长信号

Since the float-zone silicon has lower contaminations and longer minority carrier lifetime than those in Czochralski Silicon and other semiconductor material, it has potential advantages to fabricate phototransistor on high-purity FZ silicon substrate to achieve a high gain at ultra low signal levels.

区熔单晶硅与直拉单晶硅以及其他半导体材料相比杂质含量少，少子寿命长，所以以区熔单晶硅为衬底制作的光晶体管在弱的光信号下仍然有高的增益，适宜于弱光探测。

It can be used in studying the calcium dynamics, in addition it\'s applicable for real-time, less damage and long-playing observation. It might be important to study calcium of spine with stimulations of neurotransmitter and action potential.

结果表明，利用Cameleon 的FRET 比值变化来定量监测树突棘钙动力学的方法是切实可行的，并可以进行实时、无损、长时间的监测，为研究神经递质、动作电位等刺激对树突棘内钙信号影响提供一种重要研究手段。

In some fields which require accurate measurements, such as the signal measurements of inertial guidance system, there are a lot of inconvenience for workers using counter to measure frequency, such as long time, numerous steps of changing channels.

在某些对测频精度要求较高的场合，如惯导系统的信号测量，人工采用计数器测频法存在着耗时长、更换通道步骤繁琐、测量不方便的缺陷。

Because both insulin and leptin levels are low in this type of diabetes, the long-recognized syndrome of 'diabetic hyperphagia'27 could potentially result from reduced CNS signalling by insulin, leptin, or by both hormones.

由于胰岛素和leptin水平是低在糖尿病的这个类型，长被认出的综合症状'糖尿病hyperphagia' 27可能潜在地起因于发信号由胰岛素， leptin，或者由两激素的减少的CNS。

The selection part (107) selects, based on the retransmission information inputted from the control part (101), a transmission signal into which a longer guard section has been inserted as the number of retransmissions has become larger.

选择部(107)根据从控制部(101)输入的重发信息，选择随着重发次数的增加而插入更长的保护区间的发送信号。

Omega, the Swiss watch company now timing its 23rd Olympics, has installed 420 tonnes of equipment, including almost 400 scoreboards, 175km of cabling and 65 television generators.

瑞士手表公司欧米茄，现在是第23次为奥运会计时。它安装了420吨重的设备，包括近400块记分板、175千米长的电缆以及65台电视信号发生器。

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％。
