Dead zone, английский
- An area in an ocean or large lake where oxygen levels are extremely low, often due to eutrophication. dead zones have been increasing since the 1970s.
- Zone in the test part directly underneath the sound entry surface where discontinuities cannot be detected; caused by the finite length of the initial pulse, ringing time of the transducer element, and/or electronic characteristics of the instrument.
- Interval following the initial pulse at the surface of a test object to the nearest inspectable depth. any interval following a reflected signal where additional signals cannot be detected.
- Интервал после первоначального импульса на поверхности объекта контроля до ближайшей контролируемой глубины. любой интервал после отраженного сигнала, где дополнительные сигналы не могут быть обнаружены.
- In ultrasonic testing, interval following the initial pulse at the surface of a test object to the nearest inspectable depth.18 any interval following a reflected signal where additional signals cannot be detected.
- Interval following the initial pulse at the surface of a test object to the nearest inspectable depth.21 any interval following a reflected signal where additional signals cannot be detected.7 558 ultrasonic testing decibel (db): logarithmic unit for expressing relative signal power, such as the loudness of a sound, in proportion to the intensity of a reference signal. one tenth of a bel. decibel in signal amplitude is twice that in signal power.16 one decibel equals ten times the base ten logarithm of the ratio of two powers.
