Classification and principle of rigid waterproofer;2. The circinal cavities were found in calcium alginate beads and the cylinder holes were observed in zinc alginate beads from the SEM,which indicated that the volume of fraction of zinc alginate polymer was relatively bigger and the zinc alginate polymer chain was more rigid than that of calcium alginate .

凝胶的SEM照片可见，海藻酸钙的冷冻干燥颗粒内为较大的圆孔，海藻酸锌凝胶内为较小的长孔，表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强；卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明，由于上述海藻酸锌凝胶的特性，导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强；根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1。

From the UV spectra, it can be found that the aromaticity of acenaphthenyl groups in C_2 gum is the largest. But there are 30 carbon atoms in the conjugated structure of condensed aromatics in C_1 gum and C_3 gum, while 28 carbon atoms in acenaphthenyl groups in C_2 gum.

但是，在C_1胶、C_2胶和C_3胶三者中，C_1胶侧链上的四苯基苯基和C_3胶侧链上的菲式多苯基苯基都含有30个碳原子，而C_2胶侧链上的苊式多苯基苯基含有28个碳原子，比前面二者小2个碳原子，理应其芳香性在三者之中最小，但事实却恰恰相反。

The effect of the SDT／S on the properties of NR compound was investigated The results showed that SDT／S plays the advanced role in NR compound,in order to keep the vulcanizate properties level as before may decrease some accerlator;the physical properties of overcured vulcanizate,the adhesion strength of optimum cure or overcured valcanizate between rubber and cord were improved by adding 2 phr of SDT／S to NR compound.

研究了SDT／S对天然胶胶料配方各项性能的影响。结果表明：在配方中使用SDT／S，对天然胶胶料起硫化促进作用，为保持原水平的硫化特性，可以适当减少促进剂的用量；可有效提高胶料过硫化条件下的300%定伸应力、扯断强度、邵氏硬度、撕裂性能、磨耗性能，可有效提高正硫化或过硫化条件下的胶料与帘线间的附着力。

Results The bletilla colloid was a homogenous viscous colloid whose relative viscosity was 2324.6 mm2/s. It was easily injected through 4-F catheter and hyperattenuating under fluoroscopy, meanwhile, with good histocompatibility and hemo-compatibility, without pyrogenetic response and toxicity. In vitro, the mixture of bletilla colloid and MMC did not produce separation and suspention phenomena but released 50%of MMC at 1.8h and 100%at 3.4h. The bletilla colloid mainly embolized peripheral arteries, maintaining occlusion for 5 weeks and without formation of collateral circulation. The injuries of normal hepatic tissues were slight, without hepatic cytonecrosis.

结果 (1)白芨胶为一种均质的胶状物，有一定粘滞性，相对粘度2 324.6 mm2/s，不透X线，易经4F导管注射；(2)白芨胶具有良好的血液相容性和组织相容性，无致热原性及毒性作用；(3)白芨胶-丝裂霉素C体外混合后，无分层及悬浮现象，释放MMC 50%约需1.8小时，100%需3.4小时；(4)白芨胶主要栓塞末梢小动脉，栓塞牢靠，维持时间可达5周，不易形成侧支循环；(5)白芨胶栓塞对正常肝组织损伤轻微，未出现肝细胞坏死。

The hydrophobic monomers such as glycidyl octyl dimethylammonium chloride, glycidyl dodecyl dimethylammonium chloride, glycidyl tetradecyl dimethylammonium chloride was applied to the hydrophobic modification of two kinds of sodium cellulose sulfate in isopropyl alcohol under 65℃.The success of synthesis of a kind of novel amphoteric surfactant by FT-IR and NMR. 3. By the measuring surface tension of all kinds of amphoteric polymeric surfactants based on cellulose, the critic micelle concentration was obtained such as 0.4wt%、0.3wt%、0.25wt% and corresponding surface tension was about 30mN/m

通过动态接触角测量仪确定了各种纤维素表面活性剂的表面张力和临界胶束浓度，结果表明该类表面活性剂可与小分子表面活性剂的降低表面张力的能力相媲美，最低可达28.41 mN/m，随着疏水基中碳链的增长，降低表面张力的能力下降，而临界胶束浓度从0.4wt%相应降低0.25wt%；应用环境扫描电镜确定其不同浓度胶束形态，结果表明在较低浓度下形成棒状单分子胶束，随着浓度的升高，单分子胶束逐渐聚集成树枝状胶束，进一步提高浓度，则聚集成网状结构；此外，采用了高级流变仪对其溶液的流变性质进行了研究，结果表明其溶液属于剪切变稀流体，是高分子溶液特有的性质。
