NOBS PAG , can obviously activate hydrogen peroxide thus , the efficiency of hydrogen peroxide bleaching can be advanced greatly .

研究结果初步表明，此类有机酰化剂类如：四乙酰乙二胺，四乙酰甘脲，异壬酰氧基苯磺酸钠，五乙酰葡萄糖等有着非常明显的活化过氧化氢的作用，从而能在很大程度上提高纸浆过氧化氢漂白的效率。

It was found experimentally that HIC happens via nonacid nucleation and then quasi-cleavage along {111} planes when C〓 is higher. Otherwise, in the case of lower C〓, hydrogen enhances ductile fracture via hydrogen-enhancing microvoid nucleation, growth and connection.

对预充氢的310钢薄膜进行TEM原位拉伸表明，当氢浓度较高时，氢致断裂通过空洞形核，然后沿{111}面准解理扩展的方式进行；当氢浓度较低时，氢促进纳米空洞形核、长大和连通，进而导致韧断。
