引入了一类新的复合算子P: H2(T) H2(T)，具有：T/。得到了P有界和Hilbert-Schmidt的充分条件。研究了参数a和b的不同取值下，P与(eit) + be -it的性质。最后讨论了P的紧性
A new class of composition operators P: H2(T) H2(T), with : T/ is introduced. Sufficient conditions on for P to be bounded and Hilbert-Schmidt are obtained. Properties of P with (eit) ae it + be -it for different values of the parameters a and b have been investigated. This paper concludes with a discussion on the compactness of P
