Aim To investigate the production and removal of cyclobutane pyrimidine diners after UVB irradiation and the effect of baikal skullcap root, szechwan lovge rhizome and epigallocatechingallate on the irradiation damage in HaCaT cells, and finally, to clarify the probable regulatory mechanisms. Methods HaCaT cells were cultured in RMPI-1640 medium with 10% fetal bovine serum. The time and dosage of UVB irradiation were conducted according to the experimental design. Tested medicines were added into the medium before or after UVB irradiation.

目的 观察中波紫外线辐射后HaCaT细胞光产物胸腺嘧啶二聚体(cyclobutanepyrimidine dimers， CPDs)的生成和清除情况及3种中药活性成分：黄芩(baikal skullcap root， BSR)、川芎(szechwan lovge rhizome， SLR)和表没食子儿茶素没食子酸酯[-epigallocatechin-3-gallate， EGCG]对该过程的干预情况并探讨上述药物对相关调控分子的作用机制。

It acts by selectively binding to dimeric tubulin, inhibiting the formation of the microtubule spindle to block cell division.

它通过选择性的结合二聚体微管蛋白抑制微管纺锤体的形成阻滞细胞分裂。

And in the process of research for temperature effect on π-A isotherm, it's proved that temperature has a little effect on the insoluble films of synthesized dimeric surfactants. But it has a great effect to the monomer of the surfactants.

另外，在研究温度对它的曲线影响时发现，温度对合成的二聚表面活性剂成膜的影响很小，而这种结构的单体受温度的影响非常明显。

By co-immunoprecipitation, a complex of tau with Hsc70 and dimeric CHIP was observed.

免疫共沉淀发现tau蛋白、Hsc70和CHIP二聚体共存。

Mass spectrometry provided evidence for the dimeric serotonin species from UV radiation studies.

以质谱分析照射 UV 后变色的 serotonin 标准品，可侦测到 serotonin 形成二聚体的结构。

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。
