Scientists believe that gravity, electromagnetic force, strong nuclearforce and weaknuclearforce are the Four Basic Forces of the universe.
科学家们认为,万有引力、电磁力、弱力和强力是宇宙中的四种基本作用力。

Only gravity and a phenomenon called the weaknuclearforce, which governs some types of radioactive decay, can bind them—hence the term “weakly interacting”.
只有重力和一种可以支配某些放射性衰变的弱核力能够使其聚集凝固,“弱反应”这一术语由此得名。

By calling them “weakly interacting”, physicists mean that the particles experience another of the four fundamental forces, namely, the weaknuclearforce that is responsible for radioactive decay.
