Continuous - flow column studies were performed to evaluated fluoride removal characteristics , regeneration procedures and extent of deterioration of the adsorbents 研究了吸附等温线的形式和饱和吸附容量,明确了连续处理的控制条件、再生水平和时间。
Schottly barrier diode can be used as rectifying and continuous - flow unit in high frequency rectifying , switching and holding circuit , yet reducing the power consumption and circuit noise , enhancing the circuit efficiency and operation frequency 肖特基二极管在高频整流、开关电路和保护电路中作为整流和续流元件,可以大幅度降低功耗,提高电路效率和使用频率,减少电路噪声。
However there are no numerical computations about continuous - flow pcr chip . so the microfliudic velosity and temperature distribution in direct microchannel , curve microchannel and widing microchannel with 100 m width and 50 m depth are computated using fluent software Pcr微流控芯片的制备则是采用本文提出的新方法,在pmma材料上制备出横截面为矩形、底面光滑、逶迤型的微通道。
And the level of routine activity of the tested fish in large - scale closed respirometer in this study was higher than those of the either , which was restricted by the smaller room of respiratory chamber in the continuous - flow respirometer used in the two reported studies . O )本实验采用的是大型封闭式呼吸室,对实验鱼的日常活动的限制作用较小,而其它两种鱼采用的是小型流水式呼吸室,限制了鱼体在测定过程中的活动性。
The development history , the present status and the future trend of biochip is systemly summarized firstly in this paper , then the important status in the history of biochip and the research significance of continuous - flow pcr chip are pointed out 本文对生物芯片以及pcr技术的发展历史、研究现状以及未来发展趋势进行系统回顾和分析。作为第二代生物芯片的pcr微流控芯片,因其在分子生物学和生物医学上有着重要的应用,是一种值得研究的重要芯片。
Then based on the principle for pcr , 20 - cycle continuous - flow pcr is designed using cad software . to the designed 20 - cycle continuous - flow pcr chip , a krf excimer laser ( direct write method ) is adopted as the fabrication technology , and the polymethyl methacrylate ( pmma ) is selected as the substrate . so the appearances of pmma surface etched before and after by 248nm excimer laser under different incident fluences are analyzed using sem 为此在应用扫描电镜和三维形貌分析仪对pmma表面被准分子激光刻蚀前后的形貌、刻蚀粗糙度以及单脉冲刻蚀率等进行详细分析的基础之上,总结出了准分子激光刻蚀pmma的宏观规律和微观刻蚀机制,提出了一种准分子激光刻蚀pmma的是光热光化学以及羽辉共同作用的理论解释。
