英语翻译
While such filters are macroscopically electrostatically neutral,microscopically there are charges of either sign balanced within the nonwoven structure which generate electrostatic fields strong enough to capture even uncharged particles.
这种滤材肉眼目测不带静电,在显微镜下观测,其纤维结构内部呈正负电荷平衡迹象,这样可以产生强大的静电场,甚至足以捕获到非带电粒子.
