Taking the thermodynamics potential for cold dense QCD in perturbation theory to the first order in coupling constant account, we calculate the bulk viscosity of strange quark matter(SQM), and find that the result is approximately 10 2 times than that of the ideal quark gas.

Taking medium effects into account, we calculate the bulk viscosity of strange quark matter in high temperature approximation using a consistent thermodynamics method in quasi particle description.

Research on measurement method for viscosity coefficient of liquid;

A method of using Brillouin scattering technique for measuring directly the bulk viscosity of water is proposed.

Temperature effect to waste liquid coefficient of viscosity and foam safety during potato process;

Methods: The computer programme of counting liquid coefficient of viscosity in realizing unlimited extensive situation was designed.

Due to the stress, the thick ness of bond water changed, then does the coefficient of viscosity.

Nucleoplasmic Viscosity of Living Cells Investigated by Fluorescence Correlation Spectroscopy

On the basis of the results of viscosity measurements of binary solutions of surfactant and oil,we can know weather micelle structures have been organized and,furthermore which oil can be emulsified by surfactant and water to become emulsion or microemulsion solution.

To the problems existing in the experiment of viscosity coefficient, some improvements on measurement method for the velocity of sphere are given.
