临界折射 meaning in Chinese

critical refraction

Based on the stress measurement model using the critically refracted longitudinal ( lcr ) wave , this paper discussed the key techniques of measuring the stress in accessories , which includes the generation , receiving and afterwards management of lcr wave . an experimental stress measurement system based on time was also designed and constructed in this project , by measuring the travel time of lcr wave in the medium , the stress state of testing object can be well evaluated
本文基于临界折射纵波( criticallyrefractedlongitudinal , lcr )应力测量模型,研究采用lcr波测量零件中切向应力的关键技术,包括lcr波的产生、接收和后续处理,设计并制作了基于传播声时的应力检测实验系统,通过测量lcr波在材料内部传播声时的改变,评估被测物体中的应力情况。
