Coreius heterodon is an important commercial fish species in the upper and middle reaches of Yangtze River, and one of the appropriate fishes for the study of possible ecological effects of the Three Gorges Dam.

铜鱼作为长江中、上游的重要经济鱼类是研究三峡大坝阻隔效应的重要材料之一。

Random amplified polymorphic DNA technique was employed to detect the DNA polymorphism in 20 individuals of Coreius heterodon in the lower reach of the Yangtze River. 19 arbitrary primers were used and 90 repeatable RAPD bands were generated.

用随机扩增多态DNA技术对长江下游铜鱼20个个体的遗传多样性进行了检测，从40个随机引物中筛选出19个对每个铜鱼的DNA进行扩增。

Comparing the genetic diversity of Coreius heterodon with that of other fishes, the experiment revealed that the genetic diversity of Coreius heterodon in the lower reach of the Yangtze River was a little lower.

通过与其他鱼类的遗传多样性的研究结果比较可初步判断，长江下游铜鱼群体的遗传多样性较低。

Random amplified polymorphic DNAtechnique was employed to detect the DNA polymorphism in 20 individuals of Coreius heterodon in the lower reach of the Yangtze River. 19 arbitrary primers were used and 90 repeatable RAPD bands were generated.

用随机扩增多态DNA技术对长江下游铜鱼20个个体的遗传多样性进行了检测，从4O个随机引物中筛选出19个对每个铜鱼的DNA进行扩增。

It is proved that the conclusion is credible in theory by contrasting the experiment results from the hydrometric stations of Shashi and Linli.

最后通过与长江委水文局在沙市及监利两水文站试验结果对比，证明本文理论上的分析是可信的。

Vallisneria spinulosa maintained high levels of genetic variation both at the species and at the population level. Partitioning of genetic diversity revealed a surprisingly low population differentiation as compared to other hydrophilous angiosperms.

利用等位酶和开发的微卫星标记研究了刺苦草在长江中下流域的遗传多样性和遗传结构，研究结果表明，刺苦草在居群水平和种水平都具有高的遗传多样性；居群间遗传分化程度非常小；居群间历史上存在长距离基因流。

Methods: The following five sites in the city were selected as monitoring spots, namely, the First Smelter of Tongling Nonferrous Metal Group, the second Smelter of Tongling Nonferrous Metal Group, the Changjiang High-speed Passageway, Fenghuangshan Copper Mine district, residential area, respectively. The moss species Hypnum plumaeform e collected from Huangshan mountain was placed in nylon bag of 15.5 cm×5.5 cm in size and 2.0 mm×2.0 mm in meshes, with each bag having 3 g moss and then sealed by a nylon wire. Moss bags were suspended in five urban exposure sites and then gathered after two months. The content of heavy metal in the tested moss were analysed by atomic absorption spectroscopy.

选取铜陵市的铜陵一冶、铜陵二冶、长江快速通道、凤凰山铜矿区和居民区5处监测点，以采自黄山的大灰藓为材料，用尼龙筛网（网眼2.0 mm×2.0 mm）做成15.5 cm×5.5 cm的矩形袋子，每袋放3 g，2007年3月22日悬挂于各监测点，完全暴露在空气中，2个月后取回，采用原子吸收光谱法对样品中Cu、Cd、Cr、Pb、Zn 等重金属元素含量进行测定。

Ichthyolatry in tribes near water is a common phenomenon. Fish Gods remains are easily found in the Yangtze River Basin, Yellow River Basin, and Weihe Basin.

鱼崇拜是傍水而居的部落－部族民中的一个普遍现象，长江流域、黄河流域、渭河流域都可以找到其遗存。

M and RCC concrete below the elevation and with an upstream conventional concrete slab structure for impermeabilization,the authors develop an inhomogeneous multi laminate media element model for seepage analysis of RCC dams based on the research of the numerical procedure of nodal virtual flux and the technique of draining substructure for drainage holes.

基于长江三峡大坝碾压混凝土方案左厂房 12号坝段上部为常态混凝土、下部为上下游面均设有常态混凝土的防渗结构型式的碾压混凝土坝的特点，借助于渗流场求解的结点虚流量法及排水子结构技术，并提出&排水孔开关器&的概念和渗流非均质成层材料单元模型，对坝中设计时存在的主要渗流疑虑问题、大坝的防渗与排水设施渗控方案的特性进行了数值分析研究。

Wuhan lies in the east of Jianghan Plain and is the interjunction of Yangtze River and Han River.
