| Abstract: | This paper reports a new way by which three-dimensional images of coal ball plants are revealed conveniently. In order to reconstruct outer images of coal ball plants, especially seeds, three different reconstruction methods (additional method, symmetric method and mixed method) have been developed. In the meantime, the way of reconstruction of membrane-like structure was explored. The establishment of these methods contributes to the reconstructing the whole shape of coal ball plants and relating coal bails to other fossil forms. In addition, the difficulties in three-dimensional reconstruction of coal ball plants by using computer are discussed. |
