分别以聚合氯化铝、聚胺、聚二甲基二烯丙基氯化铵和高取代度阳离子淀粉作为固定剂，研究了它们对废纸浆中微胶黏物的控制效果及对纸页性能的影响。

Wheares under buffer pH5.2, there is no strong static electricity and instead being a longer wavelength movement; SDS\'s participation just restricts the relative movement of heme\'s ethylene; a new fluorescent peak forms and the reduction of enzymatic activity is due to the packing of micella\'s formation.

强变性的阴离子表活剂SDS与带净正电荷和弱负电荷的SBP(处于pH2.6和4.2缓冲液中)有强烈的静电力作用，酶活力丧失，二级结构变化，荧光强度增加，特征Soret发生蓝移，卟啉环的π-π*共轭的分裂能增大；而当SBP带净负电荷(pH5.2)时，没有静电吸引力，Soret带发生红移；SDS的引入只是限制了血红素上乙烯取代基的运动，使其与卟啉环共轭：极性环境的变化导致产生新的荧光峰；酶活力因胶团包裹作用而有下降。

This paper categorizes the different kinds of sulfone antifungal research, emphasizing a review of some of the bioactivity research that has been conducted and discussing the effect on bioactivity of different substituent groups. Sulfone development trends and prospects for future application of sulfone compounds is also discussed.
