By concentrating the energy in space and time, the laser produces positrons more rapidly and in greater density than ever before in the laboratory.

通过在空间和时间上集中能量，激光比之前实验室更快更多地制造出了正电子。

If we think of the size of a typical atom, we would say that would be about 10 to the negative 10 meters. So, we can see the diameter of a nucleus is absolutely smaller really concentrating that mass into a very small space.

一个普通细胞的大小，抱歉，我和细胞核搞混了0,如果我们考虑，一个普通原子的大小,这大概是10的负十次方米,所以原子核的直径确实非常小,真的是把质量。
