Introduction Spinel is one of the most promising materials for use in lithium ion specific selectivity and memory because of its low cost and acceptable environmental characteristics.
The appearance of ion memory inorganic materials (ion sieve) became possible direct extracting lithium from the salt water resources[1-2].

Damping model of viscoelastic materials Although some damping models suggested by several scholars [5,6,7]after Rayleigh firstly introduced the famous theory so called ’visco damping’, represent of damping models is still more difficult for continuous system, appropriate approach contributes to a good goal.
Ideal damping model of viscoelastic material is assumed as (1) where is the damping force in a SDOF system, c is viscous damping constant.
