长信号

I have read complaints about other products taking a long time to get a signal..

我看过花费很长的时间去一个信号等产品的投诉。。。

Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair.

海底光缆有能力传送信号，超过更长的距离比同轴电缆和双绞线。

Since the detected signal isalways limited, according to the uncertainty principle, the frequency band is infinite.

由于观测的心率变异信号总是有限长的，根据不确定原理，所能得到的频带必然是无限的。

The model of fiber-optic Fabry-Perot interferometer was established when ideal or unideal optical source was applied. Through simulating interferometric signal by computer under the condition of nonmonochromatic light, the symmetry of fringes deteriorated, the fluctuating domain of fringes became small as the ratio of cavity length to coherence length increasing.

推导了光源在理想情况和非理想情况下的光纤Fabry-Perot干涉模型，通过计算机模拟了干涉信号，指出在非单色光源下，干涉条纹失去周期性，随着腔长相干长度比增加干涉条纹的变化幅度减小，最后演化成一条直线，条纹的可见度也慢慢趋近于零。

However, for long signal sequences, this algorithm will cost much time and space, so it becomes unpractical.

但是，在信号序列较长的情况下，该算法将占用大量的空间和时间，在实际中无法实现。

Can be a long time in the vicinity of the enemy's territorial waters or on the high seas cruising and roaming, and the enemy coast, combat ships and other targets in the sea and electronic surveillance: Receive and record enemy radio communications, radar and weapons control systems, electromagnetic waves emitted signal, these electronic devices to identify the tactical and technical performance; the identification of radio, radar and sonar station location and distribution system, identify the relationship between its command ; listening phones, intercepted and deciphered wireless telegraphy; tracking and monitoring ships and other marine activities.

能够长时间地在敌方领海附近或公海上游弋和漂泊，对敌沿海地区、作战海域和舰船等目标实施电子侦察：接收并记录敌方无线电通信、雷达和武器控制系统等发出的电磁波信号，查明这些电子设备的战术技术性能；查明无线电台、雷达站和声纳站的位置和配系，判明其指挥关系；侦听无线电话，截获并破译无线电报；跟踪监视海上活动的舰船等。

Bee said: Well, I said it, your head wore a long two antennas, the signal is so good, Zebu I send text messages

蜜蜂说：哼，还说我呢，你头上顶着那么长两根天线，信号那么好，咋不给我发短信呀！

In high precision conventional GPS kinematic positioning, the essential precision ambiguity resolution is obtained by GPS static measure for a long time before the airplane takes off or after it landed. And the cycle slip is disallowable.

利用动态GPS定位技术获取航摄仪摄站坐标的一贯做法是要求飞机起飞前和着陆后进行一段相当长时间的初始化并保持一个架次内GPS信号连续。

The research of signal processing methods for epicardial potential mapping system and the development of special cardioverterdefibrillator for surgery.

结果 本文一共采用了1 000多个心外膜信号样本(每个样本是单道10～20 s长的数据)对算法的检测效果进行测试。

Inaddition to that,LFY has a second role in the activation of the floral homeotic genes that specify the identity of organs in the flower and is a key intergrator of the outputs of floral inductive pathways.DFL, a FLORICAULA/LEAFY homologous gene,which cloned from C.lavandulifolium,was a key gene of florescence for C.lavandulifolium.

LEAFY基因在植物成花过程中意义重大，它不仅决定着花由营养生长向生殖生长的转变，它还接连GA成花途径和长日途径的信号继而诱导花分生组织的转变，同时还是活化花器官基因的关键基因。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
