When strain waves pass through a ferromagnetic bar,owing to piezomagnetic effect,a nonuniform magnetic current will be stimulated by the strain wave simultaneously. 应变波通过铁磁性杆件时，由于压磁效应，会同时在杆件中激发出不均匀的磁流。
A thresholding method based on fuzzy exponential entropy and simulated annealing algorithm is proposed to segment a gridding image with nonuniform illumination efficiently. 摘要为了有效分割照度不均匀的网格图像，提出了一种基于模糊指数熵和模拟退火算法的阈值分割方法。
