From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

1,After transfected the mutated mtDNA of colorectal carcinoma,the mtDNA D-loop region of the transfected cells displays new mutation points.2,The external source pieces of the mutated mtDNA can integrate to nuclear genome after transfection.3,There's no differences in apoptosis between combinations after transfected the mutation of mtDNA in NIH3T3 and LST cells.4,The mutated mtDNA may affect the action mechanism of occurrence and development in colorectal carcinoma through affecting its mtDNA mutation or integrating exogenetic mtDNA to its nuclear which may cause the abnormal expression of oncogene or anti-oncogene.

（1）转染突变的大肠癌细胞mtDNA后转染细胞的mtDNA均可发生多处的突变位点。（2）通过转染后突变的外源性的mtDNA可以整合到核基因组内。（3）突变的mtDNA转染LST细胞及NIH3T3细胞后，不影响转染细胞的凋亡改变。（4）mtDNA的突变可能通过影响体细胞mtDNA的突变和通过外源性mtDNA在核内的整合从而影响癌基因或抑癌基因的表达异常，从而参与肿瘤的发生发展。

Two pathways may belong to the same functional system, though they have some architectural difference. It has been disscussed that some neural structures in the visceral afferent pathway may have some relation to the somesthetic afferent.

在梭形细胞的树突上见到较多的对称性突触，突触前末梢含有多形性囊泡；在卵圆形细胞的远核区和树突上，常见到含圆形囊泡的末梢，与胞体和树突形成不对称性突触。

The results showed:(1) The histological changes of KC were in fact a wound-repair process;(2) The increased melanin in KC coordinated with "multi-overlapping screen" effect, a result of multiple layers of "supranuclear cap", was the direct cause of hyperpigmentation of the graft and (3) The hydrolytic disturbance of melanin in KC and the longer life span of the KC were probably the important reasons for the increase of melanin in the epidermis.

结果表明，角朊细胞的组织学改变实际上是一个损伤后修复的过程；角朊细胞内黑色素含量增加及出现的多层次的&核上帽&状分布而形成的&多重帘幕&效应，是皮片过度色素化的直接原因；黑色素在角朊细胞内的降解障碍及角朊细胞更新周期延长可能是表皮内黑色素含量增多的重要原因。

Spinach and other green, leafy foods provide tons of vitamin A, too, which helps your skin produce more fresh new cells and get rid of the old ones, reducing dryness and keeping your face looking bright and young.

菠菜和其他绿色的、多叶的食物能提供大量维生素A，也有助于你的皮肤产生更多的新鲜细胞和除去旧的细胞，缓解皮肤干燥，使你看起来年轻又有光泽。

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。
