英文摘要：

In this paper, the property of two kinds of Roper-Suffridge extension operators in complex Banach space is discussed, and the fact is proved that the operators keep the properties of strongly spiral-like mappings of type β , strong and almost star-like map- pings of order α , strongly spiral-like mappings of type β and order α and almost spiral-like mappings of type β and order α , and as the special case, the results extend the known results.
