以东京大学工业科学研究所ＫｅｎｓｈｉｒｏＴａｋａｇｉ教授为首的研究组，采用压电元件成功地产生出共相超声波。研究组以选通脉冲条纹摄影法采用超慢移动视频，还记录下水中倒向的共相波，目视即可证实这一情况。共相波的应用包括非损伤性地检验、诊断和治疗不透光的物...
A research group headed by Prof. Kenshiro Takagi of the Institute of Industrial Science at the University of Tokyo used piezoelectric elements to successfully generate a common phase ultrasonic wave. The study group used ultra-slow motion video with gated pulse streak imaging and also recorded the common-phase wave in the water. This was confirmed visually. Applications of common phase waves include non-invasive testing, diagnosis, and treatment of opaque materials...
