The correlativity between four physical properties,including Δd(Difference of density)、lnν(Logarithm of kinematic viscosity)、w(CCR)(Mass fraction of carbon residue)and w(S)(Mass fraction of sulfur)and SARA mass fractions of atmospheric residue and vacuum residue was respectively discussed.

The different mass concentrations of the three surfactants,sodium dodecyl sulfonate(SDS),cetyltrimethyl ammonium bromide(CTAB) and oleic acid were added into Lungu atmospheric residue(LGAR),respectively,to investigate their effects on the 80℃ kinematic viscosity,colloidal stability,contents and average relative molecular mass of SARA four fractions of LGAR.

The kinematic viscosity values of the saturated liquid dimethoxy methane are reported over the temperature range from 248.

It was concluded that the elastic modulus G′, loss modulus G″ and dynamic viscosity η~ of PLA and its copolymers increases with the increasing of the molecular weight.

The dynamic viscosity of the HEC solution increased nonlinearly with the increase of the HEC mass fraction.

Based on dissipation mechanism of shearing power,a new method of modeling dynamic viscosity of polymer melts in vibrating shear flows was proposed in this paper.

On the basis of the experiment, the factors affecting the stability namely the equivalent diameter of the nano-particles and the dynamic viscosity of the base fluid are discussed and some valuable conclusions are obtained.
