Both of the thermophiles were motile by means of lophotrichous flagella and had high growth rate on medium containing cellulose. Optimal growth occured at 60℃ for the two thermophiles and at PH 7. 5 for Y, PH 7. 37. 5 for W strain. Y strain produced yellow pigment in cellulose medium and had yellow-colored, round or watery colonies in cellulose agar. The colonies of W strain were white -colored and similar in form to that of Y strain. The mesophile, Clostridium sp. B, was motile with peritrichous flagella. The colonies grown on cellulose agar were white and round with slightly undulate margins. The optimal growth temperature and PH of B strain were 40℃ and 7. 0-7. 2, respectively. All of the three Clostridia fermented varieties of carbohydrates and in cellulose media produced the similar end-products: CO〓H〓, ethanol and acetic acid. The DNA compositions were 34 mol% for Y and B, 35 mol% for W strain.

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。
