A particularly troublesome type of multiple produces the coherent noise known as singing . 一种特别伤脑筋的多次反射引起同相干扰,这种干扰称为鸣震。
We must seek two main approximation methods of solution, the variation method and perturbation theory . 我们必须寻求两个主要的近似解法、变分法和微扰法。
When measuring a shallow diffused layer at low concentrations, reliable measurement free of noise are difficult to make . 测量低浓度浅扩散层时,无干扰的可靠测量很难实行。
They achieve the desired result by reducing the lift and increasing the drag on the side where the spoiler is raised . 由于扰流器打开的一侧升力减小而阻力增加,从而达到所要求的效果。

The hardened professional smuggler is never troubled by such feelings , even if he has five hundred gold watches hidden in his suitcase . 而老练的职业走私犯,即使他的手提箱里藏了五百只金表,却从来没有被这种感觉所扰过。
The high clock frequency requirements will have to be weighed against the need for tighter design criteria that ensure high noise immunity . 高时钟频率的要求比高抗扰度的要求更为重要,因为高抗扰度可通过精心设计予以保证。
I could not find any sixpenny entrance and, fearing that the bazaar would be closed, i passed in quickly through a turnstile, handing a shilling to a weary-looking man . 我找不到只化六便士就可以进去的入口,心里担扰着集市就要打烊了,于是向一个面带倦意的守门人交了一先令,很快穿过一个旋转式的栅门。
