利用准经典轨线方法，研究了反应Li＋HF→LiF＋H和Li＋TF→LiF＋T的微分散射截面．结果表明Li＋HF反应微分散射截面是很强的前向散射分布，而Li＋TF反应微分散射截面呈现出前向和侧向两种优势分布．结合原子核间距随轨线传播时间的演化结果，可得出结论：反应Li＋HF→LiF＋H主要是直接反应机理，而反应Li＋TF→LiF＋T是直接与间接两种反应机理．

Differential cross sections （DCSs） of the reactions Li ＋ HF → LiF ＋ H and Li ＋ TF → LiF ＋ T have been investigated by employing the quasi - classical trajectory method. It was found that the DCSs dis- play a strongly forward scattering for the Li ＋ HF →LiF ＋ H reaction, but both the forward and sideways scatterings for the Li ＋ TF → LiF ＋ T reaction. Combining results of trajectories propagation along the time, it can be concluded that the Li ＋ HF →LiF ＋ H reaction is the dominantly direct reaction mechanism, while the Li ＋ TF → LiF ＋ T reaction undergoes both the direct and indirect reaction mechanisms.
