Purified protein samples were separated by 2-DE with 17 cm IPG strips, and the protein spots were detected by fast silver staining. Six protein spots were randomly excised from the silver stained gel for primary analysis by MALDI-TOF MS. Four proteins were identified, and they were 1-aminocyclopropane-1-carboxylate synthase 2, ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit, F11O4.2 and Rubisco small subunit.

根据预实验结果，选用17 cm IPG预制干胶条对纯化的蛋白样品进行2-DE实验，采用快速银染法进行染色，随机挖取银染胶上6个蛋白点进行MALDI-TOF MS分析和数据库检索，鉴定了3个蛋白，它们是：1-氨基环丙烷-1羧酸合酶2，核酮糖-1，5-二磷酸羧化酶/加氧酶大亚基和F11O4.2。

Within this study, we found some interesting results, for example, the type of ring opening mode of methylene cyclopropyl ketones was changed from distal to proximal under the catalysis of palladium with the addition of two equivalents of sodium iodide.

我们发现了一个非常有趣的现象：亚甲基环丙烷基酮的开环方式可以得到有效的调控：在没有外加卤离子的情况下，开环方式为distal断裂，从而得到了4—氢吡喃化合物，而在两当量的碘化钠的存在下却发生了proximal断裂，从而能够得到2，4—双取代的呋喃。

With the size of alcohol ROH increasing, space steric block made solvolysis activity of propylene oxide decrease.

空间位阻的变化，使得环氧丙烷溶剂解反应活性随着醇类溶剂的分子增大而减小。

Effect of hydrogen peroxide concentration, acid or base adding in the raw-material, different solvent, etc. on solvolysis of propylene oxide in aqueous solutions was studied.

研究了双氧水浓度、原料中添加的酸或碱性物质和溶剂种类等因素对环氧丙烷溶剂解反应的影响。

He minim acidity in TS-1 can catalyze the solvolysis reaction of PO to propylene glycol, 1-methoxy-2-propanol and 2-methoxy-1-propanol.

S-1中含有的微量酸中心能够导致环氧丙烷与溶剂反应生成丙二醇、1-甲氧基-2-丙醇和2-甲氧基-1-丙醇。

Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW, a novel titanosilicate with the MWW structure, to synthesize epichiorohydrin selectively and effectively. Ti-MWW proved to be superior to the conventional TS-1 catalyst in both catalytic activity and product selectivity. Ti-MWW prefers aprotic solvents of acetone and acetonitrile, both of which can restrain the solvolysis of epichiorohydrin, whereas TS-1 favors a protic solvent of methanol.

研究了具有MWW结构的新一代钛硅分子筛Ti-MWW催化剂对烯丙基氯液相环氧化高效合成环氧氯丙烷的催化性能结果表明，Ti-MWW的催化活性以及产物选择性均优于传统的钛硅分子筛TS-1，对于Ti-MWW，合适的溶剂为非质子性溶剂丙酮和乙腈，在该溶剂中环氧化物不易发生溶剂化开环反应；而对于TS-1，合适的溶剂是质子性溶剂甲醇，但甲醇可导致醇醚副产物的生成。
