vi.加積(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懸浮物質、膠體物質或反應中形成的絮體在粒子電極表面的聚集，導致粒子電極表面被污染，從而使有效電極面積不斷降低，電流效率也隨之降低。

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. 帶有大量推移質的堆積河流可以把河槽淤高到幾乎與岸頂齊平。
