unchangeableness

基本解釋

The bending of simple supported beam make the resonance peak wavelength of each mode of TFBG shift and resonance peak amplitude unchangeableness.
簡(jiǎn)支梁的彎曲只讓TFBG各模式的諧振峰波長(zhǎng)發(fā)生了漂移，而各模式的諧振峰的幅度沒(méi)有改變。
The test indicates that the method not only can reach to a satisfactory speeding effect, but also can keep very well the failure mechanism unchangeableness.
試驗(yàn)證明，該方法不僅可以達(dá)到令人滿意的加速效果，而且還極好地保持了失效機(jī)理的不變性。
This paper also discusses the principle of the electromagnetic power unchangeableness to some extent.
