The X-ray pulses have a shutter speed of less than 100 femtoseconds (100 femtoseconds = 1/10 of a trillionth of a second).

这种X光脉冲快门速度不到100飞秒（100飞秒= 万亿分之一秒的1/10）。

Inless than a trillionth of a second, water molecules are thought tofluctuate between the two states as the hydrogen bonds break and reform.

水分子的氢氧健一秒钟之内就会发生万亿次的断裂和重组。
