The paper presents the relative magnetic permeabi lity and the calculation model of por ous metal foams First, the porosity of porous foam metal is tested and obtained by the fusible paraffin; the magnetic permeability of three kinds of porous metal foam, that is, Fe, Cu, with the same structure param eters and different relative permeability are tested by vibrating sample magnetometer (VSM). Based on the equivalent reluctivity, the initial relative permeability of the electrodeposited metals is simulated and the calculated results are close to the testing results. The results show that the calculation model can be used to describe the relative permeability of electrodeposited metals, at the same time, according to the calculation, the relative permeability of porous metal foam s will increase with the in creased relative permeability of electrodeposited metals, and decrease with the increased porosity, which provide the theorical and experimental proof for the research on magnetic characteristics of porous metal foams..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
