coal scatter
1.After the classic structural model of coal had been reviewed,the new conceptofmulti element amorphous structure of coal was put forward The radial distribution ofatomsin coals was studied by X ray diffraction The results have shown that there are aro maticcarbon atom layers and alicyclic carbon atom layers in the macromolecules of coal,andboththe aromatic layers and alicyclic layer scatter coherently X ray,and that the order ofamorphouscoal structure is less than 1 nm The model and variation of amorphous coalstructurewere discussed in this paper
