Thermodynamics formulation of different coupling conditions between damage and plasticity

Analysis of The Spatial Coupling of Natural Resource And Economy in Small Upland Drainage Area ——Taking Small Upland Drainage Area of Anji Country of Chekiang Province as Object The spatial coupling of natural resource and economy was studied in small upland drainage area of Anji country.

This research aims at the performance of this method in coupled rooms,and proposes an improved model based on acoustical radiosity,to predict the sound decays in a system of two coupled rooms.

The finite element method is used to study the normal modes distribution in coupled rooms.

Study of space coupling technology of fiber bundle coupling LD output beams;

For study the optical field distribution of multi-mode fiber coupling LD output beam through space coupling optical system,the optical field distribution of output end of multi-mode fiber are analyzed,the transmitted properties of multimode beams passing through optical system are discussed based optical ABCD matrix,and the distribution parameter of coupled beam are measured experimentally.
