Effect of a direct magnetic field on the interfacial microstructure between molten alurninium and solid iron was studied. The intermetallic phases formed in the
The improved RSA signature scheme can be strictly proved to be equivalent to the factoring problem. In the improved RSA signature scheme, when the public expone
Difference of offset spinning with conventional symmetric spinning is analyzed. A 3D FEM model for offset tube neck-spinning is established and the spinning pro
