Under ultrasonic interval loading with air cooling, it all occurred at an internal inclusion in the whole stress amplitude level.

压缩空气冷却的间歇加载超声试样，在全应力幅范围均为夹杂物引起的内部破坏。

In some cases, the continuous distribution model of fatigue failure life and stress amplitude level is more valuable in analyzing the damage of ponogena under complicated stress.

在某些情况下，如进行复杂应力条件下的疲劳素损伤分布分析，疲劳失效寿命和应力幅水平的连续分布模型更有意义。

One is called the S-N curve of surface fracture mode. It is governed by a crystal slip on the specimen surface, which occurs in the region of short fatigue life and high stress amplitude level.

一组叫做表面破坏模式的S-N曲线，它发生在高应力幅短寿命区，是由试样表面晶体滑移引起的。

And when we're talking about the amplitude of the wave, we're talking about the deviation from that average level. So, if we define the average level as zero, you can have either a positive amplitude or a negative amplitude.

当我们讨论一个波的振幅时,我们说的是偏离平均位置的量,如果我们把平均位置,定义为零的话，那幅值不是,正的就是负的，有时候人们在。

Participants will assess the feasibility of exchanging sea-level data which can confirm the tsunami and provide information on its amplitude although, in the Mediterranean, due to short tsunami waves travel time, it is not always possible to wait for such confirmation before issuing the alert.
