If lots of flexible antennas attached to small radios were placed inside a bridge, they would expand or contract along with the bridge and so would constantly retune themselves.

如果许多可伸缩天线附着在微型无线电收音机上面，并且放置于大桥内部，它们就会随着桥相应地伸展或收缩，这样就会经常性的自我调谐。

A single-longitudinal mode fiber laser with fiber saturable absorber is designed. Tunable fiber Bragg grating as the wavelength selector is in the ring cavity with a 2 m-long unpumped erbium-doped fiber.

设计了一种基于光纤饱和吸收效应的环形单纵模光纤激光器结构，以可调谐光纤布拉格光栅作为波长选择器件，与2 m未抽运掺铒光纤一起位于环形腔反射臂上。

To realize single longitudinal-mode of the fiber laser, a ring configuration is devised. The single longitudinal-mode operation is realized by using a fiber Bragg grating as wavelength-selective element and a unpumped 2m-loog erbium-doped fiber which can produce stading-wave saturation effects in the cavity, Its tunable wavelength range is 42 nm, the output power is more than 3.5 dBm and the stability is less than ±0.005 dB.

为了实现光纤激光的单纵模，提出了一种环形腔结构，采用可调谐光纤Bragg光栅作为波长选择器件，与2m未抽运掺Er光纤产生驻波饱和效应，在1.55m波长处形成42nm激光输出，输出功率大于3.5dBm，功率稳定性优于士0.005dB。

孩子们在向电视调谐中会被编程为主要的消费者。

We discovered it is possible to get two pairs of parametric output simultaneously by utilizing the"phasematching retracing behavior".

并提出利用调谐曲线中的&折返&现象，有可能同时获得两支参量输出。

With an electronic guitar tuner with only 6 intervals, find on your transposing chart the steps for each string that are tuned to E,A,D,G, or B and use these intervals to set transposing feature.

一个只有6间隔电子吉他调谐器，找到您移调为每个图表都调整到E，A，D和G或B和利用这些时间来设置字符串移调功能的步骤。

You should make sure your wheels are not spinning and if it does so, contact your auto mechanic and get it tuned.

你要肯定你的车轮不转动，如果它这样做，你接触汽车和机械得到调谐。

It's not super bad, but much like tuning a car to get better gas mileage, it's one place where you can drop some of the weight and make the machine run a bit better.

它不是超级坏，但很像调谐汽车变得更好气体里程，它的一个地方，您可以减少一些重量和使机器运行1位更好。

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）。
