计时

And chronometric instruments.

物品，珠宝，首饰，宝石，钟表和计时仪器。

The volunteers could decide at their own pace, but they had to report the moment of the conscious choice based on a clocklike device in the scanner.

被试者可以根据个人习惯掌控做出选择的时间，但必须向扫描仪中计时器报告他们意识到选择的时间。

As one VC who spoke at Y Combinator said,"Once you take several million dollars of my money, the clock is ticking."

一个风投曾经说过，&一旦你从我这拿了几百万的资金，那么计时就开始了。&

Analyzing the changing rule of reaction time under road lighting level of different lighting sources can ascertain the luminance contrast coefficients of different lighting sources to high pressure sodium lamp, then appropriate lighting source can be selected based on these coefficients during road lighting designing, road lighting could achieve the aim of safely, quickly, cozily run and energy saving.

分析不同光源在道路照明水平下的反应时间变化规律，可以确定不同光源对高压钠灯的亮度对比系数。在进行道路照明设计时，就能选择合适的照明光源，使道路照明进一步达到安全、快速、舒适和节能的目的。

In this example live daphnia are placed in the water droplet, their heartbeats can be picked up as a signal and used as a beat, a timer, a metronome

这里的例子，将活的水蚤放入液态镜片中，侦测到的水蚤的心跳，当做一个数位讯号，转换为音乐中的节拍、计时器、节拍器等等。。。。

Both kinds of algorithms can improve the static and dynamitic characteristics of the system, and meet the design requirements.

在进行系统整体设计和软、硬件设计时，本文充分考虑了系统的实际工况，设置了手柄信号中位死区，以消除系统的误动作；同时，为适应比例阀的工作频率，利用单片机对PWM输出信号进行了分频处理，保证了通过比例阀的平均电流值不变。

Part II:The electrocatalytic oxidation of guanine, adenine, guanosine-5'-monophosphate and ssDNA was performed in the presence of iron bis(2,2':6',2"-terpyridine) and Fe tris(1,10-phenanthroline) complexes as a homogeneous catalysts with Fe redox couple. The electrocatalytic and electroanalytic properties of guanine with an iron bis(2,2':6',2"-terpyridine) complex was measured by the amperometry method using the rotating disk electrodes. Electropolymerization of iron tris(5-amino-1,10-phenanthroline) complex produced thin polymer films on a gold, platinum, nickel, and glassy carbon electrode.

第二部分利用iron bis(2，2'：6'，2&-terpyridine)和Fetris(1，10-phenanthroline)之金属错合物当作均相的催化剂对於鸟嘌呤、腺嘌呤、5'-鸟嘌呤核苷单磷酸盐(guanosine-5'-monophosphate)和单股DNA进行电催化氧化的研究。iron bis(2，2'：6'，2&-terpyridine)之金属错合物对於鸟嘌呤的电催化和电分析性质可利用计时安培法并使用旋转环-碟电极进行测量。rontris(5-amino-1，10-phenanthroline)之金属错合物可经由电聚合过程所形成的聚合薄膜固定在黄金、白金、镍和玻璃碳电极上。

Take Pb〓 as an example, its detection limit is 8×10〓mol/L. The research on mechanism of this method shows that these achievements was caused by the characteristics of silver disc electroxidation and electroreduction and ACOC.

对该法的机理做了较深入的探讨，表明该方法灵敏度高、稳定性重现性好的原因是银盘电极的氧化还原性质和交流示波计时电位法的特点共同所致。

"I still can't believe you didn't tell us about it," said Ron grumpily.

你竟然不告诉我们有关计时器的事，我仍旧不能相信。

The gear discussed in this text is the horological gear. Gear is the indispensable component of the mechanical watches, whose performance determines the accuracy of the timing of the watches.

中文摘要本文所研究的是机械钟表中的齿轮，齿轮是机械钟表中不可缺少的重要组成部分，其性能直接决定了钟表计时的准确性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
