So it emits phased muon particles.

它会阶段性放射出定相μ介子。

Thus, you emit 180 anti particles per hour in about 4,000 per day.

因此，你每小时释放一百八十个反粒子，每天大约四千个。

This posits that black holes can emit tiny particles, causing them to lose energy, shrink, and ultimately vanish over colossal time scales.

这假设黑洞可以发射微小粒子，导致它们失去能量、收缩，并最终在巨大的时间尺度上消失。

For example, if the parent nucleus is radium, it would decay into radon and emit a single alpha particle.

例如，如果母核是镭，它会衰变为氡并发射单个 α 粒子。

To my great surprise, I found that the black hole seemed to emit particles at a steady rate.

使我大为吃惊的是 我发现黑洞似乎以稳定的速度发射粒子。

Often accretion disks are accompanied  by relativistic jets, which emit even higher energy particles and radiation than  from the accretion disk.

吸积盘通常伴随着相对论性喷流，它们发射出比吸积盘更高能量的粒子和辐射。

Plus, the bigger the nucleus, the more energy there is in each of the emitted alpha particles – which the researchers can also measure.

另外， 原子核越大，每个发射的 α 粒子中的能量就越多——研究人员也可以测量到这一点。

Back in the 1970s, physicist Stephen Hawking worked out the math of black holes combined with quantum mechanics, and discovered that under some circumstances they can emit particles.

早在20世纪70年代，物理学家斯蒂芬·霍金结合量子力学计算出了黑洞的数学，并发现在某些情况下它们可以释放粒子。

As black holes lose mass, they emit particles and energy faster, so each time one evaporates completely it'll emit a flare of light like a small bomb going off.

当黑洞失去质量时，它们释放粒子和能量的速度会更快，所以每当一个黑洞完全蒸发时，它就会释放出一束光，就像一颗小炸弹爆炸一样。

How is it possible that a black hole appears to emit particles when we know that nothing can escape from within its event horizon?

当我们知道黑洞的事件视界内没有任何东西可以逃脱时，黑洞怎么可能会发射粒子？

The second type of decay that can occur is beta decay, when an unstable nucleus emits a beta particle, which is just an electron.

第二种可能发生的衰变是 β 衰变，当不稳定的原子核发射出 β 粒子时，它只是一个电子。

Contrary to the accepted view at the time that nothing could escape from a black hole, Hawking proposed that black holes could emit particles, a phenomenon now known as Hawking radiation.

与当时公认的没有任何东西可以从黑洞中逃逸的观点相反，霍金提出黑洞可以发射粒子，这种现象现在被称为霍金辐射。
