摘　　要：The standard model(SM)in particle physics has been successfully tested by the present experimental observations.The SM consists of electroweak unification theory and quantum chromodynamics(QCD)theory with light quarks(u;d;s)and heavy quarks(c;b;t)as its fundamental components.Usually,these quarks are named as the light flavor and the heavy flavor.In addition to quarks,there are intermediate gauge bosons and gluons for mediatingThe standard model （SM） in particle physics has been successfully tested by the present experimental observations. The SM consists of electroweak unification theory and quantum chromodynamics （QCD） theory with light quarks （u, d, s） and heavy quarks （c, b, t） as its fundamental components. Usually, these quarks are named as the light flavor and the heavy flavor. In addition to quarks, there are intermediate gauge bosons and gluons for mediating the electroweak and strong force, respectively. The heavy-flavor physics consisting of the charm c, bottom b, and top t quarks has been studied from heavy mesons and baryons whose properties are mainly determined by the c and b quarks in the bound state, such as B mesons and D mesons in the heavy-flavor factories （B factory and charm factory）.
