| 1. | A pressure disturbance cannot drive the energy release profile uniformly to the anti-node region to result in a sustained longitudinal wave . 压力扰动不可能驱使能量释放分布图移至波腹区域以产生持续的纵向波。 |
| 2. | Unfortunately the shock conditions for accompanying longitudinal waves cannot be inferred at the outset without having detailed information about the shear wave . 很可惜,对伴随的纵波,冲击波条件却不能从一开始就在没有剪切波的详尽知识的情况下推测得出。 |
| 3. | A small angle incidence longitudinal wave for sensitive evaluation of fatigue cracks 超声小角度纵波灵敏检测疲劳小裂纹 |
| 4. | Node of longitudinal wave 纵波波节 |
| 5. | Recommended practice for immersed ultrasonic testing by the reflection method using pulsed longitudinal waves 液浸式超声纵波直射探伤方法 |
| 6. | Measurement of the longitudinal wave velocity and attenuation for underwater acoustical materials - pulse - tube method 水声材料纵波声速和衰减的测量脉冲管法 |
| 7. | Standard practice for immersed ultrasonic testing by the reflection method using pulsed longitudinal waves 用脉冲纵向波反射法进行浸入式超声探伤检验的标准实施规程 |
| 8. | The test results indicate that the above factors do not have much effect on ultrasonic longitudinal wave testing 试验结果表明,以上因素都不会对超声波纵波检测产生很大影响。 |
| 9. | Standard practice for detection and evaluation of discontinuities by the immersed pulse - echo ultrasonic method using longitudinal waves 利用纵波的浸入式脉冲回波超声法探测与评价不连续性的标准实施规范 |
| 10. | " sound : mechanical disturbance that propagates as a longitudinal wave through a solid , liquid , or gas . a sound wave is generated by a vibrating object . 声音:以纵波形式藉由固体、液体或气体传播的物理扰动。声波是由振动的物体产生。 |
