Here, we examine the phylogenetic relationships of the Clemmys complex of the freshwater turtles using 985bp of the DNA encoding the mitochondrial genes ND4 and adjacent tRNAs gene. These data contain 235 parsimony informative characters that we use to erect hypotheses of relationships for the Geoemydidae and Emydinae turtles.

本文测定了四眼斑水龟和黄喉拟水龟线粒体基因组的ND4基因，用部分ND4基因及相邻tRNA基因共985bp的序列(包含简约信息位点235bp)讨论了它们的系统进化关系。

The current taxonomic status of the Clemmys complex of freshwater turtles places the Old World genera Mauremys and Sacalia in the Geoemydidae and the New World genus Clemmys in the Emydinae. These three genera were previously considered to be congeneric.

水龟组由旧大陆潮龟科的拟水龟属、眼斑龟属和新大陆龟科的水龟属组成，这三个属以前一直被认为是同属的，但没有得到形态学和染色体等方面的认同。

It used to happen naturally with the Nile's seasonal floods; after the completion of Egypt's High Dam in 1970 (one of the most ambitious engineering projects on earth), these seasonal floods came to an end, but a vast network of irrigation canals continued to bring gallons of freshwater to the people who worked the land, the fellahin , ensuring salinity levels remained low.

过去，这一使命自然而然地要由尼罗河的季节性洪水来完成。但是，1970年后，埃及大水坝的竣工（世界上最宏伟的工程项目之一）为这种季节性洪水划上了句号。但是，巨大的灌溉网络继续将大量的淡水送到在田间工作的人--农民的身边，从而使土壤盐度仍然维持在低水平上。

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。
