dust concentration distribution on the electric field section in ESP is not uniform, this is one of reasons to produce secondary blowing dust.───电除尘器内电场断面烟尘浓度呈非均匀性分布，它是产生振打二次扬尘的重要原因之一。
solubility of gypsum will change as the concentration of acid solution changes. When acidizing treatment gypsum-containing formation, the secondary precipitation be produced.───由于石膏在酸液中的溶解度随酸液浓度而改变，酸化含石膏地层时将产生二次沉淀，严重影响酸化效果。
Appropriately, a higher concentration of the secondary pollutant is stably held for a longer downwind distance.───相应地，一个较高的次生污染物浓度将稳定地维持在一个较长的下风距离上。
