摘 要：用Q900自动图象分析系统测定了用(NH4)2WS4热分解制备的WS2颗粒的分形结构，得到WS2周边分维数Df在1. 015~1. 032范围，表面分维数Ds在2.015~2.032范困，其分维数随着粒度减小而增大。给出了Df、 Ds与颗粒等效直径d的关系，Df、Ds可以作为WS2颗粒形状和大小的表征值。
Abstract: The fractal dimension of WS2 particles produced from (NH4)2WS4 by means of thermal decomposition was measured with the Q900 automatic image analysis system. Experimental data showed that fractal dimension Df of the outline ranged from 1.015～1.032, fractal dimension Ds of the surface ranged from 2.015～2.032, and fractal dimension increased with the decrease of particle size. The relation between Df DS and WS2 particle equivalent diameter d was given. Df ,Ds signified the characteristic of the morphology and size of WS2 particles.
