Rough set model based on importance degree similarity relation in incomplete information system;

Calculation method of relational similarity based on singular value decomposition

This paper further extend under determinism of incomplete decision information systems and set-pair analysis ,which is rough set extension based on set-pair connectivity similarity relation .

Similarity Relation of Model Experiment about Thermal Environment of Tunnel Inside;

Decomposition of Rough Set Based on Similarity Relation;

Set approximation and its interpretation on vagueness based on similarity relations

Further discussion on similarity relationship between stratified flow and uniform flow;

Some similarity relationships between density flow and uniform flow in open channel;

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.
