After careful analysis and experiments, we successfully put forward a strategy that can be used to quantitatively determine the glycosyl residue compositions of acidic polysaccharides and other uronic acid-containing glycoconjugates.

经过仔细分析与实验，我们建立了一种新的测定酸性多糖糖残基组成及其比例的分析方法，我们称之为&糖组成分析的新两步水解法&。

Black fungus acidic heteropolysaccharide mice by intraperitoneal injection experiment results show that the polysaccharide has the promotion of white blood cells increase, anti-coagulation and reduce the role of platelets and its activity as the polysaccharide molecular weight and uronic acid content decreased and increased, namely, biological activity depends on the polysaccharidesolubility in water.

黑木耳酸性杂多糖小鼠腹腔注射试验结果表明，该多糖具有促进白细胞增加，抗凝血和降低血小板的作用，其活性随着多糖分子量和糖醛酸含量降低而增大，即生物活性依赖于多糖在水中的溶解度。

Results Using different concentrations of 5fluorouracil to deal with A549 cells, with the increase in drug concentration and treatment time,cell survival rate decreased significantly;and low concentration of 5fluorouracil induced the cell spread and increased vacuolization within the cytoplasm, acridine orange staining showed an increase in acidic vesicles,high concentration made the cell round and cell apoptosis.

结果不同浓度的5氟尿嘧啶处理A549细胞，随着药物浓度的增加和处理时间的延长，细胞存活率明显下降；且低浓度使细胞呈铺展状态，细胞质内空泡增多，吖啶橙染色显示酸性膜泡增多，高浓度使细胞变圆，出现凋亡状态。

The strong acidity, Fe(superscript 2+) and rather lower concentration of alkalis ions are responsible for voltaite, not jarosite, crystallizing from the acidic iron-bearing water.

分析认为，废液呈强酸性、溶液中存在大量Fe(上标 2+)、碱金属离子含量偏低是蒸发结晶过程中形成绿钾铁矾而不是黄钾铁矾的主要原因。

Recuperation ratio of silica xerogel is high, chemical stability of silica xerogel in acidic solution is very strorg.

研究了SiO〓纳米干凝胶的再生率和在酸溶液中的稳定性，结果表明SiO〓纳米干凝胶的再生率较高，在酸中的稳定性强。

Xylanases applicating in different fields have various zymologic characters, for example, alkaline xylanase can be used in pulp processing, while acidic xylanase is more suitable in feed industry.

用于不同领域的木聚糖酶对其酶学性质有着不同的要求，如纸浆工业需使用碱性木聚糖酶，而饲料中酸性木聚糖酶更适合。

Acid rain has a pH of 2or less and is responsible for acidifying streams and lakes and ,thus,not only killing fish but leaving the waterway too acidic to be reinhabited.

酸雨的酸碱度小于或等于2，它导致溪流和湖泊的酸化，因而不仅杀死鱼类而且导致水域过酸而不能再在其中居住。

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.
