不同变质程度煤的高分辨率透射电镜分析
High resolution TEM image analysis of coals with different metamorphic degrees
摘要
Abstract
The stur ctural characteristics of 3 coals with different metamorphic degrees were analyzed using ih gh-resolution transmission electron microscpo y ( HRTEM ) . Applying FFT-IF T method, in association with M atlab, Arcgis and AutoCAD softwares, the lattice fringe parametre s obtained from HRTEM imga e were determined using image analysis.The results indicate that the lattice fringes of all the test coal samples exhibit d ifferen t characteristics.These lattice fringes can be divided into 8 types (1×1-8×8 aromatic frineg s) according to the frni ge length distribution.Taking the 3 ×3 aromatic fringe as critical point, the sampel ML-8 abundant in 1 ×1 and2 ×2 aromatic fringes while short of 3 ×3-8 ×8 aromatic fringes whe n com paring with sampleD P-4 na d sample XM-3.The values of d002 obtained from both HRTEM and XRD show a decreasni g trend wiht increasing vitrinite refel ctance.关键词
