Our study showed that povidone-iodine solution as well as sodium hypochlorite solution with the concentration greater than 0.125% was bactericidal. The use of these two antiseptics in the treatment of dermatophytosis complex seems to be promising.

我们研究发现普维酮－碘溶液和次氯酸钠溶液在浓度0.125%以上有杀菌效果，使用它们治疗复杂性足癣霉菌病似乎是大有可为的。

Therefore we added three candidate antiseptics-sodium hypochlorite solution, propolis, and povidone-iodine solution-to the treatment strategies and compared in vitro the antibiotic activities against Pseudomonas aeruginosa. We intended to know whether the antiseptics used in the past were effective and meanwhile exploring new potential antiseptics for the treatment of dermatophytosis complex.

为了解这些过去使用的杀菌剂是否有效，并同时探索有效的新杀菌剂来治疗复杂性足癣霉菌病，我们又加入了三种杀菌剂－次氯酸钠溶液、蜂胶，和普维酮－碘(povidone-iodine)溶液－来比较它们对绿脓杆菌的体外抗菌活性。

Objective To prepare iodine microspheres with blank cross-linked dextrin microspheres, which could be used as dressing for chronic wounds with exudation.

目的 用空白交联糊精微球作为载体制备交联糊精－碘微球，作为敷料用于慢性有渗出物伤口的治疗。

The influence of each condition on the reaction speed and yield was studied, and the optimal conditions were: the ratio of the amount of substance of aromatic amine and heptafluoro-isopropyl iodine was 1:1.1~1.5, the amount of substance of sodium dithionite, sodium bicarbonate, aniline compounds were respectively 1.1~1.3, the amount of substance of phase transfer catalyst TBAB and aniline compounds was 0.05~0.1, the concentration of aniline compound was 0.5~1.0 mol/L, reaction temperature was 10~20 ℃, and the solvent was aether.

最佳结果为：芳胺与七氟异丙基碘的物质的量比1：1.1~1.5，连二亚硫酸钠、碳酸氢钠与苯胺的物质的量分别为1.1~1.3，相转移催化剂四丁基溴化铵与苯胺的物质的量比在0.05~0.1，溶剂总用量使苯胺浓度在0.5~1.0 mol/L；反应温度10~20℃；溶剂采用乙醚。取代基供电子性越强，反应时间越短，产率越高；氨基的对位优先反应，氨基的邻位较难发生反应；且七氟异丙基总是优先取代在芳环电子云密度较高的位置上。

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
