The method was based on the inhibitory effect of oxalic acid on the oxidation of isatin by H 2O 2 enhanced by non-ionic surfactant-Triton X-100 in the HCl medium.

在稀盐酸介质中，微量草酸对H2 O2 氧化靛红的褪色反应有显著的阻抑作用，非离子表面活性剂TritonX 1 0 0对此体系有强烈的增敏作用，据此建立了表面活性剂增敏阻抑动力学光度分析测定微量草酸的新方法。

This transaction follows the acquisition of the US-based surfactants manufacturer McIntyre in February 2009 and the recent start up of our new surfactants unit in Roha.

这宗交易是按照2009年2月在美国收购的表面活性剂生产商麦金太尔和最近开始对我们单位的新表面活性剂在柔哈。

In the calculation, a surfactant molecule is divided into the hard-sphere segments, according to its molecular formula.

在计算中，将分子按照其分子式划分为硬球链节，对7个非离子表面活性剂—水体系的临界胶束浓度进行了关联，并预测了其它18个表面活性剂体系的临界胶束浓度。

The shear viscosity of interfacial films containing nonionic surfactant, polyoxyethylene(4)nonyl phenyl ether (0.04 % mass fraction) and anion surfactant, sodium oleate (0.04 % mass fraction) decreased with the increase of time, and finally inclined to a constant. But the shear viscosity of interfacial films containing montmorillonite increased with the increase of t...

结果表明非离子表面活性剂壬基酚聚氧乙烯(4)醚polyoxyethylene(4nonylphenylether、阴离子表面活性剂油酸钠在0.04%浓度下其界面剪切粘度随时间延长而逐渐降低，然后趋向恒定；而蒙脱土界面剪切粘度随时间延长而逐渐上升，然后趋向恒定。

First, the finite difference was used to solve numerically the coupled Navier-Stokes equation and the convective-diffusion equation for surfactant in a orthogonal body-fitted coordinate system. The effect of surfactant on the flow field inside and around the deformed drop was successfully simulated.

本文在正交贴体坐标系下采用有限差分方法，对不可压缩流体的Navier-Stokes方程和表面活性剂的对流—扩散方程耦合求解，从而首先模拟了表面活性剂对单液滴运动的影响。

With the same final brightness about 84%ISO, O~*P pulp consumed less active chlorine and peroxide compared with the OP pulp; although O~*P pulp needed a higher beating energy,the tensile index,tear index and burst index of the pulp were better than those of OP pulp at the same ~oSR value.

当漂白浆的白度均为84%ISO左右时，与CK2 OP漂白浆相比，CK2 O~*P(O~*为表面活性剂S3强化的氧脱木素)漂白浆所消耗的漂白化学品的量更少，即氧脱木素段添加合适的表面活性剂能有效降低漂白化学品用量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
