The measurement amounts to the neutrinos travelling faster than the speed of light by a fraction of 20 parts per million.
这些测量结果意味着中微子的速度要比光速快五万分之一。
All the methods give the same result: the concentration of oxygen is declining everywhere at the same rate, about 20 parts per million (PPM) per year.
所有这些方法都得到了同样的结论:地球上所有地方的含氧量正在以同样的速度(大约每年0.002%)减少。
