While we have received repeated assurances from the Chinese that they oppose the proliferation of WMD materials, technology, and their means of delivery, we remain deeply concerned by the proliferant activities of its various entities.

尽管中国方面多次向我们保证，他们反对扩散大规模毁灭性武器的材料、技术及其运载工具，但一些中国实体的扩散活动仍受到我们深切关注。

Finally, an example of proliferative process adjustment model validated that proliferative process adjustment model was feasible and effective.

最后，以一个实例分析了扩散工艺的调整过程，验证了扩散工艺调整模型的实用性。

Antibiotic susceptibility tests were carried out by K-B diffusion method on 41 vibrio strains isolated for one year both from farming seawater (18 strains) and digestion guts (23 strains) of the cobia, Rachycentron canadum . We chose 10 different species of antibiotics and refered to NCCLS performance standards for antimicrobial susceptibility testing, while taking Staphylococcus aureus ATCC25923 and Esсheriсhia coli ATCC25922 to control the test.

选用常用的10种抗生素，通过纸片扩散法（Kirby-Bauer纸片扩散法，简称K-B法），参照NCCLS抗生素敏感试验操作标准，并以金黄色葡萄球菌 Staphylococcus aureus ATCC25923和大肠埃希菌Esсheriсhia coli ATCC25922为质控菌株，对周年监测分离自养殖军曹鱼水体及肠道的41株优势弧菌（水体菌18株，肠道菌23株）进行了药物敏感性研究。

The results show that a sound bonded interface is obtained without sheet inclusion, pore and unbinding. The microstructure consists of bulk α-Mg phase and needle compound in the weld metal, element Al diffuses along the grain boundary of the substrate into the welding line. A little Y diffuses into the base metal. A little Mn and Cu segregate and element Ni distributes homogeneously and no segregation appears in weld area.

结果表明：界面接合良好，未观察到片状夹杂物、气孔及未焊合等缺陷；焊缝区由块状α-Mg相和针状化合物组成，基体中的Al元素通过晶界扩散偏聚到焊缝中，微量Y元素扩散到基体中，有少量的Mn和Cu元素发生偏聚，Ni元素分布均匀，没有发生偏聚现象。

Institute of Microbiology and Epidemicology, Academy of Military medical Science, Beijing,100071,China The performance of BL3 safety laboratory in preventing experimental aerosol diffusion and sterilizing microbe aerosols through high efficiency filter in a ventilation system was tasted.Aerosols of uranin, vibrio phage and Bacillus subtilis var. niger spores were used for the test.

P3级微生物安全实验室防气溶胶扩散性能的检测胡庆轩车凤翔摘要：采用荧光素钠、弧菌噬菌体和枯草芽胞杆菌气溶胶对P3级微生物安全实验室防气溶胶扩散性能及其排风系统中高效过滤器滤除气溶胶的效果进行了检测。

The first to appear was the sour or Seville orange, which was valued both as an ornamental plant and for its fruit.

柠檬树的出现稍微晚一些，它的扩散过程很难被追溯，但是扩散过程至迟在十二世纪完成。

Generally, there are two stages throughout the reaction of Si〓N〓 and interlayer. At the first stage, the liquid Cu enwraps Nb phase, and Nb diffuses into the Cu. The reaction layer of NbN and Nb〓Si was caused between Nb and Si〓N〓.

第二阶段，Cu全部熔化，Ni向液态金属中扩散溶解，形成Cu-Nb-Ni液态合金，液态合金中的Nb、Ni向Si〓N〓界面扩散并与之反应形成由NbN、Nb〓Si和Ni〓Si组成的反应层。

The applications of outgassing technology in industrial field were summarized with three kinds of outgassing models analyzed,ie.
