20080222215	Method for Deleting Virus Program and Method to Get Back the Data Destroyed by the Virus - The present invention discloses a method of recovering data corrupted by a virus program, comprising: obtaining a devastating behavior operation step that can be performed by the virus program; establishing a reverse behavior operation step corresponding to the devastating behavior operation step; performing the corresponding reverse behavior operation step in response to the devastating behavior operation step that can be performed by the virus program. The present invention further provides a method of removing a virus program, comprising: establishing reverse behavior operation steps corresponding to operation steps of the virus program, executing the reverse behavior operation steps and removing the program to be checked. The method of the present invention employs different reverse behavior operation steps for different virus programs, recovering data corrupted by a virus program, eliminates the defect that existing methods of removing a virus perform a identical processing step for any virus program, enabling the computer removed of the virus program to recover as far as possible to its previous state before infected by the virus program.	09-11-2008
20080289042	Method for Identifying Unknown Virus and Deleting It - A method for identifying unknown virus program, includes: getting the behavior data of the program that would be tested, determining whether the said program is a virus program or not based on the behavior data of said program and the behavior data of pre-setting typical virus program. A method for deleting the virus program, according to the behavior of the virus program, sets and performs an anti-operation which is in reversed to the virus program, and gets back the destroyed data.	11-20-2008

20100031773	COMPOUND MAGNETIC POWDER AND MAGNETIC POWDER CORES, AND METHODS FOR MAKING THEM THEREOF - The present invention provides a compound powder for making magnetic powder cores, a kind of magnetic powder core, and a process for making them. Said compound powder is a mixture composing of powder A and powder B, the content of powder A is 50-96 wt. % and the content of powder B is 4-50 wt. %, wherein powder A is at least one selected from iron powder, Fe—Si powder, Fe—Si—Al powder, Fe-based nanocrystalline powder, Fe-based amorphous powder, Fe—Ni powder and Fe—Ni—Mo powder; powder B bears different requirement characteristics from powder A and is at least one selected from iron powder, Fe—Si powder, Fe—Si—Al powder, Fe-based nanocrystalline powder, Fe-based amorphous powder, Fe—Ni powder and Fe—Ni—Mo powder. Said powder B adopts Fe-based amorphous soft magnetic powder with good insulation property as insulating agent and thus core loss of magnetic powder core decreases. The decrease of magnetic permeability of magnetic powder core resulting from a traditional insulating agent is remedied and the initial magnetic permeability of magnetic powder core is improved by taking advantage of soft magnetic properties of Fe-based amorphous powder.	02-11-2010
