After discussing the major factors affecting model-based creep experiment and the rules to dispose in designing experimental model,the needed similarity relationship for constructing models is presented,then the similarity relationship of cambers due to creep between model and original is put forward based on creep expression in CEB-FIP Model Code 1990.

Current similarity based approximate reasoning methods (SBARs) have various views on similarity relations and neglect the effect of dissimilarity relations.

Beholavek studied the similarity relations between two fuzzy concept lattices L(U,A,I_1) and L(U,A,I_2).

In this paper, we studied the P3 approximation diffuse reflectance of different phase functions based on the similarity relations, and analyzed the influence of HG, Tissue and HG-HG phase functio.
