水样采自某单位自备水源。试验结果表明，未氯化自来水有机提取物致突变反应阴性，加氯自来水样诱发沙门氏菌致突变率升高；在一定范围内，随氯浓度增加，不会显著增加水样的致突变性。

Because of specificity and high efficiency, the catalytic efficiency of cellulase is high(more 103~1013 times than general catalysts), the condition of catalytic reaction is mild and the catalytic activation can be adjusted and controlled, which can improve remarkably semblance and handle of fabrics during finishing fabrics by biological catalyzing, moreover cellulase can replace some chemical materials such as acid, cocain, chlorine and phosphorus etc, so as to decrease pollution, make no waste-water and protect environment.

由于酶具有专一性和高效性，采用生物催化，其催化效率高比一般催化剂高10~3～10~(13倍，催化反应条件温和，催化活性可调节控制，应用在纺织品处理上，能显著改善织物的外观和手感，并能取代一部分酸、碱、氯、磷化合物等化工原料，从而减少污染，不产生污水，有利于环保和生态。而且酶本身又无毒，容易生物降解，不会引起环境污染，所以酶处理已被公认为是一种符合环保要求的绿色印染加工方法。本文选用了市场上常用的纤维素酶R-10和纤维素酶ECS2610两种生物酶。

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。
