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only one Higgs field to generate all the elementary particle masses, physicists know that the Standard Model must be superseded by a more complete theory.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.
