The influences of the inclusion of Na~+ into each conformer (C7AB, C7"AB, C7eqB, C5A, C7axB orα"B) of AD molecule on the Ramachandran angles of molecular backbone and the hydrogen bonds in AD moiety were discussed in detail. It was found that in the forming process of bidentate structures of Na~+-AD ion-complexes, the original H-bonds in AD molecule were fully broken down, accompanying with the new formation of the two Na-O bonds.

论文中详细探讨了Na~+-AD络合离子六种构象的空间构型，分析了丙氨酸二肽与Na~+作用过程中AD分子骨架Ramachandran角及分子内N(1)–H(1)…O(2)、N(2)–H(2)…O(1)、N(1)–H(1)…N(2)和N(2)–H(2)…N(1)氢键的变化，研究发现Na~+与AD分子形成双齿结构时，AD骨架中原先的氢键全部被破坏，继而形成了两个新的Na-O键；Na~+与AD分子形成单齿络合离子时，AD骨架中原先的氢键或者得到增强或者断裂之后出现新的强度更大的氢键。

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。
