This paper analyzes the factors that influence the foam stability by testing the foam entrainment capability, the dynamic surface tension, the viscoelasticity, the half life period, and the foaming capacity.

A linear oscillator with visco-elastic term under narrow-band excitations was investigated by Ariaratnam~[1], Cai, Lin and Xu~[2], using an improved stochastic averaging procedu.

Experiment study on viscoelasticity of associative polymer solution under simulated reservoir conditions;

Study of viscoelasticity-anelasticity transition in the Zn-Al eutectoid alloy by measuring the internal friction;

Some damping proprieties of the fractional calculus model for viscoelastic materials;

Flow performance of viscoelastic polymer solution in dead end of reservoir pores;

The tranisition from a lamellar phase formed from a nonionic surfactant mixture system LA070/C8H17OH/H2O to a viscoelastic vesicle-phase occured by adding a little amount of ionic surfactant due to the formation of the charged bilayers which led to the change of the curvature of the bilayers.

Also did the viscoelastic properties test on them.
