Study on thermostable and salt-tolerant water-soluble polymers with super- high molecular weightChemical degradation of HPAM in aqueous solution and its influence factors werestudied. The oxidative degradation mechanism, including auto-oxidation and chainscission two processes, having longer kinetic chain length was established. Notably, inthe presence of the reductive impurities the oxidative degradation of HPAM inaqueous solution is remarkably accelerated.

2：线性超高分子量耐温抗盐水溶性聚合物的研究研究了部分水解聚丙烯酰胺水溶液中的化学降解作用及其影响因素，确立了它的氧化降解机制，包括自动氧化过程和链式裂解过程，具有较大的动力学链长，当有还原性杂质存在时，降解反应显著加速。

The results showed that the use of tourmaline could increase alcoholic fermentation speed of molasses, the fermentation speed kept increasing with the increase of the use level of tourmaline, however, as its use level was above 11 %, the increase of fermentation speed was inevident; the use of tourmaline had no side-effects on the content of the main impurities including methanol, n-propyl alcohol, isobutyl alcohol, isoamyl alcohol; though it had weight loss after a period of use, it could still promote alcoholic fermentation of molasses.

结果表明，电气石对提高酵母酒精的发酵速率有促进作用，随着使用量的增加，发酵速率也随着提高，当使用量超过11 %时，发酵速率的继续提高不明显；电气石对发酵过程主要杂质甲醇、正丙醇、异丁醇、异戊醇等没有影响；电气石在使用一段时间后，重量减轻，但仍有促进发酵的作用。
