The Standardization for Time of Flight Diffraction Technique

Time of flight diffraction is a new advanced technology of ultrasonic testing. It is accepted for the advantages of automatic and high speed scanning with intuitive display. Now due to the fact that there is a lack of strong support of the relative criterion and kernel technique of equipment, so technical barriers might appear with the deep influence to the schedule of research and industrialization of our country. But it is just the good opportunity to establish our independent technique and realize the strategy of industrialization.
