vi.加积(淤高)
Second problem, owing to the suspend and colloid materials aggrading on the surface of particle electrcde, effective electrode area becomes smaller and smaller, so current efficiency falls. 其次由于原水中大量悬浮物质、胶体物质或反应中形成的絮体在粒子电极表面的聚集，导致粒子电极表面被污染，从而使有效电极面积不断降低，电流效率也随之降低。
fluvial erosion and aggrading action 河流侵淤作用
98. Aggrading streams heavily charged with bed load may fill their channels nearly to the top of the banks. 带有大量推移质的堆积河流可以把河槽淤高到几乎与岸顶齐平。
