The analysis of 1H NMR showed that the succinyl group was successfully conjugated to the amino group of chitosan molecule, and the degree of substitution of Suc-Chi values increased with increasing succinic anhydride/amino mole ratio or reducing the molecular weight of chitosan.

利用壳聚糖和琥珀酰酐反应合成了N-琥珀酰壳聚糖，1H NMR分析表明通过反应可在壳聚糖的侧氨基引入亲水性的羧基，增加琥珀酰酐／氨基的摩尔投料比或者选择分子质量较小的壳聚糖，有利于提高N-琥珀酰壳聚糖的琥珀酰化度。

A series of cholesterol-bearing O-carboxylmethyl chitosan conjugates with different degrees of substitution of the cholesterol moieties and cholesterol-bearing chitosan were synthesized by the succinyl linkages and characterized by Fourier transform infrared, Proton Nuclear Magnetic Resonance (~1H NMR) and elemental analysis. These hydrophobized chitosan derivatives were amphiphilic in nature and their self-aggregation behavior in aqueous media was evaluated by the fluorescence probe technique.

根据0/1水印序列和同义词替换评价模型，将水印有选择地嵌入到原始文本中。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

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。
