The results showed that the mutant contained high trehalose content and high cell survival rate kept even after 4 h 18 %vol alcohol treatment (no respiration deficiency existed), which indicated that high trehalose content could protect cells membrane and prevent DNA loss of mitochondria and exosmosis of intracellular materials.

结果表明，中性海藻糖酶缺失突变株细胞海藻糖含量较高，用18 %vol的酒精处理4 h后仍可保持高的细胞存活率，并且无呼吸缺陷型的出现，说明高海藻糖含量可以保护细胞膜，防止线粒体DNA丢失和胞内物质的外渗，与酵母的酒精耐性之间存在一定的关系。

On the basis of study on the conditions and pathways of expression of cell totipotency , totipotent cells were inquired to found the clone of marine macroalga.

依据藻体类型和早期形态发生类型，选择假膜体、膜状体和多核单细胞体三种类型的海藻，在单藻培养、不加激素的条件下进行外植体培养，研究海藻细胞全能性表达的条件和途径，并在此基础上，寻找全能性细胞，构建大型海藻无性系。

The mechanism in which trehalose is produced from dextrin or starch hydrolyzate by endocellular enzymes of bacterium D-97 can be elucidated by high performance liquid chromatography with differential refraction detection basically, including the effect of the different carbon sources on the endocellular trehalose-producing enzymes in bacterium D-97 and the possibility or ability of the endocellular enzymes to produce trehalose using maltooligosaccharides of different chain lengths.

通过高效液相色谱/示差折光检测系统分析可获得细菌D-97利用糊精或淀粉水解物合成海藻糖的基本生物学信息，包括微生物培养碳源对细菌D-97胞内海藻糖合成酶系的影响以及该酶系利用不同种类或不同分子链长度的麦芽寡糖合成海藻糖的能力及作用过程。

The most obvious seaweeds are brown algae; mosslike carpets of red algae are seen at low tide s.

最常见的海藻是棕色海藻；在较浅的潮汐中能看到成片的苔藓般红色海藻。

First,through monofactorial experiment,we studied the influences of pH,temperature and substrate concentration on acidic trehalase activity of baker's yeast.

首先通过单因素实验研究了pH值、温度、底物浓度对面包酵母酸性海藻糖酶活性的影响，然后通过正交试验得出了酸性海藻糖酶活性测定的适宜条件：海藻糖浓度1.6%、温度30℃、pH 4.0、酵母菌泥接种量为0.02g/mL。

To test the influence of trehalose accumulation on response to freeze stress, we constructed all single and double gene disruption mutants of the trehalase genes ATH1, NTH1 and NTH2 and examined the changes of their trehalose accumulations and their freeze tolerance.

为了检测冷冻压力下海藻糖积累的作用，我们构建了海藻糖酶基因ATH1、NTH1和NTH2的各种单基因突变株和双基因突变株，并对突变株的海藻糖积累情况和耐冷冻能力进行了检测。

First, through monofactorial experiment, we studied the influences of pH, temperature and substrate concentration on acidic trehalase activity of baker's yeast. Then we designed an orthogonal experiment to detective the optimal condition of ascertaining acidic trehalase activity. The optimal conditions are: substrate concentration 1.6%, pH 4.0, temperature 30 and seed volume 0.02g/mL compressed yeast.

To determine the role of neutral trehalase during storage stability of spores, we constructed a M.anisopliae RNAi transformant and an overexpression transformant. Analysis of these transformants revealed that the expression level of the neutral trehalase gene in RNAi transformant(No 688) was reduced to 50% of which found in wild type and the overexpression transformant(No 113) showed approximatlely 2-fold higher levels of neutral trehalase mRNA than that found in wild-type control.

构建了中性海藻糖酶基因RNA干扰载体和超表达载体，采用电转法和基因枪法转化金龟子绿僵菌CQMa102，获得了RNA干扰转化子和超表达转化子，比较这两种转化子和出发菌株的mRNA表达情况，发现RNA干扰转化子中性海藻糖酶mRNA表达受到抑制，而超表达转化子中性海藻糖酶mRNA的表达量是出发菌株的2倍。

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。
