介绍用自行研制的单片微处理机控制的振动波时差采集显示仪进行动态无损检测建筑构件质量的新技术，该检测仪结构简单、袖珍轻便、价格低廉并满足辅助工程测试要求精度。
This paper presents a new technology for the dynamic non-destructive testing of building components using a self-developed single-chip microprocessor-controlled vibration-wave time-difference acquisition display. The detector is simple in structure, lightweight and portable, and inexpensive to meet the requirements of auxiliary engineering test requirements.
