%X Considering the availability and derivation of Roscoe's equation for absolute viscosity calcula-tion,the method to adopt λ_0 value,so-called λ_f,was proposed by experimentally deter-mining relational curve of the measured height,H,of metal melt vs logarithmic oscillationdecrement,λ,extrapolating H into zero,if such corresponding λ value is taken.Experimentalresults show that the proposed method not only satisfies the availability of original equationbut also eliminate the effects of:“end and slippage”,so as to improve the accuracy for liquidCu and Sn examinations.
