摘　　要：按照横波晶泛极化特性研制的新型双分量横波换能器用于声发射定位时,不但大大简化操作,减少换能器用量,而且显著提高信噪比.有效地提高声发射监测的定位精度.A two-dimensional shear wave transducer is developed according to the characteristics of polarization of shear wave plates. Using this transducer in acoustic emission (AE) , information about the direction of AE sources can be obtained. A new method to locate the AE source and to raise the Signals/Noise ratio is put forward.
