The Mazhashan syenites in the Bachu area were formed in the Late Permian with the zircon SHRIMP age ranging from 286 to 277Ma, and these ages are consistent with the ages (300-260 Ma) of the post-collisional granites in the southern Tianshan orogen.

In view of the methods of generating and detecting 〓 radicals, we have built up an experimental set-up of the pulsed dc discharge combined LIF technique, by which we have studied the collisional quenching of electronically excited 〓 radicals by various quenchers.

采用对〓／Ar混合气体脉冲直流放电的方法获得了生成稳定且数密度足够的〓自由基；解决了直流放电过程中产生的其它碎片对〓自由基的LIF信号干扰的问题。2。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

对实验结果的分析表明，电子激发态NCO A〓Σ〓（00〓0）的猝灭过程可能属于多极吸引势起着重要作用的入口通道控制机制，对于大多数被研究的猝灭剂分子，化学反应在其对NCO自由基的猝灭过程中可能起着重要的作用。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

这一加成过程是一个入口势能面属于纯吸引型的无垒过程，故是NCO+O反应的主要通道。二是O原子攻击NCO分子的O原子得到中间物tran-NCOO，再通过C-O键的断裂生成产物CN+OO。该产物通道由于是吸热的，故很难发生。

However, for the collision processes in He target, a large discrepacy between the CTMC results and experimental measurement is found. As is well known, the microcanonical distributions of bounded electrons in CTMC method is quite different from quantal distributions, we modified the initial microcanonical distribution by using eleven different ionization thresholds of electron bounded in target. With modification, we calculated the collisional process of O~(3+) with He, and the total cross sections of all processess are calculated as a function of the incident energies. The agreement with experiments is improved by the modified distributions.

但由于靶电子的微正则分布与量子分布有很大不同，在计算离子与He靶碰撞时发现结果与实验差距很大，我们基于使用多个系统总能量U值，对初始电子的微正则分布进行了优化，使其更接近于量子力学的径向空间分布，然后计算了O~(3+)与氦原子随入射离子能量变化的各种反应过程截面，发现优化极大地提高了计算精度，特别是我们的模型对于描述单电子、双电子丢失过程非常成功。

The is related to the frequency dependent absorption cross section and the density and spatial distribution of atoms in the lower level of the transition. Position dependent 5P3/2 state densities had been combined with the collisional broadening rate 5P3/2 5S1/2 line due to both helium and cesium perturbers to yield the .The effective radiative rates of the Rb D2 line as a function of the He pressure PHe were obtained . The fluorescence intensity I780 of the 5P3/2 5S1/2 emission was measured simultaneously.

由于辐射陷获存在，有效辐射率是自然辐射率与透射因子（发射的光子在探测区域内没有被吸收的平均概率，它与吸收截面及激发态原子密度和空间分布有关）的乘积。5P3/2原子密度及其空间分布结合5P3/2 5S1/2跃迁线的碰撞增宽计算了透射因子，从而得到了不同He气压下，Rb D2线的有效辐射率。

The Motagua fault, the central active strand of the suture zone,underwent two major collisional events within a system otherwise dominated by strike–slip motion.

在莫塔瓜故障，中央的缝合带活跃链，在经历了两个主要的，否则的走滑运动控制系统的碰撞事件。

The data show the following ages: 1894±17 Ma and 1847±59 Ma for garnet pyroxenite of the Tiantangshan Group complex, indicating a Paleoproterozoic age; 1462±28 Ma for the metabasic volcanic rocks of the Yunkai Group complex, indicating the presence of fragments of the Meso- and Neoproterozoic oceanic crust in the Yunkai area; 906±24 Ma for the granitic gneiss intrusion is, which should be the product of the global Grenville collisional orogeny occurring around 1000 Ma BP. In addition, an inherited detrital zircon age of 2702±13 Ma was also obtained, which is the oldest age in the Yunkai area and even in Cathaysia, proving the presence of Neoarchean continental crustal material in Cathaysia.

获得天堂山岩群石榴辉石岩的形成年龄为1894Ma±17Ma和1847Ma±59Ma，表明其时代为古元古代；云开岩群洋中脊型变质基性火山岩的喷发年龄为1462Ma±28Ma，证明该地区存在中元古代的古洋壳残片；获得花岗质片麻岩的侵入年龄为906Ma±24Ma，应为1000Ma前后发生的全球性Grenville期造山作用的产物，并获得2702Ma±13Ma的继承碎屑锆石年龄，这是云开地区乃至华夏古陆目前获得的最古老年龄，证明华夏古陆曾存在新太古代陆壳物质。
