The title compounds were prepared using chlororesorcinol and trimellitic anhydride as the starting materials in seven steps, with fine overall yields.

以氯代间苯二酚和苯三酸酐为起始原料经7步反应得到了目标化合物，产率良好。

The results showed that the addition leading to -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 7 could proceed with good diastereoselectivity and excellent yield (95%).(3) The selective N-deprotection of -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 2 without affecting the vinyl group in the substrate were untaken.(4) The Zip reaction for the transformation of -1-(3-aminopropyl)-3-methylazecan-2-one 8 to -7-Methyl-1, Sdiaza-cyclotetradecan-6-one 9 were undertaken. The results showed that, under controlled conditions, acceptable yields (43%) could be achieved and racemization can be minimized during the ring expansion reaction.

该合成路线与文献方法相比，反应条件较温和，也缩短了反应时间；(2)哌啶衍生物2与乙烯基格氏试剂进行加成反应的条件和立体选择性，取得了较好的结果（差向异构体比为80：20，产率95％左右）；(3)不饱和哌啶衍生物7在不影响碳碳双键的情况下去除苯基甘氨醇手性辅助基的条件；(4)具有羰基α位手性的氨基酰胺8在不同条件下经Zip重排反应转变为9的反应，控制反应条件，可使反应中消旋化减小到最小的程度。

The optimum conditions of reaction confirmed by orthogonal test design include reactant molar ratio of KMnO4: reactant=2:1, the reaction time of 4 h and acidifying time of 1.5 h with the yield of 94%.

经正交试验确定反应最佳条件为高锰酸钾用量为原料的2倍，反应时间4h，酸解时间1.5h，产率94%。

It focuses on journalists themselves and attempts to understand the interactive relationship of TV news workers, colleagues and managers though field study and in-depth interviews. Finally, I use grounded theory to analyze field information, concretizing the research subject and goals, with discussions of the model of news production in pack journalism.

本研究以「一窝蜂新闻学」为根基，并以以「记者一窝蜂动作」为经，「与同业、决策者的互动关系」为纬，并援引Bourdieu新闻场域理论与Giddens的结构行动论，解析造成一窝蜂新闻产制与新闻同质化的内、外在因素。

In particular the use of new-born eggs (ie, young chickens the first four months of birth to the eggs, egg yolk because of new-born are better protein quality)ú by ú Cooking ú decorticating special spices and then baking±úúú vacuum-packed high-temperature sterilization, the whole process about a week ago.

特别采用初生蛋(即青年鸡前四个月产下的蛋，因初生蛋的蛋黄蛋白品质都较好)→经蒸煮→剥壳→再以特制的香料卤制→烘焙→真空包装→高温杀菌，整个制程约一周之久。

A new method for enucleating MⅡ nucleus in mouse and rat was induced; Living births were obtained from IVF of mouse oocytes reconstructed by transfer of metaphase Ⅱ chromosomes. For the interspecies nuclear transfer between mouse and rabbit, the reconstructed embryos could develop into blasocyst in vitro.

在不同品系小鼠卵母细胞核质交换移植中将电融合的重构卵进行IVF，经胚胎移植后顺利产仔；在异种核移植方面，小鼠核与兔卵母细胞的异种重构胚在体外培养条件下发育至囊胚阶段。

Cultured giant seaperch was three-piece filleted to prepare meat paste of the ordinary muscle. Changes in gel strength of the meat paste heated at 30-80℃ for 20-120min were investigated. The gel strength increased strikingly and reached a maximum at around 50℃, which then decreased at 60℃. This indicated that suwari, a setting phenomenon occurred at 50℃ and modori, a disintegration phenomenon occurred at 60℃.

本研究以省产养殖活金目鲈为材料，经三片切取普通肉制备肉糊，将此肉糊於30-80℃处理20-120min时，发现在50℃以下低温域加热处理，随时间之延长英凝胶强度有逐渐上升趋势，而在60℃以上高温域加热处理时，则见明显下降趋势，显示金自鲈肉糊之低温凝胶现象(suwari； setting)发生於50℃，而高温解胶现象(modori； disintegration)则发生於60℃。
