In this research, large volume stainless pots, high－quality pottery pots and enamel pots, instead of traditional small volume pottery pots, were used in storing several kinds of fresh liquor like "Shuanggou Liquor" etc.and the analysis of stored liquor by gas chromatography and atomic absorption spectrum indicated that the application of large volume stainless containers, instead of the traditional pottery pots, could not only advance liquor aging , produce flavour and remove precipitate, develop soft liquor style, stabilize and improve liquor quality,harmonize the balance of components , decrease liquor loss and liquor storage space,but also promote oxidation , reduction, esterification and molecular hydrogen bond association in the process of liquor storage.

对&双沟酒&等各香型酒，利用大容器的不锈钢罐、优质陶缸和搪瓷罐代替传统小容积陶坛或陶缸贮存新酒作了试验研究。采用气相色谱和原子吸收光谱对贮酒分析，得出采用不锈钢等大容器代替传统小陶罐贮存酒，不但可使酒在贮存过程中进行氧化、还原、酯化和分子氢键缔合作用，促进酒体老熟去杂增香，使酒体柔和老熟、成分平衡协调，稳定和提高酒质；而且还可以降低酒的损耗和减少贮酒库占地面积。孙悟

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。
