在这篇论文中,采用动电位扫描和交流阻抗法评价了锅炉主体系统溶液中水溶性咪唑啉缓蚀剂的缓蚀性能,并解释了缓蚀机理.实验得出影响咪唑啉缓蚀剂缓蚀性能的因素主要有温度,浓度,预膜时间,并针对这三个因素的不同影响设计了多组模拟体系,验证出该缓蚀剂是一种阳极型的缓蚀剂,缓蚀性能主要来自于吸附成膜后形成空间位阻,从而隔离了碳钢基体和腐蚀介质.依据实验数据计算得到其吸附能,从吸附能的大小可以判断出吸附过程包含物理吸附和化学吸附两种.实验还表明预膜可以很好地阻碍腐蚀的过程,预膜后的碳钢在含有很少量缓蚀剂的体系中就能较好地防止腐蚀,这样就减少了缓蚀剂的用量,节约了资源.虽然预膜时间对自腐蚀电位的影响不大,但通过降低腐蚀电流密度和增大极化电阻的方式也起到了防腐功效.
Among the thesis,is it work up electric potential scan and exchange impedance law not to think boiler subject systematic solution water soluble miaow thiazole quinoline lose to lose performance slowly pharmaceutical slowly to adopt,and has explained the mechanism of losing slowly.It influences the miaow thiazole quinoline to lose slowly that the experiment is drawn the pharmaceutical loses slowly the factor of performance has temperature mainly,density,the membrane time in advance,and design many group's simulation systems for different influence of these three factors,is it is it should lose pharmaceutical to lose pharmaceutical slowly one positive pole type ,lose performance is it is it form space location hinder after the membrane to absorb to come from mainly slowly slowly to appear to prove,thus isolated the carbon steel base body and corrode the medium.Calculate according to the experimental data that can absorb by it,can judge the course of absorbing and include physical absorption and chemistry and absorb two kinds from the size that can absorb.Experiment indicate membrane can hinder course that corrode well in advance ,carbon in contain steel few quantity lose behind the membrane in advance also,reduce the consumption of the pharmaceutical of losing slowly like this,economize resources.Though membrane time arises to the antiseptic efficiency by way of reducing and corroding the density of the electric current and increasing the resistance of polarising to corroding the influence of the electric potential by oneself not big in advance.
在药物毒性的体外实验中,需要检测化学药物对细胞的增殖及存活的影响,不同于动物实验可以直接观察动物的生理现象,体外实验需要检测细胞存活率,而利用细胞某生命活动过程中产生的物质来检测细胞是否存活及存活量.本实验利用MTA法比色测定,用于测定H2O2对Hela细胞的毒性.
Need to examine the chemistry influence of medicine propagate cell and survival in the experiment outside the body of the medicine toxicity,differing from the animal experiment can observe the physiology phenomenon of animal directly,the body tests to need to examine a cell livability outside,but makes use of the output material in the cell some life movable process to examine cell whether survive and survive quantity.This experiment makes use of a MTA method ratio color measurement,useding for measuresing H2 O2's toxicity to Hela cell.
