查询词典 chlorine dioxide

It is prepared from pentachluorobenzonitrile by using KF as fluoride to substitute chlorine in the presence of benzonitrile under high temperature. But owing to the low solubility of KF and rigor synthesis condition, and the parallel auxiliary reactions, the speed of reaction as well as the yield is very low.

五氟苯甲腈的合成开发以五氯苯甲腈为原料在较高的温度下用氟化钾做氟化剂，通过取代苯环上氯原子而得到的，由于氟化钾在溶剂中溶解度低，合成条件要求苛刻，反应速度较慢，同时存在有平行竞争副反应，因而反应收率较低，国内尚无厂家生产。

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。
