The utility model discloses a kind of mesh cleaning cloth, the utility model includes edge covering part and the grid part in the inside of edge covering part, the grid part includes connecting cloth, the opposite side of the connecting cloth is evenly arranged and is opened with several hexagonal mesh, the outer surface of the edge covering part is provided with micro magnetic adsorption strip, the micro magnetic adsorption strip is used for cleaning cloth to adsorb metal scrap in cleaning process.The utility model's edge covering part uses zoning design, and the four corner parts of edge covering part are provided with thickening area, effectively improve the wear resistance of cleaning cloth edge in high-strength wiping process, prolong the service life of cleaning cloth, overcome the defect that traditional cleaning cloth edge is easy to wear.The outer surface of edge covering part is provided with micro magnetic adsorption strip, the micro magnetic adsorption strip can effectively adsorb metal scrap or small iron powder in cleaning process, especially suitable for kitchen countertop, cooking plate or the area containing metal particles in industrial environment, significantly improve the functionality and cleaning effect of cleaning cloth.

The application provides a seismic profile noise removing method and device based on Kirchhoff reverse migration, which comprises the following steps: picking up noise events on a pre-stack time migration profile manually according to a given migration velocity; generating corresponding shot record of the picked noise events by using Kirchhoff integral reverse migration processing; mapping the generated shot record to source shot record, removing noise events based on FK transformation; converting the shot record after removing noise events back to the pre-stack time migration profile by using Kirchhoff integral forward migration processing. The seismic profile noise removing method provided by the application can remove noise events from the pre-stack time migration profile quickly and effectively without damaging effective information in the profile and avoiding forming local blank zone on the profile, thus ensuring the imaging quality of the seismic profile.
