重聚合

The structure of the composite was characterized and analyzed by XRD, FTIR and TG. The test results proved that the structure of bentonite did not change except that the interlamellar spacing increased a little during its aggregation. The dispersion property and thermal stability of the composites was enhanced thereby.

使用X射线衍射、红外和热重对复合材料的结构进行了表征和分析，结果表明，膨润土在聚合过程中除了层间距有所增大外，基本结构不变，而且分散度提高；吸水性复合材料的热稳定性提高。

Synthesized polymerizable photosensitive monomer diazo naphthoquinone sulfonate hydroxyethyl methacrylate ether was characterized by infrared spectroscopy and 1H NMR.

田丰，于媛媛，汪长春*摘要：利用红外光谱和核磁共振(1H NMR)对所制备的光敏可聚合单体重氮萘醌苯磺酸甲基丙烯酸羟乙酯进行了表征。

In contrast, exposure to ectopically expressed noncanonical Wnt11 markedly decreased the expression of Oct-4 and Nanog and induced mRNA expression (quantitative real-time reverse-transcription polymerase chain reaction) of cardiac-specific genes (Nkx2.5, GATA-4, atrial natriuretic peptide,- and -myosin heavy chain, and cardiac troponin T) by day 3 with subsequent progression to a pattern characteristic of the cardiac fetal gene program.

对比之下，接触到非典型wnt11能明显降低Oct-4 和 Nanog表达和在第3天出现诱导心脏特异性基因（Nkx2.5，GATA - 4，心房利钠肽，- and -肌球蛋白重链，肌钙蛋白T）mRNA的表达（应用反转录聚合酶链式反应实时定量），随后逐渐表达为心脏胎儿基因。

The key factors affecting the polymer intrinsic viscosity were found to be monomer recrystallization times,stannous octoate concentration and polymerization time.

单体重结晶次数、辛酸亚锡浓度、聚合时间等条件均是影响聚合物特性粘数的重要因素。

Microwave-assisted ring-opening polymerizations of DTC were carried successfully with lanthanum chloride (LaCl3) and stannous octoate Sn(Oct2 ascatalyst and the highest weight average molar mass of the obtained PDTC were 66800g/mol and 14600g/mol, respectively.

分别在氯化镧和异辛酸亚锡的催化下，DTC的微波开环聚合反应可以顺利地进行，所得PDTC的重均分子量分别达到66800g／mol和14600g／mol，二者比较而言，氯化镧的催化活性更高。

Using six-color flow cytometry (with antibodies CD45, CD19, CD5, CD10, kappa, and lambda) and immunoglobulin heavy-chain gene rearrangement by reverse-transcriptase-polymerase-chain-reaction assay, we determined the association between MBL and subsequent CLL and characterized the immunoglobulin gene repertoire of the prediagnostic B-cell clones.

使用六色流式细胞术（使用CD45、CD19、CD5、CD10抗体、Ig κ和Igλ）和逆转录聚合酶链反应试验的免疫球蛋白重链基因重排，我们确定了MBL和随后的CLL之间的关系，明确了诊断前B细胞克隆的免疫球蛋白基因库。

Therefore, the disruption of the actin cytoskeleton initiates a cascade of structural and functional alteration in renal epithelial cells and which will lead to the dysfunction of reabsorption in kidney.

肌动蛋白聚合形成了肾脏上皮细胞内对微绒毛起支撑作用的细胞骨架，因此肌动蛋白细胞骨架的破坏势必导致肾小管上皮细胞结构和功能的改变，从而引起肾脏的重吸收功能障碍。

Compared with other flocculants, the polymeric ferric sulfate has much better performance and characteristics, such as better adsorption, bridge erection, flocculation, floc formate fast, not easy to breaking, better repolymerization and weak corrosion. So it was widely used in the wastewater purification and treatment which contains industrial wastewater, urban sewage, water for industrial use and potable water etc.

与其它的絮凝剂相比较，聚合硫酸铁不但具有较强的吸附、架桥、絮凝沉淀性能，而且在水处理过程中有生成絮体速度快、絮体不易破碎、重聚性能好、腐蚀性小等特点，因此广泛用于工业废水、城市污水、工业用水以及生活饮用水等的净化处理。

Results The two patients with primary dystonia were found to have the gene mutation of SCA3,the CAG repeat were 80 and 75 respectively.
