把这一句，留给此刻的你

Direction coupling between the various radiations generated in a nuclear reaction both with one another and with the initiating radiation can also be detected and measured by coincidences; this provides valuable information about the structure of the atomic nuclei.

在核反应中产生的各种辐射相互之间以及与初始辐射之间的方向耦合也可以用巧合来探测和测量;这提供了有关原子核结构的有价值的信息。
