英文摘要：

The classical integral characterization of Holder continuous functions plays an important role in regularities of elliptic PDE＇s. In this paper, by taking use of Morrey and Companato space theory on metric measure spaces, we prove an integral characterization of Holder continuous functions on CC metric measure spaces.
