At 86.6% of the speed of light, the Lorentz factor is 2, meaning time will pass twice as slowly aboard the spaceship.

当速度为光速的 86.6％ 时，洛伦兹因子为 2，意味着飞船上的时间慢为原来时间的一半。

This relationship can be quantified with something called the Lorentz factor, which is defined by this equation.

这种关系可以用洛伦兹因子来量化，这是洛伦兹因子的定义公式。
