丁化作用

The electric conductivity of solid polyiodides increases largely as the aggrandizement of polyiodide anions"polymerization degree. The solid polyiodides have excellent sterilizing effects and the effect of tetra-n-butyl ammonium undecaiodide is the best of them, and the sterilizing effects increase as the aggrandizement of polyiodide anions" polymerization degree. The sterilizing effects of resinic polyiodides increase as the aggrandizement of polyiodide anions polymerization degree, the heptaiodide resinic polyiodide has better sterilizing effects than the triiodide and pentaiodide.

固体高聚碘系列化合物的电导率随着高聚碘阴离子聚合度的增加而增加，并且增幅较大；固体高聚碘对常见细菌均具有很好的杀灭作用，并且随着高聚碘阴离子聚合度的增加，杀菌能力也随着增强，其中正四丁基十一碘化铵杀菌剂的效果最佳；树脂高聚碘随着高聚碘阴离子聚合度的增加，杀菌能力增强，碘七树脂高聚碘的杀菌效果要明显好于碘三树脂和碘五树脂高聚碘。

TOAB (tetra-n-octyl-ammonium bromide) serves as a catalyst initiating the reaction between dodecanethiol and Cux(x-2). When it is absent, nanoparticles were not formed and white floccules were observed in the bottom of toluene phase .

四丁基溴化铵起到催化剂的作用，在它存在的时候，十二烷基硫醇和铜母体的氧化还原反应优先发生。

Objective:The aim of the experiment is to search for the regulation that the hepatic stem cells abnormally differentiate into cancer cells. In the experiment,the variating regulation of PCNA,c-kit and c-myc in the formation and development of HCC will be interpreted with immunohistochemistry and RT-PCR. So,the initial mechanism that hepatic stem cells abnormally differentiate into cancer cells from the levels of cell,protein and gene will be clarified. The last,the inhibition to HCC with ulinastain will be studied,from which,a new way of clinical prevention and treatment for HCC will expect to be explored.

二、目的本实验旨在探讨以卵圆细胞为代表的肝干细胞在HCC发生、发展过程中在肝组织内分布规律，并通过免疫组化、RT-PCR等技术阐明PCNA、c-kit、c-myc在HCC发生、发展过程中的动态演变规律，从细胞、蛋白、基因三个水平初步研究卵圆细胞向癌细胞异常分化的机制，同时观察乌司他丁对HCC发生、发展的抑制作用，为肝癌的临床预防和治疗探索新的途径。

Objective To study the mechanism of the inbitory effect of matrine on central nervous. Methods In the present study, incubation of postnatal Wistar rat cortex neurons in culture with matrine at 0.5, 1.0, 2.0mmol/L was carried out to have knowledge of the effect of matrine on the expressions of GABAR.

目的 观察苦参碱对鼠原代培养皮质神经元γ-氨基丁酸受体蛋白表达的影响，探讨苦参碱抑制中枢的作用机制方法对Wistar新生大鼠原代培养皮质神经元分别给予剂量 0.5、1.0、2.0mmol/L培养基的苦参碱进行药物干预，4h后用细胞免疫组化方法测定GABAR的蛋白表达。

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。
