在讨论原子级别时间的时候，物理学家用起皮秒（百万兆分之一秒）甚至飞秒（千万亿分之一秒）来都没任何不便。这是一方面。
Physicists have no trouble using, on the one hand, picoseconds (trillionths of a second) or even femtoseconds (quadrillionths of a second) to discuss time at the atomic scale.
数以兆计的中微子在每一秒都穿过你我的身体，却没有留下任何可辨识的踪迹。
Trillions pass through everyone's body every second leaving no discernible trace.
全功率运行时，数兆的质子在大型强子对撞机的加速环中加速，一秒钟可绕行11245圈，速度达到光速的99.99%。
At full power, trillions of protons will race around the LHC accelerator ring 11, 245 times a second, travelling at 99.99 percent the speed of light.
版本 1.1最大传输速度为12Mbit/s（兆比特/秒），而版本 2.0支持最高达 480 Mbit/s的传输速度。
Version 1.1 has a maximum transfer speed of 12 Mbit/s (megabits per second), whereas version 2.0 supports transfer speeds of up to 480 Mbit/s.
最新一代的WIFI技术（802.11n）一秒钟能传递160-300兆位的信息。
The latest version of Wi-Fi (802.11n) shuttles data at 160 to 300 megabits a second.
这种飞秒激光脉冲持续兆分之一秒(千万亿分之一秒)的时间，但是在其短暂的持续时间内，功率峰值可以达到北美电网功率相当的水平。
A femtosecond laser pulse lasts on the order of a quadrillionth of a second but reaches a peak power equivalent to that of the entire power grid of North America during its short burst.
光以太网可以跨越地区提供极高的带宽——100兆位/秒、1吉位/秒，甚至更高，而其价格与今天的1.5兆位/秒的T-1线路相当。
The Optical Ethernet can deliver very high band width-100M bit/s, 1G bit/s or even higher-across districts and counties, at prices similar to today's 1.5M bit/s T—1s.
