Three kinds of hydrophytes, Veliveria zizanioides Nash, Eichhornia crassipes, and Oenanthe javanica DC. were used to investigate enrichment ability of nitrogen and phosphor at the different TN levels with TP constant. It revealed the absorption ability of aquatic plants and purification ability of aquatic macrophytes-rhizosphere microorganisms system respectively in aquatic macrophytes-microorganism system for water purification.

研究了不同TN浓度下香根草、水葫芦、水芹等水生植物－微生物系统富集N、P的能力，揭示了水生植物－微生物系统中水生植物的吸收作用和根际微生物系统对净化水质的作用，对水生植物根际微生物系统相应微生物的数量做了定量的统计。

In this study, isobaric tags for relative and absolute quantification labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) was employed to compare the differential protein expressions in MCF7 cells upon 17β-oestradiol (E2) stimulation or serum deprivation versus in normal conditions. A total of 576 proteins with the confidential level of ≥95% were identified, 26 proteins among the 576 proteins were found to be differentially expressed after E2 stimulation or serum deprivation, and among them 10 proteins were up-regulated and 16 proteins were down-regulated by more than two folds.

利用四重用于相对和绝对定量的等量异位标签(isobaric tags for relative and absolute quantification， iTRAQ)标记结合二维液相色谱-串联质谱(two-dimensional liquid chromatography-tandem mass spectrometry， 2D-LC-MS/MS)对雌二醇(17β-oestradiol， E2)和血清各自以及共同作用对MCF7乳腺癌细胞内蛋白质表达的影响进行了比较，共鉴定到置信度在95%以上的蛋白质576种，其中各组相对于正常培养组的细胞共找到26种差异在1倍以上的蛋白质，其中10种上调，16种下调。

In the recent 30 years of the Guhai water-lifting project ,shortage middle arid zone society and the economic development it has made great contribution to since the outly was shortage for a long time,the project facility cannot obtain the immediate service,aging day by day.

固海扬水工程近30a来，为宁夏中部干旱带的社会及经济发展作出了巨大贡献，但是由于长期以来经费短缺，工程设施得不到及时维修，老化日益加剧，为了对宁夏固海扬水工程设施老化状况作出定量的科学评价，通过长期实践并结合数学理论知识，建立了固海扬水渠道工程老化现状评价的数学模型，为固海扬水工程进一步改造和规划提供科学决策的依据。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
