It was observed that rare earth ions (Nd^3+,Sm^3+,Eu^3+,Gd^3+,Tb^3+)have significant quenching effects on the fluorescence of anticoagulation factor I(ACFI),The
The viscosities of liquid Fe-4.30C and Fe-4.30C-Ce alloys were measured by oscillating crucible viscometer. The results show that viscosity of Fe-4.30C alloy ch
