摘　　要：本文引入了一个涉及Ruscheweyh导数的解析函数子类,应用微分从属方法和Carlson-Shaffer算子讨论了它的从属关系和偏差定理;其次,应用单叶函数的性质和一个微分不等式研究了它的星象性条件和覆盖定理.最后,部分地解决了Ruscheweyh的一个问题.In this paper, a subclass of analytic functions involving Ruscheweyh derivatives is introduced. We discusse its subordinate relations and distortion theorems by using differential subordinate method and Carlson-Shaffer operator. Next, we study its condition of starlikeness and covering theorems by using the properties of univalent functions and a differential inequality. Finally, we give a part of answer to a problem of Ruscheweyh.
