The ordered mesoporous material MCM-41 was synthesized by a hydrothermal method using fumed silica,sodium hydroxide/tetraethyl ammonium hydroxide/hydrogen chlorideand cetyl trimethl ammonium bromide.

用X射线衍射、氮气吸附-脱附等手段对比分析了合成的3种MCM-41介孔材料的物相、比表面积、孔径、孔体积等，发现酸性介质中合成的介孔材料的孔径最大。

Up to now, only a few well-defined metal complexes have been found to be able to hydrolyze DNA phosphodiester bond.

迄今为止，人们仅发现了为数不多的能够水解断裂DNA的磷酸二酯键的金属配合物。

Through our detailed researches on 11 viral strains, we found that they share common molecular characteristics, such as an icosahedral shape, and a dsDNA genome.

对病毒分离物中的11株病毒进行了较为详细的研究，发现这些病毒具有许多相同的性质，如均为球形多角体，基因组为300kbp左右的dsDNA。

I examined thoroughly looking for fragments of the UFO's crystals imbedded in the wing but found nothing.

我彻底地在机翼中找寻不明飞行物水晶镶嵌的碎片但是什么也没有发现。

Comparation on the recognition of three complexes:〓,〓 and 〓 suggests that, thought all of them can intercalate into sheared sequence with specificity, they tend to intercalate at different site.

通过对三种配合物〓，〓和〓的识别情况进行对比发现，它们对错配序列都可以进行特异性识别，但是各自的优先识别位置并不相同。

The results showed:intercomparison sequence from Exonl to part Intronl fragment amplification by primers 1 of two individual selection from each swinery with pig L-FABP gene sequence published in GenBank,found that base site of 237、258、315 of all individuals were A、T and A respectively,different with DQ182323 base sequence of G、C and C,and existence G403A mutation between individual.

结果表明：引物1扩增的外显子1到部分内含子1片段每个猪群选择两个个体经测序得到的序列与GenBank上已发表的猪(DQ182323)的L-FABP基因序列比对，发现所测所有个体237位点、258位点和315位点碱基分别为A、T和T与DQ182323序列的碱基G、C和C不同，而且所测个体间存在G403A突变。

Glacial and interglacial periods,rather than on the more usual modern method of studying biological

质事件，而是依据为普遍的现代方法，去研究间冰层中所发现的生物残物，而

Rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits.

不471。是依据更为普遍的现代方法，472。去研究间冰层中所发现的生物残留物，而473。这些间冰层本身又在冰川沉积物发生间层化。

It was known that pyridine and Triton-x100 had a bad effect on the cell growth and lycopene production were studied. The results indicated that pyridine and triton-x100 inhibited cell growth and lycopene synthesis;β-ionone increased cell growth and lycopene synthesis when the concentration was 0.05 ml/L, but when the concentration became higher, there would be a decrease on the lycopene output; span-20 increased cell growth and lycopene synthesis effectively when the concentration reached 2.0ml/L, and the lycopene yield became 2.4×10~(-2) mg/L which was 3-fold than control.

研究了培养基中加入不同浓度的小分子效应物吡啶、Triton-x100、Span-20、β-紫罗酮、异烟肼对番茄红素产量的提高作用，结果显示培养基中加入很低浓度的吡啶(0.1ml／L)就会对菌体产生很强的毒害作用；triton-x100对类胡萝卜素的合成也有很强的抑制作用，试验的浓度为0.2ml／L到5ml／L，结果发现它对菌体的生长和番茄红素的合成都有抑制作用；β-紫罗酮在浓度为0.05ml／L时有很小的促进作用，而浓度升高就有了比较强的抑制效果；span-20在液体培养基中的加量为2.0ml／L时，对番茄红素的合成有很强的促进效果，产量达到了2.4×10~(-2)mg／L，比原始菌株产量提高了2倍，而浓度进一步增大就产生了很强的抑制效果。

By analyzing production process of Jinchuan Company, Jinhua Group, Jinni Group ,Hexibao Iron Works and Yongchang Power Plant,the author find that Jinchang eco-industry construction is with a more solid foundation, and technology, industry links, management, the state\'s macroeconomic policies are more flexible in industrial ecosystem.

在金昌市生态工业研究中，通过金川公司、金化集团、金泥集团、河西堡铁厂和永昌电厂的生产工艺以及工业代谢物综合利用分析，发现金昌市生态工业建设具备较为雄厚的发展基础，工业生态系统中工艺柔性、产业链接柔性、管理柔性、国家宏观政策柔性较强。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
