查询词典 signals

He suggested the following figures should be multiplied: how many stars are formed in the galaxy in a year; what fraction of these have planets and thus form solar systems; the average number of planets per solar system that have the potential to support life; on what percentage of those where it is possible do such biospheres actually form; what percentage of such biospheres give rise to intelligent species; what percentage of intelligent life is able to transmit signals into space; and for how long could such intelligence keeps sending signals.

他的方法包括一系列应该纳入考虑范围的数据：银河系每年新诞生的恒星数；拥有行星并组成了星系的恒星比率；有可能会出现生命迹象的行星平均数；以上行星能够真正孕育生命的比率；演化出了智能物种的比率；能使用无线电通讯与外太空联系的智能生物比率；智能生物使用无线电通讯方式的持续时间。更多信息请访问： http：//www.24en.com

We proposed that the non-adiabatic passage at zero-crossings of quadrupole splitting would not lead to the great loss of the spin locking signals, and the second-order quadrupolar interaction had significant effects on triple-quantum coherences, which was responsible for the fast decay of the signals; the both experiments and numerical simulations supported this point of view.

另外，在该谱仪上还进行了四极核钠-23的自旋锁定效率的研究；从含时Shr〓dinger方程出发，提出了一个更为确切的四极分裂过零处的绝热通过判据，并指出四极分裂过零处的非绝热通过不会导致锁定信号的快速消失，四极相互作用的二阶项对三量子相干的影响不能忽略，它是引起锁定信号快速消失的原因；实验和数字模拟的结果证实了这个理论。

Their downside is that they give premature sell signals in uptrends and buy signals in downtrends.

在上涨时提前给下跌的信号，在下跌时提前给上涨的信号。

The opposite occurs in downtrends, when trend-following indicators turn down, giving sell signals, while oscillators become oversold, flashing buy signals.

下跌时相反，当趋势跟踪指标下跌时，振荡指标认为超卖了，发出买入信号。

An effect associated with the reception of frequency-modulated signals in which, if two signals are received on or near the same frequency, only the stronger of the two will appear in the output.

与调频信号接收相关的效应，如果两个信号出现在相同频率上或者是频率接近的区域，只有信号功率较大的一个信号将进入设备输入端。

It was shown that for small input signals, operation is limit- ed in so small a portion of the characteristic that much smaller than usual grid bias may be used to obtain higher trangconductance, and consequently higher gain; whereas for large input signals,non-linearity of the characteristics limits the maximum output obtainable.

证明要得到没有畸变的调幅，必须使阳极电压、屏栅极电压、栅偏压和栅极激励用上压同时加以调制。所要求的调制方式都是很近于同比例的。

Besides, by the application of the two kinds of similar Haar wavelet transforms, typical fault signals in power systems are analyzed. It is proved that the two kinds of similar Haar wavelet transforms are very effective methods of the detection of fault signals in power systems.

此外，本文借助于这两种相似Haar小波变换，分析了电力系统几种典型的故障信号，证明了这两种相似小波变换方法对于检测电力系统故障信号是非常有效的。

TNT,Dynamite or Torpedoes, Distress signals, Fuse igniters, Ammunition for hand weapons, for signals, Safety Fuses, certain types of Fireworks, etc.

例如︰TNT 、炸药或鱼雷，遇险信号、保险丝发火器，信号弹、导火线、某些类型烟花等。

For narrow-band signals, three uniform linear arrays, whose grating lobes are not overlapped by setting the angles between the arrays and the same pointing of main-lobes, are used and then multiplication of three patterns is operated to reduce the grating lobes of large-spaced array, which makes the array operate in broad band. For wideband or ultra-wideband signals, array pattern in the whole frequecy band is identical by designing the frequency-dependent weighting coefficients based on the Bessel function, and therefore grating lobes in high frequency parts are suppressed.

对于窄带接收信号，利用三个相交的大间距均匀线阵，通过设置它们之间的角度和主瓣指向相同使各自的栅瓣位置错开，然后把三个方向图相乘从而抑制大间距阵列栅瓣，因而适用于宽频带工作；对于宽带接收信号，利用Bessel函数设计与频率有关的加权系数，产生整个信号带宽内恒定的方向图，从而抑制了高频部分的栅瓣。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
