The cell in acidic situation presented a degenerative chang-ment,such as an increased lipid drop and empty cavity in the cell plasma,a py-knotic nuclei,the dilatation of the endoplasmic reticulum and Golgi saccules,mi-tochondrial swelling the number of ribose decrease,and the ribose dissociated inthe plasma,a lot of swallowing cavity,the fibric material decreased accompany-ing with the acid being stronger.

随培养基pH逐渐下降，上述过程因受酸性阻抑而延缓，细胞增殖速度也受影响，处于酸性环境中的软骨细胞呈退行性变化，表现为细胞浆内脂质颗粒与小泡增多、细胞核皱缩、核仁浓染、内质网线粒体膨胀、核糖体数目减少，且与粗面内质网结合的少，游离在胞浆中的多。

In this article, the effect of different water pH (pH 5, 6, 7, 8, 9)on the secretion of nacre of freshwater pearl mussel Hyriopsis cumingii were studied with histochemical methods and transmission electron microscopy.

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。

In acidic soils, its toxicity is considered to be the most limiting factor for plant productivity.

全世界有39.5亿hm~2酸性土壤，其中可耕土壤面积为1.79亿hm~2，如何解决酸性土壤的铝害问题已经是不容忽视的一项重要课题。

From an early age, we should keep bones and muscles on the move with weight-bearing exercise.

这种喷雾可以增加鼻子内部的酸性，而感冒病毒是无法在酸性环境下生存的。

Stool is dark green because of food residue from digestion by bile, and yellow bile and stool to become acidic, post-discharge contact with air, and occasionally will become green; general breast-feeding stool easily biased acidic, it could become the Green discharged.

大便墨绿色是因为食物残渣经胆汁消化，而胆汁是黄色并使大便成为酸性，排出后与空气接触，偶尔会变成绿色；一般喂母乳的大便容易偏向酸性，可成为绿便排出。

Green stool is because by the bile to digest food debris, and yellow bile and stool to become acidic, post-discharge contact with air, and occasionally will become green; general breast-feeding stool easily biased acidic, it could be a green discharge, and now because of infant milk formula composition closer to breast milk, so it will be green, do not worry, as long as the stool can be normal traits.

大便绿色是因为食物残渣经胆汁消化，而胆汁是黄色并使大便成为酸性，排出后与空气接触，偶尔会变成绿色；一般喂母乳的大便容易偏向酸性，可成为绿便排出，现在因婴儿的配方奶粉成份接近母乳，因此亦会有绿便，不必担心，只要大便性状正常即可。

Eight dominant strains that can effectively degrade acidic material in landfill leachate were selected to investigate their degradation of benzoic acid, phenol, phthalic acid, fatty acids and so on in landfill leachate.

分离筛选能够快速降解垃圾渗滤液中难降解有机酸性物质的优势菌种8株，研究了这8菌株及其混合体对苯甲酸、苯酚、邻苯二甲酸、脂肪酸等以垃圾渗滤液中常见的有机酸性物质的降解特性。

This neutralises the acid and decreases the acidity of the stomach contents.

碳酸钙通过与胃液中过多的胃酸结合，中和酸性物质，降低胃内的酸性。

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。
