The interface effects play important roles for the properties of strange quark matter ( SQM ) and the related physical processes .
We show several examples on the implications of interface effects for both stable and unstable SQM .
Based on an equivparticle model and adopting mean-field approximation ( MFA ) , the surface tension and curvature term of SQM can be obtained , which are increasing monotonically with the density of SQM at zero external pressure .
For a parameter set constrained according to the 2 M _ { \odot } strange star , we find the surface tension is \sim 2.4 MeV/fm ^ { 2 } , while it is larger for other cases .
