But this kind of open emission and reception system in High frequency communication has to face two challenges: firstly, natural interference from atmospherics and industry; secondly, tracing, blocking and multipath interference from enemy.

但这种开放式的发射和接收电磁波的通信，特别是在短波通信领域，不仅易遭到天电、工业等自然干扰，而且还要遇到敌方人为的跟踪、阻塞干扰以及多径等各种干扰。

The beat frequency can be thought of as an interference pattern in time, as opposed to the spatial interference pattern that is obtained with a passive Sagnac interferometer.

节拍频率可以被认为是干涉模式的时间，而不是干涉的空间格局是获得了一个被动Sagnac干涉仪。

The adaptive time-varying interference canceler is designed according to the estimated interference instantaneous phase.

5分析了压制式伪码调相干扰的形式及特点，定量研究了伪码调相干扰对伪码调相引信的影响。

The characteristic parameters of interferences are obtained by FRFT. Then the adaptive interference canceler is designed according to the estimated interference parameters.

该方法首先对观察信号进行FRFT，估计干扰的特征参数，利用估计出的干扰参数构造自适应干扰对消器，将干扰去除。

It's what we call constructive interference, or destructive interference...

也形成了我们所谓的结构干涉或解构干涉

Destructive interference hasbeen extensively studied both theoretically and experimentally,whereas only a fewstudies have been carried out for constructive interference.

目前，人们已从理论和实验上对相干相消进行了大量的研究，而相干相长的研究却很少。

This article intends to explore the hot issues in national and international emotional theories and national suicide crisis interference so as to produce some constructive advice on suicide interference in colleges and universities.

本文通过对国内外情绪理论、国内外危机干预现状等热点问题的探讨，为高校自杀危机干预提供一点有益的建议。

The phase-shifts caused by reflection and transmission of the beam splitter were investigated by its eigen-martix.The general relationship between these phase-shifts of two splitted beams used for coherent combining was obtained,then the fact that when constructive interference occurs in one side of the beam splitter and the destructive interference has to occur in the other side was explained in the point of phase-shift.

利用分束器的特征矩阵研究了分束时产生的反射与透射相移，得到了两束相干光经过分束器分束后进行相干叠加时相移满足的普适关系，从相移的角度解释了分束器一侧发生相长干涉时另一侧必然发生相消干涉这一现象。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
