These revealed that high dose copper can destroy function of erythrocytic membrane and cause oxidative stress, which may be one of the mechanisms of goat erythrocytic haematolysis induced by high dose copper. 3 High copper caused the increase of osmotic fragility of erythrocyte and AGLT50 in acor glycerine solution.

高铜导致红细胞膜超氧化物歧化酶和谷胱甘肽过氧化物酶活性降低，氧化产物丙二醛含量增多，引起红细胞抗氧化功能降低，诱发氧化胁迫，使得红细胞处于氧化应激状态，这可能是高铜致羊红细胞溶破机制之一。

Chemiluminescent immunoassay is one of the advanced immunoassay ofnon-radioisotopic immunoassay because of its high sensitivity, wide dynamic range,high accuracy, stable labeled protein, full automation and extensive application field.CLIA using acridinium ester derivatives as chemiluminescent label has advantages oflow background, high signal-to-noise ratio, no need of catalyst and simpleluminescence system. Different aspects associating the DMAE·NHS-based CLIA were studied in thisthesis, including synthesis of acridinium ester, chemiluminescentcharacteristics of DMAE·NHS, labelling antibody or streptavidin with DMAE·NHS,two-site sandwich chemiluminescent immunoassay for TSH, two-sitesandwich chemiluminescent immunoassay involved biotin-streptavidinsystem for TSH, and competitive chemiluminescent immunoassay usingbiotin-streptavidin system for TT〓. The desired acridinium ester, DMAE·NHS, was synthesized according to thereference method with some modifications. The products were identified by IR, NMR,MS and elemental analysis. In our method, KOH was used in place of NaOH tosynthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate waspurified on a silica gel column with chloroform/ethylacetate(4:1, v/v) as eluent andfurther purified by triturating with hexane/acetone(2:1, v/v).

DMAE·NHS的合成是本论文的关键和难点，我们对文献方法进行改进：文献方法用氢氧化钠与3，5-二甲基-4-羟基苯甲酸反应制得3，5-二甲基-4-羟基苯甲酸钠，再用3，5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3，5-二甲基-4-羟基苯甲酸苄酯，我们用氢氧化钾代替氢氧化钠，使合成取得成功；在合成2'，6'-二甲基-4'-苯基-吖啶-9-甲酸酯时，文献方法对粗产品进行两次硅胶柱层析纯化，第一次柱层析用氯仿／乙酸乙酯(4∶1，V∶V)作溶剂和淋洗剂，第二次柱层析用己烷／丙酮(2∶1，V∶V)作溶剂和淋洗剂，按照文献方法得到的不是所需要的化合物，我们只进行第一次柱层析纯化，然后用己烷／丙酮(2∶1，V∶V)进行研磨，过滤，洗涤，除去溶于己烷／丙酮(2∶1，V∶V)的部分，得到所需要的产品。

Aerostatic bearings have been widely applied in high-speed and high-precision systems, but the need of high precision machining and low loading capacity retard their development.

中文摘要气静压轴承被广泛应用於高速与高精度系统中，但是高精度加工之需求及低承载能力也阻碍了它的发展。

He explained that after 6 years of efforts, although the city-controlled regulation of the main urban areas has achieved a full coverage, the optional planning and management resolved , but at that time in order to improve the utilization of land, often the community capacity rate approvable has been too high with the floor area ratio generally between 4-6, some are even over 10, resulting in high community population density and high traffic pressure.

扈万泰解释，经6年多努力，我市虽然对主城区控规实现了全覆盖，解决了规划管理随意性大的问题，但当时为了提高土地集约利用率，往往在小区建设的容积率审批时一直过高，普通小区的容积率一般在4—6之间，有的甚至超过10，导致一个小区人口密度过高，公共活动空间少，交通压力大。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
