Results show that hydroxyl group existing in benzene ring, sulfanilamide being adjacent to hydroxyl group and benzene ring itself are main active sites of this kind of compounds probably. Orbit energy distributing on groups and the number of net charge of N atom determine compounds' insecticidal activity directly.

计算结果表明，该类化合物中苯环上的羟基、羟基相邻的磺胺基团以及与该苯环的组合很可能是该类化合物的主要活性部位，分布在基团上的前线轨道以及N原子的净电荷的多少直接决定化合物的杀虫活性。

Originally inferior test result indicates result , the staphylococcus poisons rates to different oxazole of sulfanilamide being able to bear being 100%, the penicillin poisons rates with the illotycin being able to bear approaching 100% equally , the streptococcus poisons rates most highly , is 61.11% to the penicillin being able to bear, being able to bear to streptomycin , illotycin , Achromycin etc.

结果 本次试验结果表明，葡萄球菌对磺胺异恶唑的耐药率为100%，青霉素和红霉素的耐药率均接近100%，链球菌对青霉素的耐药率最高，为61.11%，对链霉素、红霉素、四环素等的耐药率均超过50%，成为临床治疗的潜在危险，提示安全应用治疗药物的重要性。

In the experiment, first the synthesis process of Sulfaquinoxaline is modified. Then, aimed at three single factors of temperature, rate of aeration and time, a series of experiments have been carried out Through the experiments, the values of the factors are optimized respectively and the feasible oxidation is obtained, which solve the problems of high cost, difficulty and low rate of retrieval.

研究工作对磺胺喹噁啉的合成工艺进行了改进，针对反应温度、反应时间、通气速度三个单因素，进行了一系列的单因素实验，优化出各个因素的最佳值，提出了稳定的氧化条件，解决了工艺中的高成本、高难度、收率低的问题。

Finally,the optimal experimental options could be used to detect the residual sulfonamide in the milk,and get good recovery and reproducibility , therefore ,getting up a quick and simple methode for Solid-pahse extraction technique.

最后将最佳的实验条件应用到侦测牛奶中磺胺剂的浓缩萃取，皆能得到高的回收率与再线性，因此建立一个快速、简单易操作的固相萃取技术。

In this prospective, randomized, controlled, unblinded study, we compared colonization rates of a standard, unimpregnated central venous catheter with rates for silver-coated and chlorhexidine-silversulfadiazine-impregnated CVC.

在这个非盲的、随机对照的前瞻性研究中，我们比较了标准的无预充剂的中心静脉导管和银涂层及预充洗必太磺胺嘧啶银两种中心静脉导管的菌落率。

Methods According to the drinking water legislation in Europe threshold: 0.10mg/L NO2(superscript -, a rapid spot test method for nitrite in water was established by using an optimized composition of reagent mixture and a binary positive/negative response, conducted as follows: a tablet of a mixture of solid reagents containing sulfanilamide, N-(1-naphthyl) ethylene diamine dihydrochloride and sodium chloride was put on a spot test plate of Teflon mould, then, a drop of 30% HCl and a drop of water sample were added on the reagent material.

根据欧洲饮水法规亚硝酸盐限值(0.10mg/L)，使用一种优化的试剂混合物和二元的阳性－阴性反应，建立一种水中亚硝酸盐快速点滴检验法。结果将1片含磺胺、N-（1-萘）乙二胺二盐酸盐和氯化钠的固体试剂混合物放在聚四氟乙烯模的点滴检验板上。加1滴30%盐酸和1滴水样于试剂片上。

Material and method 1.1 tests data 10% get together dimension ketone iodic ointment (Guangzhou Bai Yunshan external use pharmaceutical factory), solution of 0.5% iodic bend over (luxuriant name disinfects pharmaceutical factory), silver of 10% sulphanilamide pyrimidine is mixed hang fluid (make up by oneself [7]), new Zealand hare . 1.2 pollution achieve a face to build model and experiment of bacterium of different remedy curb to regard the place that cause an injury as back of 36 New Zealand hare.

概要： 为适应战场成批烧伤救治的需要，在现有探究的基础上[1-6]，作者进行了三种烧伤外用药对烧伤创面处理的效果探究，以期获得对创面保护功能好、抗菌效果可靠的用药和处理方法。1材料和方法1.1实验材料10%聚维酮碘软膏，0.5%碘伏溶液，10%磺胺嘧啶银混悬液(自行配制[7])，新西兰兔。1.2污染创面造模和不同药物抑菌试验将36只新西兰兔背部作为致伤部位。

Churchill was saved by Lord Moran, using sulphonamides, since he had no experience with penicillin, when Churchill fell ill in Carthage in Tunisia in 1943. The Daily Telegraph and the Morning Post on 21 December 1943 wrote that he had been saved by penicillin.

丘吉尔是被莫兰勋爵用磺胺类药救下来的，因为在1943年，当丘吉尔在突尼斯的迦太基受伤时，莫兰还不知道青霉素呢。1943年12月21号的《每日电讯报》和《晨报》都说丘吉尔是被用青霉素救的。
