查询词典 yolk membranes

Salsa was a transmembrane protein with four transmembrane domains. Earlier experiments indicated the conserve glutamyl residue in the fourth transmembrane domains might participate in the proton translocating across the membranes.

盐地碱蓬液泡膜H〓-ATPase c亚基第四个跨膜区存在高度保守的谷氨酸残基，先前的研究表明此谷氨酸残基可能与H〓跨脂双层运输有关。

The key innovation of the preparation method of the PDMS composite membranes lies in: The supporting layer is dipped into a kind of polar solvent so that the micropores are soaked and saturated by the solvent; with that the supporting layer is set on a flat surface, then the dilute PDMS solution is spayed spontaneously on the substrate; finally the solvent volatilizes and the PDMS skin layer is formed.

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。
