摘　　要：随着EGS在辐射物理和医学物理等众多方面的广泛应用,其物理内核被EGS开发小组所不断更新,光子的输运模型也越来越完善。本文综述了光子输运模型的进展,包括线性极化光子散射、康普顿散射中的电子约束等效应以及光子截面数据库的更新。With the wide application of EGS in radiation physics and medical physics, the inner physics model is perfected by the research group of EGS. A review of the recent improvements of photon physics model is presented. The effects such as the linearly polarized photon scattering and scattering are introduced as well as the updates of the photon cross section library. binding in Compton scattering are introduced as well as the updates of the photon cross section library.
