主　　题：Real-time holography distortion concrete 

摘      要：In order to find the relationships between the distortion rule ofthe concrete and its surrounding stress field, a real-time opticalholographic setup is used to record the distribution and thevariation of the samples, the waveforms of ultrasonic emissionstimulated by the micro-cracks are recorded by a transient automaticwaveform recorder to determine the time location and intensity of theactions of micro-cracks. The experiment results are worth *** method provides a useful experimental approach to study thebrittleness materials.
