In the first place , with the comparison among several sorts of configurations between the asu and gas turbine , ep - asu is theoretically proved to have better overall igcc power output , overall efficiency and net cost of power generation than lp - asu . furthermore , the pressure ratio of the asu and the temperature diffenrence of the main reboiler / condencer are found to be the two key factors which affect the power consumption by the asu 具体来说，本文首先通过对空分系统与燃气轮机配置方案的深入研究和对比，从理论上说明了ep - asu与lp - asu相比能耗更低、投资更省、效率更高；并进一步得出空分压比和空分系统的主冷温差是影响空分系统能耗的关键性因素。
In the countries represented by the u . s . , the principal - agent relationships between outside shareholders and inside shareholders and management dominate , thus the market mode l governance structure came into being . one key factor to the model ' s forming is the well - developed security market ; " shareholder paramount " is the creed of this model 在以美国的为代表的国家里，外部股东与内部股东、经营者之间的代理关系成为主要矛盾，成就了市场模式的公司治理结构，发达的证券市场是这一模式形成的关键性因素， “股东至上”是这一模式的纲领。

It is an important that bacteria contaminated vaccine in the biologicals production . we collected 703 samples of cell culture , virus cultivation and harvest which were contaminated by bacteria during poliovaccine production within two years . we checked these samples by bacteriological method and antibiotics sensitivity tests were done . it shows that 1 ) the main contaminated bacteria come from staphylococci , bacilli and streptococci of environment in the poliovaccine production . 2 ） it is effect that antibiotics to contaminated bacteria are doxycycline , albiotic , prescription 2 , cefotaxime na salt , gentamycin , neomycin , aureomycin and erythromycin 在疫苗生产实践中，细菌污染是影响疫苗质量和产量的关键性因素，笔者通过了两年左右的时间，选取正常生产中零星细菌污染的细胞培养瓶、病毒培养瓶及收毒污染样品等共703份，进行细菌学检查，并对造成污染的主要细菌种类进行了各种抗菌药物的耐药性实验，结果表明：我所脊灰疫苗生产中主要的污染威胁来自环境中的葡萄球菌，潜在威胁是杆菌和链球菌；强力霉素、林可霉素、配方2 、噻孢霉素钠盐、庆大霉素、新霉素、金霉素和红霉素等抗生素对目前引起污染优势细菌-葡萄球菌有明显的抑菌效果，可作为疫苗生产后备抗菌手段参考
At new stage in the new century , we only depend on strengthening armed forces relying on science and technology , could offer the strong military guarantee for building the well - to - do society in an all - round way , offer military support for reunifying the motherland , advance the overall change of the chinese society 科技作为一种重要的国家安全要素，在国家安全和国防建设中的作用越来越突出，信息知识和高科技将成为克敌制胜的关键性因素。新世纪新阶段，为全面建设小康社会提供强大的军事保障，为祖国统一提供军事支持，为推进中国社会的总体变革，必须依靠科技强军。
