The catalyst prepared by mixed support (MgO+ kieselguhr) had the decrease in selectivity to CHN for support's acidity, but the change is very little.

采用混合载体浸渍的催化剂，由于硅藻土的酸性作用，环己酮的选择性略有降低，但对催化剂的整体活性影响不大。

It was found that Pd-Co/active carbon catalyst was the optimal catalyst, and Pd-Co/γ-Al2O3 was also good, but silica and kieselguhr were not proper carriers for the object reaction, because of their stronger surface acidity, which could result in the formation of polymer, jammed the micro pores of catalyst, and then resulted in its deactivation. Addition of Bi, Ce and Cu promoters could not improve the activity of catalyst, but La and Ba promoter could enhance the activity of catalyst apparently, and the Co was the best promoter, especially Co was impregnate in advance. It was attributed to that the pre-impregnated Co may occupy the micro pores of active carbon, and cover some bad functional groups on the surface of catalyst, so that the active and selectivity of catalyst could be enhanced obviously.

研究结果表明，Pd-Co/活性炭催化剂是目标转移加氢反应的最适宜催化剂，Pd-Co/γ-Al203效果也较好，而硅胶和硅藻土由于表面酸性较强，容易造成生成聚合物而堵塞催化剂微孔、使催化剂迅速失活；此外，添加Bi、Ce、Cu等助剂时对活性并无改善作用，而添加La和Ba助剂时可使Pd的催化活性有所提高，效果最好的是Co助剂，尤其是先浸渍Co的Pd-Co/C催化剂，原因是Co占据了活性炭的微孔、覆盖了某些对目标反应不利的官能团，使其活性和选择性都有较大幅度的提高。

目的：动态观察核因子－кB及胶质纤维酸性蛋白在外伤性癫痫模型皮层或海马的表达，探讨有关发病机制。

In fact, many prefer its mild acidic flavor to Kona's sometimes too-delicate taste.

事实上，许多喜欢它的味道科纳轻度酸性的，有时过于敏感口味。

Results showed that casein could be completely removed of by adjusting pH 4.6 and centrifuging at 1100g.β-lactoglobulin was absorbed by the cation-exchange resin eluented by phosphate buffer. Through limiting the quantity of acid whey, the purity concentration percent of immunoglobulin was above 80% determined by SDS-PAGE. The ratio of activity of immunoglobulin losing decreased in simulated pepsin and the residual immunoglobulin content percentage was about 80% in 60 minutes.

实验结果表明：调节脱脂牛初乳pH=4.6采用1100g低速离心即可达到完全去除酪蛋白的良好效果；利用含有磷酸根基团的缓冲液处理阳离子树脂柱会专一吸附酸性乳清中的β—乳球蛋白，达到分离乳清中免疫球蛋白与β—乳球蛋白的良好效果，控制乳清样品处理量可使免疫球蛋白纯度达到80%以上；微胶囊化的免疫球蛋白可以延缓胃液对免疫球蛋白的消化分解，减缓免疫球蛋白活性损失速率，在60分钟内仍可保留80%的活性。

We compared the spectral and its secondary structure of endostatin with and without of zinc, heparin and lanthanides. It demonstrated that the pH has strong effect on the interaction of endostatin and heparin.

研究了内皮抑素与锌离子、肝素、稀土离子作用后蛋白质的光谱学性质和二级结构的变化，首次发现偏酸性pH对肝素与内皮抑素的结合作用有特殊影响，为研究内皮抑素特异抑制肿瘤组织新生血管的生成提供了实验依据。

However for P supply, DAP was found superior source and rock phosphate tended to be equally effective source of P in acid laterite soil.

不过对于磷素供应来说，磷酸二铵是最好的来源，磷矿粉在酸性红壤土上同样有效。

Except for HIMU-type OIB with negativeΔ7/4 ratios in the Wandashan massif, all other rocks have positiveΔ7/4 andΔ8/4 values, a feature of the Laurasia continent in the Northern Hemisphere.2 In the southern Hinggan Mountains distributes a Cretaceous felsic igneous rock belt characterized by highly positive-ε_ T_(DM = 0.42～0.64Ga,ε_ =+4.0～+5.9 and radiogenic Pb ~(206Pb/~(204)Pb = 18.36 ~ 18.56 isotope compositions.

除完达山外来拼贴地体的HIMU型OIB具有负的△7/4值，东北地区中生代火成岩都为正的△7/4和△8/4值，显示出亲北方劳亚大陆的岩石圈属性。2在大兴安岭南区林西-霍林河地区存在一条近似平行索伦-贺根山-小兴安岭古缝合带的高ε_早白垩世中酸性火山岩组合。

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。
