For example,speaking 555 timer flakes and intergrated operate amplifier CA3140 to control,it is a normal thing that the timer is coming out,But today this timer adopt 555 timer oscillatory circuit as at time base signal pulse input,choise magnificated intergrated flake CA3140 to manger ,make the timing of 555 steady state time lagmay be increase one hundred multiple.

由于集成块集成度高，功能强，功耗低，速度快，价格便宜，实用灵活，开发周期短等优点，从上个世纪开始，随着各种各样的集成芯片的问世，比如说555定时器芯片和CA3140集成运算放大器芯片，定时器的形成已经是很普通的事情，但今天这个定时器采用555定时器振荡电路作为时基信号脉冲输入，选择可放大的集成运算放大器3140控制器，使555的稳态延时范围可以增加100倍。

The Yankees twice wasted opportunities with the tying run 90 feet away. Derek Jeter legged out a one-out triple in the sixth, but was left on third base, as Jackson got Bobby Abreu to ground out and induced Matsui to pop weakly to shortstop. In the seventh, Shelley Duncan pinch-hit and struck out looking to pin Cabrera in scoring position.

洋基浪费了两次追平分只在90呎远的机会，6局时基特一出局时跑出一支三垒安打结果却留下残垒，因为Edwin Jackson让阿伯滚地球出局而松井只击出游击方向的软弱小飞球，而第7局代打的雪莉站著被三振让牛奶只能钉在得点圈上。

According to the character of power system, this paper analyzes the digital spectral structure and representation of a sampled periodic signal and discusses the influence to the A.

但是，这种采样技术由于时基不准确，造成的各路A/D之间存在着不容忽视的延时误差，因此必然存在着非均匀采样现象。

It is found that for a certain mode-locked solid-state laser with a pulse profile of sech2(1.763t/τ),the jitter is approximatively a linear function of the net group delay dispersion,and turns to be larger with increasing GDD ;however,it cannot be reduced to zero even if the GDD is completely compensated.

结果表明：对于一台脉冲轮廓为sech2(1.763t/τ)的确定的锁模固态激光系统，时基抖动近似为净群速延迟色散的线性函数，且随着GDD的增加而变大；然而，即便在GDD被完全补偿的情况下，时基抖动也不会是零。

Aimed on this research theme, this thesis studies some key issue of nonuniformly signal sampling theory and its application.

随着高速采样技术发展，对非均匀采样信号的研究也成为信号处理领域的一个重要研究内容，如何提供更精确的采样时基，或者是如何对采样时基进行校正，以及利用已知的时基偏差，对采样信号进行重建，已成为在工程应用中一个重要组成部分。

Dly timebase on a scope is very useful once you figured out when, why and how to use it.

示波器上的时基延时非常有用；一旦你知道什么时候使用，为什么使用，怎么样使用时基延时的时候。

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％。
