Along with people ask for physics function for example the timber strength etc. and the research in biomineralization increasingly thorough, it is very necessary to study the timber distribute characteristics and the dynamics characteristics in the biominerals, with the research to distribute characteristics provide basis for the material emulation of wood inorganic composites. This report simulate the distribute characteristics of Eucalyptus citriodora and Acronychia pedunculata, appearance, category, and cant on the to the dynamics characteristicThe analysis of the SEM- EDAX indicates: There are regular shape crystal combines with calcium in the Eucalyptus citriodora. its main composition is calcium carbonate. There are vegetables shape silicon stone its main composition is water and oxidize silicon. The cell wall is mainly combine part of two kinds of mineral materialses, and close combine with pass the certain chemistry key.Analyze the samples with the XPS. compute an opposite content of calcium and silicon chemical element according to peak area. The study indicates: it is a good means to analyze mineral material distribute characteristics with XPS. It is convenient for sample and its operation is simple The calcium distribution decreases with the high increment but it increase f among them, there is a maximum at the inside for Eucalyptus citriodora calcium。It decrease with high but it is increase from outside to insideThe analysis with the SAS covariance analysis software indicates: the path absorbs the emulation enunciation of the dynamics toward the mineral quality stalk absorbs the dynamics to match toward calcium polynomial mathematics model two timesThe calcium chemical element in Eucalyptus citriodora matches toward the absorption dynamics polynomial mathematics model three times. ide to inside. Press the dynamics theories to distribute the characteristics to the above mineral quality hermeneutic is: The tree trunk mainly rises the conveyance of the nourishment composition to transfer the function, along with the press of environment inside the high increment timber strong more big, and·heading up to lose to carry the nutrient is also more strong that the demand overcomes the gravity to make, the conveyance of the tree trunk delivers the function to die down, the position is more the eminence more weak to the backlog of the mineral material, and department of root for solicon of backlog function also strengthens immediately.
