AI中文摘要：
在透射电子显微镜中，电子主要通过声子激发发生非弹性散射，这一过程被称为热漫散射。为了捕捉非弹性散射对弹性散射分量的影响，电子传播的建模必须包含吸收效应，以解释电子束弹性通道的逐渐损耗。目前存在多种模拟该吸收的方法，本文将广泛使用的复吸收势方法，与基于关联原子运动及爱因斯坦原子运动模型的更精细的冻结声子模型进行了比较。
英文摘要：
In transmission electron microscopy, electrons undergo inelastic scattering primarily through phonon excitations, known as thermal diffuse scattering. To capture the inelastic scattering effects on the elastic scattering components, absorptive effects must be included in the modeling of electron propagation, accounting for the gradual depletion of the elastic channel of the electron beam. Several approaches to modeling this absorption exist. In this paper, we compare the widely used complex absorptive potentials method to the more elaborate frozen phonon model, based on correlated atomic motion and on the Einstein model of atomic motion.
