相较起来，不同处在於多对一变换只能呼叫上述副函式'''一次'''，且副函式的回传值必须'''就是'''整个变换程式回传的值。

Wheares under buffer pH5.2, there is no strong static electricity and instead being a longer wavelength movement; SDS\'s participation just restricts the relative movement of heme\'s ethylene; a new fluorescent peak forms and the reduction of enzymatic activity is due to the packing of micella\'s formation.

强变性的阴离子表活剂SDS与带净正电荷和弱负电荷的SBP(处于pH2.6和4.2缓冲液中)有强烈的静电力作用，酶活力丧失，二级结构变化，荧光强度增加，特征Soret发生蓝移，卟啉环的π-π*共轭的分裂能增大；而当SBP带净负电荷(pH5.2)时，没有静电吸引力，Soret带发生红移；SDS的引入只是限制了血红素上乙烯取代基的运动，使其与卟啉环共轭：极性环境的变化导致产生新的荧光峰；酶活力因胶团包裹作用而有下降。

The reduction of PO4-P turnover time in the microcosms containing fish was attributed mainly to the acceleration of PO4-P regeneration by fish.

这些鱼类使微型生态系统中PO4-P的周转时间缩短，可能主要是它们加速了系统中PO4-P再生的结果。

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。
