specific dispersion
1.The external wall thermal insulation series dispersion products prepared by BASF Functional Polymers division involve latest developed dispersion of base coat and bonding mortar specific for the exterior insulation finishing system, and the dispersion for external wall decoration system (such as the Exterior coating specific for the base plane to process putty, primer and coating decorative surface) as well as ceramic tile adhesive specific for decorative surface of ceramic tile.
2.In virtue of phonons dispersion relation, we discuss the specific heat of ( n×n)GaAs/AlAs superlattice at different temperatures.
3.And the BOA-type optical switch utilizes maximum modal dispersion (A P ), does not require a specific fabrication length or length range to operate, has simple structure, and can exhibit very high extinction-ration from its two output ports; So it is suitable for a 2 X 2 unit of optical switch array.
