Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

Beijing Institute of Technology, Beijing 100081,ChinaIn order to get the high output power, a RF excited diffusively cooled all-metal slab waveguide CO2 laser was reported, in which gas discharge region was constructed by two aluminum side walls and aluminum electrodes. The region dimension was 2 mm height×20 mm width×386 mm length, and the gas composition was CO2:N2:He:Xe=1:1:3:0.26. This technique replaced the old ceramic and metal sandwich waveguide technique.The optimum out power 127 W was achieved from the RF excited diffusively cooled all-metal slab waveguide CO2 laser with the longitudinal voltage uniformity distribution technique and scaling area technique. The electro-optic conversion efficiency was about 14%.

为了获得较高的激光输出功率，介绍了射频激励扩散冷却全金属板条波导CO2激光器，放电区域由左右两个铝合金壁和上下两个铝合金电极构成，放电区域高2 mm，宽20 mm，长386 mm，工作气体混合比CO2：N2：He：Xe=1：1：3：0.26，该技术代替了过去的金属陶瓷结构，结合纵向电压均匀分布技术和面增比技术，获得了127 W的激光输出功率，光电转换效率高达14%。

Accordingly, when the novel re-propagating HIVs start to pullulate, their gp120 must be appeared on the surface of host cells. Then,gp120 must be bound by XE in XE-TNFαm2, and latter's killing signal must be transduced into cells.

据此，当重新繁殖的HIV开始出芽时，其gp120必然出现在宿主细胞表面，且此gp120必然被XE-TNFαm2中的XE所结合，并其TNFαm2的杀伤信号将转导进入细胞。
