Nuclear DNA content analysis revealed that hybrid plants had different nuclear DNA content:higher,lower than the parental sum or equal to it.Contrast to the lower and equal hybrids,bigger amount of hybrids with higher DNA content had abnormal leaf,bad growth vigour and poor fertility.

结果表明：杂种形态变异广泛，多数呈中间类型，少数呈偏亲性状；杂种细胞DNA含量不一致，呈现大于、等于、小于双亲细胞DNA含量之和的类型；DNA含量大于双亲之和的杂种与DNA含量等于或小于双亲之和的杂种相比，有较高比例的材料叶型出现畸形和植株生长势弱，育性也更差。

Specifically, itcontains 8 chapters.In chapter 1, the formation, structures, properties and the futureprospect of liposome were thoroughly reviewed;In chapter 2, the stibility and permeability of phopholipid -eleostericacid liposome were studied together with the effect of polymerizationof eleostearic acid. This membrane system was very sensitive to 〓,the effect of 〓 was clarified to increase the aggregation/fusion ofliposomes and made the permeability of mixed liposomes much higher;In chapter 3, two polymerizable conjugated diyne bolaamphiphiles were synthesized. They could form very stable mixed liposome, andthe diyne could be polymerized by UV light in bilayer liposomes, as aresult, the stability of mixed liposome against solvent or surfactantafter polymerization were enhanced. In chapter 4, two kinds of amphiphilic amino acids were synthesized andstable liposomes were formed therefrom After the condensationpolymerization of amino acid in bilayer liposomes, stable polypeptide liposomes were obtained, which had lower phase transition temperatureand higher permeability.In chapter 5, four kinds of glycolipids were synthesized and theiraggregation behavior in water was comparied. When incorporated intophospholipid bilayer membranes, they could increase the phase transitiontemperatures and inhibit the aggregation and fusion of mixedliposomesat lower temperature.In chapter 6 and 7, three kinds of steroidal bolaamphiphiles withdifferent chain lengths were synthesized. Incorporation of steroidalmoiety to the center of lipid bilayer membrane obviously increased themobility of lipid membrane and shifted Tc to lower temperature side incomparasion with cholesterol. The bolaamphiphile which was shorter thanthe hosted lipid bilayer membrane thickness influenced the lipid packingmore obviously.

全文共分8章：第一章对脂质体的形成、结构、性质及展望进行了较为详细的文献综述；第二章研究了磷脂-桐酸脂质体的稳定性，通透能力及桐酸的聚合对这些性质的影响；磷脂-桐酸混合脂质体为一类对〓灵敏的脂质体，〓的作用首先是使脂质体集聚然后使脂质体融合，并加速内包荧光物的释放；第三章通过合成两种可聚合共轭双炔双极性双亲分子DDCA，DDOL，研究了共双炔分子在双分子层脂质体膜上的聚合及对脂质体性质的影响，聚合可以提高脂质体相对于溶剂及表面活性剂的稳定性；第四章合成了两类氨基酸为极性基团的双亲分子，它们均可以在超声下形成稳定的脂质体结构；氨基酸基团可以在脂质体上进行缩聚反应，若聚合后脂质体表面仍有足够的亲水能力，则可得到稳定的多肽型脂质体；聚合后脂质体的相变温度降低，通透能力增加；第五章合成了四种亲水基团为单糖基的双亲分子GL-l，GL-2，GL-3， GL-4，研究了它们在水中的分散情况、集合体形态与分子结构的关系；在DMPC双分子层膜中加入糖脂分子可以使脂质体的相变温度提高，阻止脂质体在低温放置时的集聚与融合；第六章-第七章合成了三种不同碳链长度的双极性含胆甾环双亲分子 CL-1，CL-2，CL-3；它们可以象胆固醇一样与磷脂混合形成稳定脂质体，胆甾环基团位于脂质体双分子层膜的中间；与胆固醇的作用相反，它们可以增加磷脂双分子层膜的流动性，降低混合脂质体的相变温度；三种分子的作用与其碳链长度和磷脂双分子层膜的厚度有关，比膜厚度短的分子影响最大。

The welfare homes and some social welfare institutions that also accept orphans oer guardianship and rearing mainly to children who have lost their parents during natural disasters or accidents, and also to those abandoned by their parents because they are seriously or almost irremediably disabled mentally or physically, or because they have contracted a serious illness.

儿童福利院和其他也监护养育部分儿童的社会福利院监护养育的儿童主要是因天灾和不可预测事故失去双亲的孤儿，同时也监护养育因身患难以完全康复的智残、肢残等重残或因严重疾病而被父母遗弃的儿童，目前，这类在院监护养育的儿童共有2万名左右，约占中国未成年人总数的十万分之五左右。

However, my recent interviews with children living in the group of islands that includes Tertia show that these children spend much more time talking about their biological parents than about other adults in the village.

然而，我最近对包含 Tertia 的一组岛屿上生活的儿童的采访显示，这些儿童的谈话中谈到他们双亲的时间要远多于谈到村庄中其他成年人的时间。

Field, a noted anthropologist, visited the island of Tertia and concluded from his observations that children in Tertia were reared by an entire village rather than by their own biological parents.

然而，我最近对包含 Tertia 的一组岛屿上生活的儿童的采访显示，这些儿童的谈话中谈到他们双亲的时间要远多于谈到村庄中其他成年人的时间。

The regiment was a home, too, and a home as unchangeably dear and precious as the parental home.

兵团也是他的家，也像双亲的家一样始终是可爱的、可贵的。

It is no doudt that many people are very kind and sad about the disaster is coming to China ,to left many local people dead.l compassionated the children lost their parent and become the orphan.

我同情那些那些失去双亲的孩子，一场天灾将他们变成孤儿。同时对于中国人这样团结起来拯救受灾人群的事情，我感到非常震惊。最后但并非最重要的是，如果我们不顾一切去救人，许多人依旧是可以活下来的。

NO! Bowser then mortgages his parents home by disguising himself as his own dad just to lose the money on a train to a nun!

为了筹集拍电影的资金，Bowser甚至以对家人隐瞒的方式按揭了双亲的房子，此举伪装得像是他父亲把一笔资金莫名地遗失掉一样。

I remember my father getting butcher paper, that was a pink, waxy butcher paper, and he would bring it home for me, sheets and sheets of it.

他将自己的艺术成就，归功于双亲的培养：我记得父亲带回来一些屠宰店用的纸，他把那些粉红色又好像涂了腊的纸给我，我就坐在地板上开始画。

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。
