HRTEM images of TDCs. (a) Sample ZJ01 of schistose structure coal, in the lattice image; BSU is dispersive and isolated, its diameter is smaller, and BSU has weak orientation, Zhangji Coal Mine, Huainan Coalfield; (b) Sample ZJ01 of schistose structure coal, (002) the (inner ring) diffraction ring lightness is stronger, (101) outer ring looms, Zhangji Coal Mine, Huainan Coalfield; (c) Sample HZ07 of mylonitic structure coal, in the image; BSU is striation group shape, its diameter is large, and BSU has stronger orientation, HRTEM, Haizi Coal Mine, Huaibei Coalfield; (d) Sample HZ07 of mylonitic structure coal, (002) diffraction ring lightness is dispersive, (101) can be seen clearly, and symmetry light spot appears, HRTEM, Haizi Coal Mine, Huaibei Coalfield.
