本文证明了Weyl定理在一定条件下对A类算子成立。我们还证明了Weyl谱等于一点集{0}的a类算子总是紧正规的。数学学科分类（2000）：47A53, 47B20。
In this paper, we show that Weyl’s theorem holds for class A operators under a certain condition. We also show that a class A operator whose Weyl spectrum equals to the one-point set {0} is always compact and normal. Mathematics subject classification (2000): 47A53, 47B20.
