The reaction process in methanol solvent can be deduced from the computational results with CPCM solvent model and the supermolecular handling, namely the reaction involves four steps in the methanol solvent. The nucleophilic addition of trimethylamine to acraldehyde generates an enolate. Nucleophilic attack of the enolate on the aldehyde forms the carbon-carbon bond, followed by the proton-transfer process and the further elimination generating the product and liberating the trimethylamine catalyst.

对于CH3OH对反应体系的影响，可以综合考虑CPCM溶剂模型及超分子模型下的研究结果，即CH3OH溶剂中反应按四步进行，催化剂三甲胺首先与丙烯醛发生亲核加成，生成的两性离子中间体与甲醛发生类似于Aldol的醛醇缩合，形成碳-碳键，之后发生分子内质子转移，最后经E1cb消除得到产物，并释放催化剂三甲胺。

以合成的活性季铵盐改性了N，O-羧甲基壳聚糖、N，O-1-羧乙基壳聚糖(N，O-1-CEC)、N，O-2-羧乙基壳聚糖(N，O-2-CEC)、N-羧甲基壳聚糖和N-1-羧乙基壳聚糖(N-1-CEC)等羧烷基壳聚糖，得到5个系列25种具有两性高分子电解质特征的新季铵化羧烷基壳聚糖，其中24种为首次合成；创新提出以微波辅助酸催化的方法催化2-羟丙基二甲基苄基-N，O-(1-羧乙基)壳聚糖氯化铵(GDMBA-N，O-1-CEC)水解，得到了低分子量的GDMBA-N，O-1-CEC。

The dentofacial characters of Class II division 1 in our samples,there were not only the different size between sex but also the wholeappearances. Because of that we defined there was sexual dimorphism in our samples.

的研究样本中除了有大小不同的差距，另外在整体的表现上也有性别的差异，因此我们认为本研究样本存在两性二形的情况。

Demonstrated by adsorptive capacity and adsorptive energy, polyacrylamides have strong interaction on mineral surface with similar action mode to that of starches, for example, hydrolyzed polyacrylamide and hydroxamic acid polyacrylamide mainly by chemical force, cationic polyacrylamide by electrostatic force and hydrogen bond, nonionic polyacrylamide by hydrogen bond, while amphoteric polyacrylamide embodying both the characters of anionic and cationic one.

聚丙烯酰胺类化合物在矿物表面的吸附能以及吸附量均显示出药剂与矿物间存在的强作用，作用方式与淀粉类药剂相似：阴离子聚丙烯酰胺、羟肟酸聚丙烯酰胺主要靠化学作用，阳离子聚丙烯酰胺借助静电力和氢键，非离子型的聚丙烯酰胺则主要是氢键作用，两性聚丙烯酰胺同时具有阴离子和阳离子聚丙烯酰胺药剂的作用特点。

In the next chapter, the essay reveals the courses of the medieval gender discourse by using the concept of Foucault's discourse, and analyzes newly the influences of such historical phenomena as ecclesiastical law, virgin worship and courtly love on the shaping of female with such psychological concepts as Gender stereotypes, masculinty and feminity etc .

文章在第二部分运用福柯的话语概念，阐述了中世纪性别话语的来源，并借用心理学上的性别刻板定型、两性气质等概念，重新剖析教会法、圣母崇拜、典雅爱情等历史现象对女性性别塑造的影响。

Any of numerous usually marine and free-swimming coelenterates that constitute the sexually reproductive forms of hydrozoans and scyphozoans.

大量的、经常在海中自由游动的腔肠动物，它们组成水螅和钵水母的两性繁殖的形式。

Flowers bisexual; staminal filaments with an indumentum; gynoecium ± half as long as petals; seed coat with thick inner layer of dense black sclerenchyma and an outer layer of compact dull to ± shiny parenchymatous tissue.

花两性 花丝与一毛被一起；雌蕊群±一半与花瓣等长；种子对多少发亮的parenchymatous组织涂上厚内部层紧密的黑色的sclerenchyma 和一层外部的小型暗。

The amphoteric character of Al2O3/SiO2 can scavenge acidic hydrogen fluoride,which is inevitably present in the LiPF6-based electrolytes us...

膜中Al2O3/SiO2的两性特征，将电解液中的酸性HF消耗掉，而HF作为现在锂离子电池所用电解液中的杂质是不可避免的。

Sex education first appears on the compulsory curriculum when pupils between 11 and 14 years old learn the basics in science class; relationships, sexually transmitted diseases and the inadvisability of conceiving in one's teens are relegated to the optional "personal, social and health education".

当11至14岁的学生开始学习科学基础课程时，性教育才第一次出现在义务教育的课程中。两性关系、性传播疾病、未成年人怀孕的不明智做法被降级为一门"个人、社会及健康教育"的选修课。

This sets a scene of normative industriousness and gender separation: each is doing the work appropriate to his or her station, and they are not interacting in inappropriate ways.

这里设置了一套标准化的刻苦读书与两性隔离的场景：他们各做各的事，不以不适当的方式进行交往。
