Optical atomic clocks oscillate much faster, at about 500, 000 billion cycles per second, and thus divide time into smaller units.
光学原子钟振动的速度快得多，大约每秒500万亿次，因此把时间分成了更小的单元。
The height of the wave from the lowest to the highest point is its amplitude. The number of cycles per second is the wave's frequency.
从波形的最低点至最髙点的高度是它的幅度，每秒钟周期的数量是波的频率。
The speed of a computer is usually expressed in cycles per second. Typical machines operate at100 to200 megahertz or100 million to200 million cycles per second.
计算机的速度通常用每秒(行)(钟)期来表示。典型的机器运转在100到200兆赫或者说每秒100到200兆周期。
The coding used to impress information on the wave can be a function of the frequency (the number of waves or cycles per second) or amplitude of the waves or cycles.
对载波中的信息进行压缩的编码方式可以是载波或周期的频率调制或振幅调制。
The time taken to complete one cycle is called the period, and the number of cycles per second is the frequency; the maximum value in either direction is the current's amplitude.
完成一次循环的时间称为周期，每秒循环的次数称为频率，任一方向的最大值称为交流电的振幅。
As the doohickey hummed away at a very high frequency-a whopping 6 billion cycles per second-the "piezoelectric" material in it produced a warbling electric field that was easy to detect.
当这个小装置以每秒60亿周的高频速度振荡时，它表面的“压电”材料会产生一个很容易被检测到的振动电场。
While devices like the NIST-F1 use atomic signals of microwave frequency with billions of cycles per second, newer clocks, including Oates’, rely on light waves beating a million times faster.
诸如NIST-F1的仪器运用的原子信号是频率为数十亿赫兹的微波，新式时钟包括奥茨的都是运用频率快上百万倍的光。
Ac Alternating current (ac) is electric current that alternates between a positive maximum value and a negative maximum value at a characteristic frequency, usually 50 or 60 cycles per second (Hertz).
