The calculated results show that the total differential cross section is the general rule and characteristics of collision between an atom and a diatomic molecule, the phenomenon of the scattering oscillation at large angles is more evident along with increase of the incident energy for low-lying rotational excitation state-to-state differential cross sections in He-BH collision system.

计算结果表明：He-BH碰撞体系的总微分截面具有原子与双原子分子散射的一般规律和特征；随着入射能量的增加，低转动激发态-态微分截面在大角区的散射振荡现象会更加明显。

One of the halogens, it is a deep red, fuming liquid at ordinary temperatures (freezing point 19 F [-7.2 C]; boiling point 138 F [59 C]) that contains diatomic molecule s (Br2), and it does not occur free in nature.

是一种卤素，深红色，常温下以发烟液体形式存在(熔点︰-7.2℃〔19℉〕。沸点︰59℃〔138℉〕)。溴的液体和气体分子都含有两个原子(Br2)，仅以溴化物形式存在。

Basically, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2) and that energy will be released in the process.

This dissertation is concerned with the kinetics of the nonequilibrium dissociation and ionization of gases that are significant in the high temperature gas dynamics. There are two parts in the dissertation. In the first part, the kinetics of dissociating gas, a theoretical calculation is made of the nonequilibrium dissociation of the diatomic molecule behind a strong shock wave front.
