I went round by the garden, and laid wait for the messenger; who fought valorously to defend his trust, and we spilt the milk between us; but I succeeded in abstracting the epistle; and, threatening serious consequences if he did not look sharp home, I remained under the wall and perused Miss Cathy's affectionate composition.

我绕到花园里，在那儿等着这送信的使者；他英勇地战斗，以保护他的受委托之物，我们抢得把牛奶都泼翻了；但是我终于成功地抽出来那封信；还威吓他说如果他不径自回家去，即将有严重的后果，我就留在墙跟底下阅读凯蒂小姐的爱情作品。

We make chloroacetylaion to N-terminal of Asp, and then convert this compound to GD dipeptide by aminolysis. Followed the lipase -catalyzed peptide synthesis of RGD in aqueous water-miscible organic cosolvent is studied. We set up a new efficient reaction method to synthesize RGD tripeptide. The problem that peptide containing polar amino acid can not be synthesized readily in organic solvent was solved. We offer a new experimental proof for PPL-catalyzed peptide synthesis and make a more general analysis for the effect of some factors in theory.

采用氯乙酰基保护天冬氨酸，然后进行氨解生成GD二肽，利用猪胰脂肪酶催化合成RGD三肽，着重解决了亲水氨基酸/肽片段底物的溶解性与合成产率低的问题，建立了一种新的有效合成RGD三肽的反应模型，并探索解决了极性较强的氨基酸的酶促肽合成的问题，对脂肪酶催化合成肽的影响因素从理论上作了较全面的分析，为肽片段的缩合反应提供了一种新思路。

Amination reaction was carried out at temperature of 90℃ to 150℃ for 2h to 10h and then ashless dispersant of polyisobutylene succinimide would be obtained after dehydration with the operations of vacuum distillation and filtration.

结果发现，实验在N_2保护下进行，BPO／PIB质量比为0.035，MA／PIB摩尔比为1.3，反应温度为150℃，反应时间为12h，搅拌速率为250rpm，引发剂过氧化苯甲酰以丁酮为溶剂分六次，时间间隔为30分钟，均量地加入反应器时，烃化反应物聚异丁烯的转化率最高。

In some cases, the presence of authigenic chlorite on sand grains can inhibit the growth of pore-filling cements during diagenesis and preserve pore space for occupation by hydrocarbons.

在有些情况下，砂岩颗粒上有自生绿泥石，它可以在成岩作用期间抑制填隙的胶结物生长，并保护油气占据的孔隙空间。

The results show that in the presence of NaHCO3 as base and DMF-H2O (volume ratio 2∶1) as solvent, the complex could catalyze not only iodobenzene but also non-activated bromobenzene quantitatively at 90 ℃ without the inert gas protection, and furthermore the catalyst could be recovered and reused more than eight times.

结果表明，在没有惰性气体保护的情况下，以NaHCO3作碱，以DMF水溶液(体积比为2∶1)作溶剂，在90 ℃时，该配合物不仅对活性较高的碘代苯能够定量地催化，对未活化的溴代苯也能定量地催化，并且催化剂能够回收再利用8次以上。
