摘要：
A method of quick detection and identification on the early crack using AE (Acoustic Emission) technique is proposed which is based on the analysis of the early crack mechanism and characteristic. At the same time, the acquirement and identification of the early crack information are analyzed and investigated. It has guiding meaning on the early crack detection and identification of rotor to use AE.
