It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

Objective: To study the expression of CD44v6 protein in the dysplasia, carcinoma in situ, invasive squamocellular carcinoma and adenocarcinoma of cervix uteri, and the relationship between the expression and the prognosis.

目的：了解CD44v6在宫颈上皮不典型增生、宫颈原位癌、宫颈浸润鳞癌及腺癌中的表达及其与预后因素的关系。

A micro-monolithic column was prepared by in-situ free radical polymerization of stearyl methacrylate with ethylene glycol dimethacrylate in the presence of the initiator AIBN and a mixture of porogens including iso-amyl alcohol and 1,4-butanediol.

以甲基丙烯酸碳酰十八酯为单体，乙叉二甲基丙烯酸酯为交联剂，异戊醇和1，4-丁二醇为二元致孔剂，偶氮二异丁腈为引发剂，原位制备了具有强疏水性的SMA整体微柱，并利用此整体微柱在普通高效液相色谱仪上测定滴眼液中氧氟沙星的含量。

Ii The Ti/C ratio had better be in accord with the stoichiometrical relation of TiC.

该图的建立，对于在实际生产中选择合理的反应工艺参数以及预测和控制原位TiCp/Fe复合材料的组织均有指导意义。

Digitatum were released from the hyphalapex, occasionally releasing from the subapical or original sites.

原生质体释放有顶端、侧端和原位释放3种方式。

Purpose: To compare the regeneration of corneal subbasal nerve fiber bundles after laser in situ kerotomileusis and both-sides LASIK, and to provide objective proof for rationalized clinical operation.

目的：利用共聚焦显微镜观察比较准分子激光原位角膜磨镶术(Laser in situ keratomileusis，LASIK)与准分子激光双面角膜磨镶术(Both-sides LASIK ，BSL)术后角膜上皮下神经纤维的再生情况，为临床合理化手术提供客观依据。

Objective Confocal microscopy was used to compare the regeneration of corneal subbasal nerve fiber bundles after laser in situ kerotomileusis and both-sided LASIK.

目的 利用共焦显微镜观察比较准分子激光原位角膜磨镶术(laser in situ keratomileusis， LASIK)与准分子激光双面角膜磨镶术(both-sides LASIK， BSL)后角膜上皮下神经纤维的再生情况。

Purpose: To compare the effectiveness and safety between laser subepithelial keratomileusis and conventional laser in-situ keratomileusis for high myopia.

目的：对比观察准分子激光上皮瓣下角膜磨削术与准分子激光原位角膜磨削术治疗高度近视的临床疗效。

Objective To compare the forward shift of posterior corneal surface after laser in situ keratomileusis and laser subepithelial keratomileusis in high myopia.

目的探讨高度近视准分子激光原位角膜磨镶术及准分子激光上皮瓣下角膜磨镶术术后角膜后表面高度的差异及意义。

Objective To compare changes in higher-order aberration of moderate to high myopic eyes after laser in situ keratomileusis and laser-assisted subepithelial keratectomy.

目的 比较准分子激光原位角膜磨镶术和准分子激光上皮下磨镶术对中高度近视眼高阶像差的影响。

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.

交际能力和语法的关系应该是目标与途径的关系。
