Abstract: An event simulation generator from differential cross section formula is described certain high energy physics process, which.includes the integral of final state phase space, and the generation of final particles' four-momentum. For the commonly used stratified and importance sampling method, their individual characteristics, application domain, operating procedure and skills are discussed in detail, their advantages and disadvantages as well. Finally a Bhabha event generator established for LEP/SLC energy range is introduced.

Key words: event simulation generator, stratified sampling method, importance sampling method, Bhabha scattering
