It is proved by fractal theory that the welded state of every micro zone at welded surface is uneven in the formation process of isothermal superplastic solid-state welding joint.
这也从分形理论的角度证明了在超塑性固相焊接头的形成过程中，焊接面各微区的焊合状态是非均匀性的。

The emulsification of single emulsifier, physical mixed emulsifier and phospholipids membrane emulsifier were evaluated by the method of surface (interfacial) tension isothermal curve comparison.
The results indicated that surface excess concentration was linear to solution concentration at low concentrations linear isothermal adsorption equation was given.
