用擴張變換法測量金屬斷裂表面的分形維數
Measurement of Fractal Dimensions on Fracture Surface by Dilation
-
摘要: 采用數學形態學中擴張變換的方法,對金屬斷口剖面跡線的分形維數進行了測量,并將結果與截島法進行了比較。Abstract: Dilating operation of mathematical morphology was taken to measure the fractal dimensions of metallic fracture profile. Comparison between the results got from dilation and slit island analysis was made.
