单体

By the experimental study we can get the ways of this polymerization craft which is that we can construct water-solution foam polymeric system with the help of the foaming agent, using AM and DMDAAC as monomers, and that we choice the oxide-reductive agent and ultraviolet light as compound initiation system, and that we proceed vacuate pretreating for Pharmaceuticals, and superinduce additive to prevent cross link in drying process which also can improve product water-solubility.

实验研究得出这种聚合工艺的具体方法为：以丙烯酰胺、二甲基二烯丙基氯化铵为单体，在起泡剂的帮助下，构建出水溶液泡沫聚合体系，引发体系则选用氧化—还原剂和紫外灯组成的复合引发体系引发反应，药品进行抽真空预处理，同时添加一定量的助剂防止产品在干燥过程中发生交联，改善产品水溶性。

The results showed that the average particle size enlarged,but surface charge density and the latex stability decreased,if the monomer concentration increased.

实验结果表明，加大聚合体系中单体的质量分数，可以得到粒径较大的乳胶粒，但乳液的表面电荷密度和机械稳定性减小。

Hydrophobically associating water-soluble polymer-based synthesis is difficult and not easily characterized, in part to hydrophobic chains connected to the water-soluble polymer, the general use of micellar copolymerization, or the use of the large surfactant monomer to copolymerization, polymer micelles need in the system by adding a large number of surface-active agent, which, after an increase of the complexity of the process.

疏水缔合型水溶性高分子很难合成，且不易表征，把疏水部分连接到水溶性聚合物链上，一般采用胶束共聚合或者使用具有表面活性的大单体进行共聚，胶束聚合需要在体系中加入大量的表面活性剂，这就增加了后处理过程的复杂性。

According to the analysis of the ship forms and the design calculation,two design plans of the SWASH ship form and the simple moulded lines of one was developed out.

到了20世纪90年代有人出于两方面的目的对小水线面单体船进行了研究：改进水翼艇的快速性，减少小水线面双体船的阻力。

During this phase the homologous chromosomes undergo synapsis, or pairing, which is brought about by a bridging structure of proteins and RNA called the synaptonemal complex.

与有丝分裂不同的是，每组染色体的两个染色单体连接在着丝点上并一起移向细胞两极的一级。

Taking the syneresis as a ratio, the stabilities of seal-filling hydrogel after heated are investigated under this conditions, such as the different temperature of heating, initiator concentration and the heating time by experiments.

另外，材料的变形率与单体添加量、交联剂浓度、促凝剂含量有关，弹性模量出现阶段性的变化，且分界点一般出现在纵向形变为50%的点处。

The carbon isotope composition of single alkanes (δ13Cia) in two plants (Leontopodium leontopodioidies and Taraxacum mongolicum ) growing in the northeastern Qinghai-Tibet plateau was analyzed by means of GC-IMS in order to know its relationship with altitude,and furthemore, to gain new data for the research on climatic changes.

用色谱—同位素质谱仪对青藏高原东北部高寒草甸生态系统中的两种高等植物—火绒草和蒲公英的烷烃进行分析，讨论环境因素对植物单体烷烃碳同位素组成（δ13Cia）的影响。

During telophase nuclear envelopes begin to form around

在分裂后期，两个姊妹单体分离，分别拽向细胞两极。

Telophase The final stage in mitosis and meiosis, in which the separated chromatids or homologous chromosomes of bivalents collect at the poles of the spindle and the nuclei of the daughter cells are formed.

细胞分裂的末期：是细胞的有丝分裂和减数分裂的终极阶段。在这个时期内，分离的姐妹染色单体或二价体的同源染色体向纺锤体两极聚拢，同时子代细胞核形成。

The next phase is telophase , followed again by cytokinesis.

着丝粒最终分离，每个姊妹染色单体分向两极。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
