General layout: General idea should focus on protecting urban water sources, restoring riverways, wetlands and groundwater, improving the water body function, strengthening water resources allocation and water function regions management. Based on existing water project structures, the generallayout follows as that urban water sources conservation on the upriver, wetland and groundwater restoration on mid-river and coastal wetland and estuarine eco-area restoration on the downriver, achieve the target that rivers and lakes 'connection, green bank, clean water, flowing river', then form aquaticecosystem protection and guarantee system.

以保护城市水源地为重点，以修复河道湿地、地下水和改善水体功能为核心，以强化水资源配置和水功能区管理为关键，基于现有的水利工程体系，在流域上游建立以城市饮用水水源地为主体的生态保护屏障，在流域中游建设以湖泊为点、河道为线、地下水为面的水生态修复系统，在流域下游构建以滨海湿地和入海河口为中心的生态恢复区，遏制水土流失，增强水源涵养，保护水功能区，实现河、湖&连通、绿岸、清水、流水&，进而形成防控结合的水生态环境保护与修复保障体系。

Results of the study demonstrate that arsenic in the surface soil of Chengdu basin has approximately six kinds of sources, among which sedimentary series of post-Triassic, Jurassic and Cretaceous systems along Longmen orogenic belt and acid magmatic and basic-ultrabasic rocks in the area are three main sources.

The solubility of Cu from Cu oxide, Cu sulfate, tri-basic copper chloride, Cu lysine, and Cu proteinate was determined in deionized water, dilute acid or buffer. Twenty crossbred (Poll Dorset X Small Tail Han-yang) wethers were used to assess the effects of copper sources on concentration of plasma copper in sheep. All sources provided 8 mg of added Cu/kg of DM.

研究主要分三部分进行：(1)选用硫酸铜、氧化铜、碱式氯化铜、赖氨酸铜和铜蛋白盐五种铜源，利用不同溶剂模拟绵羊消化道的不同环境，对各种铜源的溶解性进行分析，并用20只杂交一代羯羊作为试验动物，采用单向分类设计，探讨各种铜源对绵羊血铜代谢规律的影响，各种铜源的铜添加水平均为8mg·kg~(-1)。

Studies of Sr, Nd and Pb isotopes of various stratigraphic units, granite plutons and fluorite ores indicate that the metallogenic materials of fluorite were derived from multiple sources, and the isotopic composition of fluorite is characterized by crust_mantle mixed sources.

各地层单元、花岗岩体和萤石矿石的Sr、Nd、Pb同位素研究表明，萤石的放射性同位素组成具有壳、幔源混合的特点，成矿物质来源具有多源性。

Firstly, a mathematic model was constructed to deal with fault isolation. This model mainly considered the associations among fault sources and available testing of hierarchical system, the affiliation of faults with replaceable units in different levels, the prior probability of fault sources and the available testing costs. Secondly, a quasi multi-step look-ahead search algorithm was presented which employed the information gain as its heuristics. This algorithm could realize optimization of testing sequence in different isolation levels.

首先基于层次系统故障与测试之间的关联关系，以及故障与不同层级可更换单元的隶属关系，结合故障的先验概率与可用测试成本，构造了层次系统故障隔离问题的数学描述模型；然后以信息增益为启发策略，提出了一种准多步前向搜索算法，实现了不同隔离级的测试顺序优化。
