本文提出了一个模拟直周期和弯周期原子结构中取向效应的模型。采用连续势近似。该模型允许通过直线和弯曲晶体操纵粒子轨迹，并缩放有通道粒子的强子和电磁过程的横截面。根据这一模型，开发了Geant 4工具包的扩展。该代码已被验证对数据的通道实验在欧洲核子研究中心进行。
A model for the simulation of orientational effects in straight and bent periodic atomic structures is presented. The continuum potential approximation has been adopted. The model allows the manipulation of particle trajectories by means of straight and bent crystals and the scaling of the cross sections of hadronic and electromagnetic processes for channeled particles. Based on such a model, an extension of the Geant4 toolkit has been developed. The code has been validated against data from channeling experiments carried out at CERN.
