top quark meaning in English
【物理学】顶夸克〔基本粒子之一〕。
Examples
- It predicted the existence of the w and z bosons , the gluon and two of the heavier quarks ( the charm and the top quark )
它预测了w玻色子、 z玻色子、胶子以及两种较重的夸克（魅、顶夸克） 。 - For example , the analysis of precision measurements of w and z boson properties led to the accurate prediction of the top quark mass before the top quark had been directly produced
举个例子，在以实验直接制造出顶夸克之前，我们就已经藉由分析w与z玻色子相关性质的精密测量，而精准预测出顶夸克的质量。
