摘要

Based on maximum entropy method (MEM), the particle swarm optimization (PSO) with inertia weight factor was effectively applied for the quantitative texture analysis, and satisfying calculation results have been obtained for complete orientation distributions of many deep-drawing steel sheets and purity copper samples with macro orthogonal symmetry. In the processing data, there is not any assumption except that the entropy is maximum, furthermore, the calculated results are not affected by the sample compositions, texture compositions as well as their orientation distributions at all.
