The experimental results show that 1,2-Octanediol has inhibitory effect on gibbsite precipitation by adsorption on the surface of seeds.

研究1，2-辛二醇对铝酸钠溶液种分过程的影响。

When the concentration of 1,2-Octanediol in the solution is less than 1.25 mmol/L, the inhibitory effect on gibbsite precipitation is limited.

添加浓度小于1.25 mmol/L时，1，2-辛二醇对铝酸钠溶液的抑制程度很小；添加浓度超过1.5 mmol/L，抑制作用非常明显。

According to experiment, polyvinyl alcohol , 12 alkyl benzene sulphur sour sodium,, single glyceride these good flaky aluminium single auxiliary of powder very too.

根据实验，聚乙烯醇、十二烷基苯磺酸钠、单甘油酯这几种也是很好的片状铝粉的单一助剂。

Other Ingredients: Sodium Starch Glycolate, Polyvinylpyrrolidone, Copolyvidone, Opadry NS Clear, Colloidal Silicon Dioxide, Sodium Lauryl Sulphate.

The results show that high content and uniform dispersed nano-alumina in composite coatings are obtained by the synergy of mined and Arabic gum.

结果表明：阴离子型表面活性剂十二烷基苯磺酸钠与阿拉伯树胶的协同作用对纳米氧化铝的分散效果最好，复合镀层中的纳米氧化铝含量较高。

She and her colleagues used the detergent SDS, which is usually used as denaturant to degrade protein, to activate hemocyanin. At certain high concentrations, instead of destroyomg the complex, it turns hemocyanin into an enzymatically active phenoloxidase.

她和她的同事用一种经常被用作蛋白质变性剂的十二烷基磺酸钠来活化血蓝蛋白，它在一定的高浓度下，增强血蓝蛋白酚氧化酶的活性而不会破坏血蓝蛋白复合物。

The experiments revealed that sodium humate has little effect on the relation between the slurry neutralizing value and the pH value, and the relation between Z and pH value is almost a straight line.

实验得出添加腐殖酸钠对料浆中和度与其PH 值之间关系的影响很小，料浆中和度Z 与PH 值之间近似直线关系，用最小二乘法进行线性拟合，可得关系式： Z =
