摘　　要：给出Banach空间上斜演化半流的弱多项式膨胀的概念,并借助指数膨胀性的研究方法,讨论了满足弱多项式膨胀性的一些充分必要条件.The concepts of weak polynomial expensiveness for skew-evolution semiflows in Banach spaces are given and based on the extension of techniques for exponential expensiveness to the case of polynomial expensiveness,some necessary and sufficient conditions for the weak polynomial expensiveness are discussed.
