Researchers have now found every particle predicted by the model, save one: the Higgs boson, theorized to help endow other particles with mass.
研究人员现在找到了模型预测的每一个粒子,并将其中一个保存下来:希格斯色子(Higgs boson)从理论上帮助赋予其他粒子以质量。
Although the Standard Model requires only one Higgs field to generate all the elementary particle masses, physicists know that the Standard Model must be superseded by a more complete theory.
虽然标准模型只需要一个希格斯场,就足以产生所有基本粒子的质量,可是物理学家知道,标准模型一定会被更完备的理论所取代。
A one-dimensional unsteady model was developed to simulate the trapping of fine particles by a wall-flow filter by simulating the flow field and particle layer distribution in a channel.
