本论文首次通过阴离子开环共聚，成功地将POSS大分子作为多官能团单体，与环硅氧烷在KOH硅醇盐或Me_4NOH硅醇盐等碱性催化剂的作用下，直接合成交联聚硅氧烷：通过调节POSS大分子和环硅氧烷单体的种类以及化学计量比，可合成出一系列不同种类和不同交联密度的交联聚硅氧烷；并对其阴离子开环共聚机理以及极性调节剂DMAc对凝胶时间的影响进行了详细讨论；同时借以凝胶含量和溶胀比、GPC、FT-IR、固体~(13)C和~(29)Si NMR、WAXD、DSC以及TG等手段对所得聚合物的微观结构以及热性能进行了详细考察。

As the first attempt, it was designed to reveal the general pattern of lectin receptor distribution on the surface of female cells, namely egg cells, central cells and synergids of Torenia fournieri and, especially, toensure the possible effects of cell isolation procedure on the distribution of lectin receptors by four different systems.

在烟草活体的中央细胞及卵细胞表面发现了伴刀豆凝集素受体的极性分布或者称之为&镶嵌性分布&。在大部分的中央细胞膜表面，该凝集素受体主要分布在靠近核的部位，而在相对侧的荧光要弱或缺失。

It is easy to fall into a practical craziness of utopianism according utopian social ideal, resulting to despotism and autarchy necessarily, while it will also deprive human beings of social ideal with transcendentality, ultimateness and comprehensiveness to resist utopianism completely, displaying a 'desert' of mediocre and despairing.

按照乌托邦的社会理想来建构现实社会，容易使人们陷入乌托邦主义的实践狂热中，专制与独裁是其必然结局，然而，完全拒斥乌托邦又会使人类的社会理想失去超越性、终极性和总体性，展现出来的就是一片平庸不堪和绝望无计的&荒漠&。

The results indicate that the method is simple and rapid for the determination of strong polar trigonelline in Trigonella foenum-graecum L. Furthermore, it significantly reduces the equilibration time compared with ion-pair liquid chromatography recorded in the Pharmacopoeia of China. This new method can be used as a valid method for the quality control of Trigonella foenum-graecum L.

结果表明所建方法分离效果好、快速简易，可以弥补中国药典中离子对色谱法平衡时间过长的缺陷，适用于胡芦巴药材中强极性胡芦巴碱的测定，为胡芦巴的质量控制提供了有效的方法。

Below its critical micelle concentration, SDS effect facilitated the energy transfer from the component at 232 nm to the tyrosyl residues in PS II proteins, and also resulted in less micropolarity for tyrosyl residues, whilst at or above its cmc, SDS had an opposite effect.

低于其临界胶束浓度时，SDS会促进蛋白质中232 nm外的组分与酪氨酸之间的能量传递，并且使酪氨酸残基外于极性更小的环境；而大于cmc时，SDS却产生相反的效应。

The stratification shows, as expected, that for this 8 sunspot, its stratification of the vectormagnetic fields has the main features of this kind: one umbra with positive polarity and the other with negative polarity; and the magnetic field vectors in the penumbra part between the two umbrae are more horizontal than those in the umbrae.
