采用半经验的AM1量子化学计算方法和静态理论,分别考察了噻吩、 3 甲基噻吩和 2 ,5 二甲基噻吩分子结构特性的不同,从偶极矩、各自垂直于芳香环平面的二维电势能分布曲线和整个分子周围三维电势能分布情况等方面分析了它们在分子筛催化剂表面吸附速度的快慢和生成正碳离子稳定性的高低,进一步比较了噻吩及其衍生物所生成的正碳离子进一步反应的能量变化,从而可判断噻吩及其衍生物裂化脱硫速度的快慢,噻吩及其衍生物裂化脱硫的速度由大到小分别为:2 ,5 二甲基噻吩、 3 甲基噻吩、噻吩。

China has five notable FDI patterns that are substantially distinct from the patterns observed in the other countries or regions:(1) the highly reliance on FDI,(2) the paradox of the high deposit residues in the state-owned commercial banks and the continuingly large amount of FDI,(3) the small investment scale of FDI,(4) the extremely decentralized industry distribution of FDI, and (5) the concurrence of the nation-wide FDI popularization and imbalance of the FDI geography distribution.

在中国利用FDl的过程中,出现了一系列有别于其他国家和地区的独特现象,如:对FDI的过度依赖现象;高储蓄余额和巨额FDI并存的矛盾;PDI企业的平均投资规模低于中型企业的平均投资规模;FDI的行业分布的极端分散;FDI地理分布的不均衡性与普遍性的共存等。

The real-world joints in the aircraft structure usually consist of multi-row fasteners. This thesis builds the 3D FE contact analysis model of a typical aircraft joint with three-row countersunk screws, and studies pin-load distribution and stress characteristics under constant and varied cross-section thicknesses as well as with and without pre-tighten screw conditions for the joint. Many applied pin-load numerical distribution laws for different conditions in the joint are recognized.

This thesis has systematically studies the microstructure of the sinter bearing fluorine of different compositions and in different sintering condition.(1) The main units of the Low Fluorine Sinter are magnetite、hematite、 SFCA、larnite、glass and pore. The cuspidine doesn't form for the low content fluorine, and the fluorine is in glass; Sinter basicity dominates the forming of the larnite and SFCA, when basicity is between 1. 72 and 1. 96, there are more larnites in the binder phase, and when the basicity is biger than 1. 96, there are more SFCA in the binder phase; the hematite appears like magnetite and usually is around pore.
