Methods The experiment was carried out based on theory and methods in chemistry; According to the membrane performance, the membrane water solubility, and other characters, the author took experiment on the alginic acid sodium, chitsan, the gelatin and other biological materials.

参照化工学的理论和方法，进行实验研究；从海藻酸钠、壳聚糖、明胶等生物相溶性较好的物质中，依据反应成膜性能、膜的水溶解性和生物相溶性，以及自身流动性和表面接触角度等特点，先进行组分筛选，再行研制确定。

Results Through the experiment by membrane performance, the alginic acid sodium met the requirement, which became the membrane with the CaCl2 reaction at once. Its membrane was not dissolved in the water. And the characters of its 1%-3% solution were good on fluidity and surface contact angle determines. The biological compatibility of the compound of it with 20% CaCl2 solution was good.

结果：通过成膜性筛选实验，发现只有海藻酸钠符合要求，其与CaCl2反应能瞬间成膜，其膜不溶于水；通过测定其流动性和表面接触角度等，发现其质量分数为1%~3%的水溶液各种性能较好；其与质量分数为20%的CaCl2溶液反应成膜的生物相容性较好。

The in vitro drug-release tests of the microcapsules were studied and the inhibition toward Staphylococcus, Hay Bacillus and Escherichia coli by their extravasates respectively were also performed via pervasion method.

方法是将头孢唑啉钠溶于海藻酸钠的PBS溶液，用正己烷／Span-85乳化形成微乳溶液，然后用CaCl2单凝聚固化得头孢唑啉钠的微胶囊；利用扩散法研究了该微胶囊渗出液对金黄色葡萄球菌、枯草杆菌和大肠杆菌的抑制作用。

In order to preserve the color of fresh-cut peach fruits and extend its shelf life, effects of three kinds of edible coatings（carrageenan, carboxymethyl cellulose, sodium alginate）and their combinations in two of them on qualities and oxidase activities of fresh-cut peache fruits during storage at 5℃ were investigated.

为了保持鲜切桃块的色泽，延长其货架期，试验以久保和绿化9号桃为材料，研究了卡拉胶、羧甲基纤维素、海藻酸钠涂膜及其两两复配处理对鲜切桃在5℃下贮藏期间的色泽及多酚氧化酶活性变化的影响。

The OD of sodium alginate enhanced along with the increasing amounts of added sodium periodates. The molecular weights of sodium alginate were also declined as reaction temperature rising.

结果证实氧化温度上升时，氧化产物的相对分子质量显著降低；增加氧化剂量可获得较高氧化度的氧化海藻酸钠，但同时也降低了氧化产物的相对分子质量。

These photocrosslinked alginate hydrogels, with tailorable mechanical properties and degradation rates, may find great utility as therapeutic materials in regenerative medicine and bioactive factor delivery.

这种具有可调的力学性能和降解率的光交联海藻酸盐有望作为治疗材料广泛应用于再生医学和生物活性因子的转运。

The experimental results match the theoretical calculation well. The formula of theoretical calculation can be widely applied to study the effect of physicochemical properties of alginate and parameters of electrostatic droplet generator on diameter of gel microspheres of calcium alginate.

采用静电液滴发生器制备海藻酸钙凝胶微球，研究了液滴形成机理、微球形态和粒径变化，并通过理论推导得到了微球粒径的计算公式，其计算公式能够很好的吻合实验结果，具有普遍的适用意义。

BACKGROUND: Based on documents abroad and home, both alginic acid and carbomer are used to prepare gel matrix of lithium carbonate tablets; furthermore, hydroxypropyl methyl cellulose, a kind of water-soluble skeletal material, can be used as controlled release matrix of lithium carbonate tablets.

摘要背景：目前国内外文献报道的碳酸锂缓释片多采用海藻酸、卡波姆等制备凝胶型骨架片，同样作为水溶性骨架材料的羟丙基甲基纤维素，也可作为碳酸锂的缓释基质。

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。
