摘　　要：长期受实验支持的标准模型,它的某些基本原理最近已受到实验事实的责难.如:EMC组发现的EMC效应;CLEO组发现的味变中性流夸克转换过程;CDF组发现夸克有结构的迹象及HERA的HI和ZEUS机发现的-l-q共振预示可能存在更深层次的物理;超神冈实验指出中微子有质量、混合和振荡;多家实验发现光子的夸克/胶子结构,轻子有"反常磁矩"等.这些实验事实都背离了标准模型的基本原理,对其重新审视是必要的.Some prime principles of the standard model of the elementary particle which have been supported over a long period of time have incurred censure recently from experimental facts,for example,EMC effect found by EMC group,the conversion process of flavor-changing neutral currents of a quark discovered by CLEO team,indications that a quark has structure by CDF group and l——q resonance by machines HI and ZEUS of HERA which may mean deeper and further physics there,a neutrino having mass,mixedness and oscillati...
