The results showed that under 200 W power, in the present of various alkalis, e.g. Na2CO3, NaF, KF, NaHCO3, and DMF-H2O (V∶V=5∶3) used as solvent, PVC-TETA-Pd could catalyze sodium tetraphenylborate to react quantificationally with iodobenzene in 20 min without inert gas protection, and all the phenyl g...

实验发现：在微波功率为200W时，在Na2CO3，NaF，KF，NaHCO3等多种碱的存在下，以DMF的水溶液(V∶V=5∶3)为溶剂，在无惰性气体保护下，PVC-TETA-Pd催化四苯硼钠与碘代苯在20min内即可定量反应，与常规加热方式相比，节省了大量时间；同时也证明了四苯硼钠的四个苯基均可参与Suzuki偶联反应；该催化剂回收再利用3次后，仍具有较高的催化活性。

One route was that the amino-groups on the silica gel were transformed to tertiary amines by Eschweiler-clarke reaction that amine-groups react with formaldehyde and methanoic acid to prepare tertiary amines; the silica gel intermediates with tertiary amine groups reacted with chorohydrocarbons to prepare insoluble silica gel quaternary ammonium salt bactericides. Another route was that the amino-groups on the silica gel reacted with excessive chlorohexadecane; the preparing intermediates were quaternized with iodomethane to obtain insoluble silica gel quaternary ammonium salt bactericides.

一条路线是根据埃施韦勒-克拉克(Eschweiler-clarke)胺甲基化反应，进行胺基叔胺化反应，制成带有叔胺官能团的硅胶中间体，此中间体上的叔胺与卤代烷反应生成杀菌活性官能团季铵盐，制成硅胶类水不溶性季铵盐杀菌剂；另一条路线是带有胺反应活性中心的硅胶与过量正氯代十六烷反应，得到的中间体再用碘甲烷季铵化，得到最终产品——水不溶性季铵盐杀菌剂。

Indicate by an arrow the position most likely to react in each of the following three isomeric nitrotoluenes.

答：用箭头标出与硝基甲苯的三种同分异构体发生反应最有可能发生的位置并解释。

Considering, it is limited the cross-reactivity displayed by a single HVR peptide. We designed to ligate several high reactive HVR1 genes, and the recombinant fused protein containing several HVRls would have the ability to cross-react with most of HCV infected sera, and could be an effective immunogen of HCV vaccine.

但我们认为通过一条肽获得的交叉反应毕竟是有限的，故设想如果能将几个具有高交叉免疫反应性的HVR1片断用基因重组的方法连接起来，可能会获得与绝大多数病人血清发生免疫交叉反应性的抗原，并为疫苗的研究提供真正有效的免疫原。

And it also shows how unprepared, andmust react and speak quickly. Just likesome salespeople.

这同时也显示了他们必须在毫无准备和技巧的情况下快速反应及回答，这就像某些销售人员一样。

In the presence of linoleic platinum the ratios of W and S of breast cancer cell membranes and S180 cell membranes labeled with MSL were changed, The results indicate linoleic platinum can react with mercapto groups on the proteins of tumor cell membranes and change the conformations of cell membrane proteins.

亚油酸铂靶向脂质体的存在，使MSL的乳腺癌细胞膜和S180实体瘤细胞膜的W和S的比值发生了变化，结果表明亚油酸铂可以作用于癌细胞膜影响膜蛋白巯基结合部位，并使癌细胞膜表面蛋白质构象改变。
