Since 1980, many new species records have been reported from Beijing, Anhui Province, Sichuan Province, and Yunnan Province. They include species belonging to the chytridiomycetes, oomycetes and ascomycetes and their anamorphs from freshwater environments.

自从20世纪80年代初期该研究在我国大陆开展以来，许多淡水生卵菌、壶菌、子囊菌和半知菌类等的新种和新记录相继被报道于北京、安徽、四川和云南等地。

Karstification is the main forming mechanism of the carbonate karst reservoir near the unconformity, and the depth influenced by atmogenic freshwater is about 150 m under the Caledonian unconformity.

岩溶作用是潜山不整合面附近碳酸盐岩岩溶储层的主要形成机理，主要集中在加里东不整合面之下150m的深度范围。

The marine carbonate near the unconformity was mainly reconstructed by strong atmogenic freshwater during the Indo-China and Yanshan Movement, being better reservoir. The reconstructed records behave as following: the ratio for 87Sr/86Sr in the different carbonate minerals or structural components is higher than carbonate matrix, while the δ13C and δ18O value in mass of samples in the different carbonate minerals or structural components are lower than carbonate matrix.

在不整合面附近的海相碳酸盐岩主要受到印支、燕山再曝露期古喀斯特作用强烈的大气淡水的改造而形成良好的岩溶储层，这种改造作用的记录表现在各种洞或脉中的碳酸盐矿物的87Sr/86Sr比值显著高于基质碳酸盐，而大多数样品的δ13C和δ18O值则显著低于基质。

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。
