Protons are a kind of hadron, hadrons are really heavy particles.

质子子一种，子很重粒子。

Unfortunately hadrons, such as protons and antiprotons, are made of smaller bits called quarks.

不幸，子，比如质子和反质子，由名夸克更小单元所组成。

As a result, hadron collisions can be messy and difficult to interpret.

结果，子撞击可能造成混乱且难于预测局面。

Both laboratories use similar approaches: smashing particles called hadrons into each other.

将称作子高能粒子彼此对撞。

This machine, which collides packets of high-speed protons (examples of a type of subatomic particle called a hadron) was switched on again on July 5th, after a three-and-a-half-year upgrade, for what is known as " Run 3" .

这台碰撞高速质子包（ 一种称子亚原子粒子例子） 机器在三年半升级后于 7 月 5 日再次启动，所谓“ 运行 3" 。
