Polyester, polypropylene, high density vinylon filter cloth is widely used in the pharmaceutical, chemicals, dyes, smelting, cement, mining and other enterprises in production.

涤纶、丙纶、维纶等高密度过滤布则广泛应用于制药、化工、染料、冶炼、水泥、矿山等企业生产中。

The filter media further includes a dielectric material layer having a relative high density and a subsequent dielectric material layer having a relative lower density.

该过滤介质还可以包括密度相对较高的介电材料层及随后的密度相对较低的介电材料层。

By means of residual impulse noise detection, the window size of median filter was chosen adaptively to remove the high density impulse noise while preserving the details of the image.

通过对剩余脉冲的检测，自适应地改变滤波器窗口尺寸，从而有效地滤除密度较大的脉冲干扰，同时较好地保留图像的细节。
