The method includes acquiring with the frequency meter the tested clock signal and measuring its frequency; sending the tested frequency value to the data acquisition and processing module for calculation and processing regularly; and processing the frequency data comprehensively in the data processing output module and displaying output figure and historical data.

所述的方法包括：首先，频率计采集待测时钟信号，并测试其频率值；然后，频率计定时将测试得到的待测时钟信号的频率值发送给数据采集处理模块进行计算处理；最后，数据输出处理模块对接收数据采集处理模块处理后的频率数据进行综合处理，并将获取的图形数据和历史数据显示输出。

There are three buttons mounted on the casing, namely two big ones on each side of the clock and the clock winder itself.

有三个按钮安装在套管，即两个大的每一方的时钟和时钟发条本身。

In 1989, we familiar to ear 80486 chipses be released by the INTEL, the great place of this kind of chip lies in the boundary that it broke 1,000,000 transistors actually, integrating 1,200,000 transistors.80486 clock frequencies raise a 33 MHzs, 50 MHzs gradually from the 25 MHzs.80486 is 80386 help processor with mathematics,80387 and 1 high speed of 8 KBses saves an integration slowly in a chip, and in the 80 X86 the serieses for the very first time adopted a RISC technique, can carry out an instruction in a clock period.

1989年，我们大家耳熟能详的80486芯片由INTEL推出，这种芯片的伟大之处就在于它实破了100万个晶体管的界限，集成了120万个晶体管。80486的时钟频率从25MHz逐步提高到33MHz、50MHz.80486是将80386和数学协处理器80387以及一个8KB的高速缓存集成在一个芯片内，并且在80X86系列中首次采用了RISC技术，可以在一个时钟周期内执行一条指令。

The clock is the world's largest four-faced, chiming clock and the third largest free-standing clock tower in the world.

时钟是世界上最大的四个面，钟声时钟和世界第三大自由独立的钟楼。

This CPU works at 2.16GHz nominal clock speed and 13x clock frequency multiplier.

这中央处理器工程名义为2.16时钟速度和13 x的时钟频率倍增器。

Additionally, the author proves the fact that the coordinate differential is embodied in hyperbola intersecting algorithm. 3. Time measurement Based on GPS Time System The basic observation for UGPS is the time that acoustic signal arrives at GIB. To measure the time difference, the time system of every GIB should be synchronized as all GIBs are working independently.

要测量时间差值，必须要求各个浮标系统的时钟严格同步，本文采用了基于GPS时间系统的浮标时钟同步，同时通过GPS接收机的1PPS脉冲校正延时测量漂移，实现精密的时间测量方法。

假定fsck没有遇到任何问题，它就马上装载你的文件系统：在其它任何进程启动之前，你的CMOS时钟必须调整为内核时钟可以理解的形式：然后整理var目录，将引导信息写入dmesg.boot： if ！

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
