Constructing dependable services with fault tolerance abilities will be a feasible strategy,which is to choose the candidate component with behavioral consistency to dynamically replace the error component based on service component interface models.

Aimed at the existing problems of the localization mechamism of JXTA network resources,an algorithm thought was proposed based on the combinaiton of small world theory with interest attenuation mechanism in rumor spreading;by using the strategy of dynamic replacement of long chain,the problem of blind searching,which exists in the JXTA resources discovery,was improved.

The parameters in the steric-mass action (SMA) model for the novel displacers and their displacement performance were determined by chromatographic experiments, adsorption equilibrium and batch displacement experiments, and were compared with.
