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

不幸的是，强子，比如质子和反质子，是由名为夸克的更小单元所组成的。

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

结果，强子的击可能造成混乱且难于预测的局面。

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

将称作强子的高能粒子彼。

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" .

这台碰高速质子包（ 一种称为强子的亚原子粒子的例子） 的机器在三年半的升级后于 7 月 5 日再次启动，所谓的“ 运行 3" 。
