The results are as follows:1 No significant difference in the translational energy distributions for different CO rotational state products has been observed at 208nm and 213nm excitation wavelengths.

主要结论如下：(1)光解碎片CO 在208nm、213nm 两个解离波长下不同振转态的平动能分布没有明显地差别，而其不同振转态的各向异性参数β却有明显地不同。

Product translational energy distribution and angular anisotropydistribution for the CH_2 product from CH3 photodissociation at differentvibrational levels via the 3s Rydberg state have been measured.

We mainly detected the TOF and angular distribution of photofragment, and get the anisotropy parameter β and the translational energy distribution. In addition, we calculated the geometries of the ground states, the excited states and the triplet excited states, and the transition electric dipole moments.

主要是探测了光解碎片的时间飞渡谱和角分布并通过前向卷积方法拟合得到了各向异性参数β和光解碎片的平动能分布；此外还用从头计算方法计算了反应物分子的基态、激发态、三重激发态的平衡几何构型和分子的跃迁偶极矩并据此计算了一部分分子的解离态寿命。

The N + OH reaction system has no energy barrier in the entrance channel on the PES; instead, there are double wells along the reaction path, which leads to that the integral reaction cross sections are not strongly dependent on either translational energy or initial rotational and vibrational state.

计算还显示，由于N+OH反应入口谷没有能垒，而沿着最小能量反应路径有两个势阱，因此反应的积分截面并不强烈依赖平动能和反应物分子的初始振转态。

The mechanism studies on the atomic oxygen effects over surface materials become rather difficult due to the fact that the interaction, stemming from a highly complex environment in LEO, where the atomic oxygen are equipping with high translational kinetic energy and strong oxidizing characteristics, may induce complicated physico-chemical processes.
