基本例句
纵波
Since sound waves are longitudinal, only one dimension need be considered to obtain the sound wave solution.由于声波是纵波，所以为了得到其解，只需考虑一维就行了。
This paper deduces the errors sources from the process of ultrasonic longitudinal wave testing and evaluates its uncertainty.本文分析了超声波探伤纵波检测的误差来源，评定了在探伤过程中的不确定度。 |
