The density of molten Ni-W alloys was measured with a modified pycnometric method. It is found that the density of the molten Ni- W alloys decreases with temper
Nation modified Pt nano-particles with size about 4nm were synthesized. The modified particles were absorbed on the surface of carbon nanotubes and used as elec
The factors influencing mechanical performances of viscoelastic material are studied. The properfinite element model for dynamical calculating the passive contr
