Manganese oxides supported on SBA-15 Mn(subscript xO/SBA-15 were prepared by incipient wetness impregnation of SBA-15 with furfuryl alcohol solution of manganese acetylacetonate or manganese nitrate followed by removal of the carbon resulted from carbonized FA.

采用溶液浸渍法将乙酰丙酮锰或硝酸锰的糠醇溶液分别灌注到SBA-15的孔道内，一定条件下将糠醇碳化后再将碳烧除，即可得到高度分散的MnO/SBA-15复合催化剂。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。

In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3-phosphate, the first step in the Calvin cycle.

在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3－磷酸甘油酸，这是卡尔文的循环第一步。

The latter is hydrolyzed in the acidic conditions, then the recovered copolymer of EO and glycidol with multi pending hydroxymethyls is esterified with 2-bromoisobutyrylbromide to produce the ATRP macroinitiator with multi pending bromoisobutyryl groups .

Based on this monomer, several novel polyimides bearing side chain s composed of cyano-biphenyl mesogenic end groups and hexylene spacer were prepared.

合成了一种含氰基联苯氧基侧链的二元胺单体，然后通过两步法热酰亚胺化工艺制备了新型的含氰基联苯基团侧链的聚酰亚胺。

The amphiphiles, 4-8, can not form reverse bilayers in organic solvent, which result in that the molecular interactions unable to meet the need for hydrophile-lypophile balance, so that they crystallize and exhibit no gelling abilities. The mono-chained L-alanine derivatives, 1-3, can self-assemble into bilayer aggregates, through intermolecular hydrogen bonding and homochiral effect in a number of organic liquids, which are juxtaposed and interlocked by van der Waals interaction, and finally gelate the organic liquids.

单链酰基化L-丙胺酸两亲物1-3在一些低极性的有机溶剂可以通过分子间氢键相互作用及同手性聚集作用形成有序的反双分子膜结构，这些有序反双分子膜结构单元依靠vander Waals力相互作用可以平行排列且相互之间进行连结形成长纤维状的聚集体，纤维状聚集体在有机介质中可以进一步相互连结形成三维网状结构，进而胶凝有机溶剂。

Results CsA clearly decreased creatinine clearance and increased urinary excretion of N-acetyl-β-D-glucosaminidase in rats as compared with those in the vehicle group. Morphologic changes consisted of vacuolization of tubular cell, expansion of the interstitium and interstitial fibrosis, hyalinization of afferent arterioles. Severity of the injury was related to the dosage of CsA. Striped interstitial fibrosis and arteriolopathy were more severe in the rats treated with CsA and low-salt diet than with CsA and normal diet.

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
