机器每隔约100秒发送1个反质子脉冲进入到冷的氦气中。

The machine sends pulses of antiprotons about every hundred seconds into cold helium gas.

物理学家曾指出，用来生成中微子的质子脉冲，它在离开欧洲核子研究中心时约有10.5微秒长的持续时间。

Physicists had pointed out that the proton pulses that were used to generate the neutrinos that left CERN were of quite long durations, at 10.5 microseconds.

因此，OPERA团队使用了比上一次短3,000倍的质子脉冲来重复他们的实验，这样就会大大提高了中微子开始行驶时间的精确度。

Thus, the OPERA team repeated their experiment using proton pulses that were 3, 000 times briefer than last time, giving greater precision to the start time of neutrinos.
