In this thesis, we did modifications of alkyl groups upon benzyl fluorophosphonate. In order to study the influence of alkyl length and steric effect on activity and selectivity of probes, we synthesized benzyl fluorophosphonate recognition heads with modifications including ethyl, butyl, octyl and cyclohexyl. By way of connecting different kinds of tag like azido group, biotin and rhodamine with recognition heads separately through a higher hydrophilic ethylene glycol derived linker, a series of benzyl fluorophosphonate probes were made up. And they will apply to various biological testing strategies.

在本论文中，我们以苯甲基氟化磷酸酯为基础，於其上进行一系列烷基之修饰，为了探讨烷基长度与空间立体性质对於探针活性及选择性的影响，我们合成了包含乙烷基、丁烷基、辛烷基以及环己烷基修饰的苯甲基氟化磷酸酯辨识端，并藉由具较高亲水性的聚乙二醇衍生连接桥结合三种不同的发报端，分别有叠氮基团、生物素及萤光基团来构成不同的化学探针组合，这一系列苯甲基氟化磷酸酯类化学探针将可被应用於不同的生物测试策略。

In present study, a liquid-liquid extraction method was employed to extract the volatile components in mulberry fruit sparkling wine. The analysis with gas chromatography-mass spectrometry detected 69 peaks, among which 63 volatile components were identified. The first 9 volatile components with high relative content were benzyl alcohol, 2-methyl-1-butanol, mono-(2-ethylhexyl)-1, 2-benzene dicarboxylic acid, 3-methyl-1-butanol, toluene, acrylic acid butyl ester, 1H-indole-3-ethanol, isodecyl octyl phthalate and decyl octyl phthalate.

采用液－液萃取法提取桑椹汽酒中的挥发性成分，经气相色谱－质谱联机分析，共检测出69个峰，鉴定出63种挥发性化合物，其相对含量排在前9位的挥发性化合物分别是苯乙醇、2-甲基－1-丁醇、1，2-苯二酸单（2-乙基）己酯、3-甲基－1-丁醇、甲苯、丙烯酸丁酯、1H-吲哚－3-乙醇、邻苯二甲酸异癸基辛基二酯、邻苯二甲酸癸基辛基二酯。

The results show that the foamable MAA/MAN copolymers were prepared at 40-60℃ by polymerizing the mixture of 50phr MAA, 50phr MAN, 1-5phr magnesium oxide, 2-8phr butanol and tert-butanol, 0.2-0.3 phr dibenzoyl peroxide and tert-butyl perbenzoate and 0.1-0.2phr DMF. Then the resulting copolymers were expanded at 200-220℃ for 2-3h, subsequently treated at 160℃ for 5-6h, generating PMI foams with excellent mechanical properties and heat-resistance.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
