英语语法分析

We shall see later that gluons are essential to the dynamics of the quarks inside the proton.

后面将会看到，胶子对于质子内夸克的动力学机制来说是必需的。

The quarks and gluons slowed down so much that some of them could begin sticking together briefly.

夸克与胶子的速度越来越慢，于是有些粒子开始能短暂地黏聚在一起。

This indicates that the conclusion on gluon jets being "fatter" than quark jets is valid only for hard gluons.

这表明，只是对于较硬的胶子，胶子喷注比夸克喷注“胖”的结论才能成立。
