Based on the properties of the threshold movement of bottom mud due to progressive wave, a theoretical solution of bottom shear stress due to progressive wave action was derived, assuming the water as viscous fluid and the mud as visco-elastic medium.

The bottom shear stress and sediment movement for a wave-current coexisting system;

Based on the theory of boundary layer, a shear stress has been derived;the carring capacity for wave-current system has been introduced by means of the energy theory and a series of coefficients are given as well.

A theoritical bottom shear stress for a wave-current coexisting system is derived by means of the theory of boundary layer assumption.

Influence Coefficient Method for Computing Interfacial Shear Stresses of Film-to-Substrate;

Debonding interfacial shear stress near crack of RC beam strengthened with CFRP

With the experiments of 16 RC beam strengthened with CFRP,the paper mainly studies the interfacial shear stress distribution.

Wall shear stress method integrates the plug flow displacing,the low speed displacing and the turbulent flow displacing methods in theory.

The instantaneous wall shear stress and wall-liquid mass transfer coefficient for gas slugs rising through the liquid column in a vertical tube were measured by using limiting diffusion current technique.

According to the results, in great details the macromolecule transport influences of wall shear stress, non_Newtonian fluid character and the scale of the molecule etc are given.
