褐藻酸

Low molecular weight mannuronic acid, guluronic acid and κ-carrageenan were prepared from algin and carrageenan by the acid hydrolysis method, and their weight average molecular weights and the distribution widths of molecular weight were determined by high performance gel permeation chromatography respectively.

本文以褐藻胶和κ-卡拉胶为原料通过酸水解分别获得了低聚的甘露糖醛酸，古罗糖醛酸和低聚κ-卡拉胶，并采用HPGPC法测定了这3种低聚糖的重均分子量。

成分：硫锌酸、银杏精华、咖啡豆精华、大西洋褐藻等。

The molar ratio of sulfate ions to carboxylate ions is determined by conductometric titration method and the molecular weight is tested by high performance gel permeation chromatography. The precision of these two methods is also studied. To improve the detection sensitivity, guanidine hydrochloride is used as the best derivation reagent of 911. A systematic research is done on the optimum derivatization condition of 911 and Guanidine hydrochloride. The M /G ratio of 911 has direct relation to its biological activity.

论文首先对911的基本理化性质进行了系统的分析，以电导滴定法和高效凝胶渗透色谱法分别测定了分子中硫酸根羧酸根的比值和911的分子量，并探讨了两种分析方法的精密度。911分子没有紫外吸收，为提高检测灵敏度，本文采用荧光标记法，通过对三种荧光试剂与几种寡糖和多糖衍生效果的综合比较，最终确定了盐酸胍为最佳衍生试剂，并以911为代表详细探讨了衍生化反应的最优条件。911糖链结构与褐藻胶主链结构类似，以甘露糖醛酸和古罗糖醛酸的嵌段形式存在，分子中M/G比值与911的物理化学性质和生物活性有直接关系。

Such pregelatinized flours are sometimes blended with guar flour or alginates.

这种预糊化面粉有时也混合以瓜尔豆面粉或褐藻酸盐。

Experiments were also performed to study the IIF behavior of microcapsules of various sizes by the cryomicroscope. It was observed that the microcapsules behaved as osmometers that water migrated across the cell wall when there was an osmotic potential. During freezing, IIF phenomenon of microcapsules occurred immediately after the ice front touched the microcapsule following the seeding of the supercooled solution.

在本研究中亦以褐藻酸钠为材料制作不同大小微胶囊以模拟人工细胞，并以低温显微镜系统进行其低温冷冻实验，实验结果显示微胶囊会因为内外渗透压不同而发生水分迁移现象，且当触发囊壁外过冷水溶液时，囊壁外冰晶形成会随即造成微胶囊发生细胞内冻结现象。

In this paper alginate oligosaccharide and fucoidan oligosaccharide were prepared and their abilities of eliciting the defence reaction were studied.

本文以海带为原材料，制备寡褐藻酸钠和岩藻寡糖，用于诱导烟草抗病性的研究，结果如下。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
