夸克是组成质子和中子的最基本粒子,但夸克只有一种吗?它是否还可以再分下去了呢?我们为什么看不见单个夸克?在宇宙中有没有自由夸克?有关夸克的深层奥秘还需要科学家进一步探索。而夸克也还只是基本粒子的一种,令人眼花缭乱的基本粒子家族都有哪些不同和相同之处呢?
The quark is the most basic particle that makes up protons and neutrons, but is there only one kind of quark? Is it still possible to divide it again? Why can’t we see a single quark? Is there a free quark in the universe? The deep secret about quarks is also Need scientists to explore further. And the quark is still just a kind of basic particles, what are the differences and similarities in the dazzling array of elementary particles?
