scrubbed

She scrubbed the stain on the floor.

她把地污迹擦掉了。

The mother scrubbed the floor and her child did the same.

母亲擦地, 孩子也跟着干。

She scrubbed the kitchen floor until it was clean as a whistle.

她把厨房地擦得乾乾净净。

Each frame is scrubbed four times to erase jaggies, and PGR3 still runs at 60 frames per second - twice the rate of TV.

就是PGR3在四倍全屏抗锯齿下画面一流，而且还是以60帧/秒速度运行。
