Kosmotropes are stabilizing solutes which increase the order of water (such as polyhydric alcohols [ 307 ], trehalose, trimethylamine N -oxide, glycine betaine, ectoine, proline and various other zwitterions) whereas chaotropes create weaker hydrogen bonding, decreasing the order of water, increasing its surface tension and destabilizing macromolecular structures (such as guanidinium chloride and urea at high concentrations).

这是稳定增长kosmotropes溶质水秩序(如多元醇〔307〕、海藻糖、甲胺氮氧化物、甜菜碱、ectoine，脯氨酸和其他各种盐)而创造chaotropes氢键较弱，为了减少用水，增加其表面张力和大分子结构不稳定。

Methods 4-Hydroxy- benzonitrile was treated with sodium hydrogen sulfide and anhydrous magnesium chloride in dimethyl formamide to give thioamide, which was then directly cyclized with ethyl 2-chloroacetoacetate without separation to give ethyl 2-(4-hydroxyphenyl)-4-methylthiazole-5-carboxylate(2) in one-pot; then 2 was formylated with Duff reaction adopting hexamethylenetetramine in trifluoroacetic acid to give ethyl 2-(3-formyl-4-hydroxyphenyl)-4-methylthiazole-5-carboxylate(3); finally, the target compound was obtained by the treatment of 3 with hydroxylamine hydrochloride and sodium formate in formic acid.

采用&一勺烩&方法，以4-羟基苯甲腈为起始原料，首先与硫氢化钠和无水氯化镁在N，N-二甲基甲酰胺中反应，所得中间体不经分离，直接加入2-氯乙酰乙酸乙酯进行环合反应，得到2-(4-羟基)苯基-4-甲基-5-噻唑甲酸乙酯（2）；然后通过六亚甲基四胺/三氟乙酸进行Duff反应，得到2-(3-甲酰基-4-羟基)苯基-4-甲基-5-噻唑甲酸乙酯（3）；再经盐酸羟胺/甲酸/甲酸钠体系脱水得到目标化合物。

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。
