Abstract: Three metamorphic processes are put forward based on the metamorphic principle of metamorphic mechanism：the member-increased, the member-decreased, and the member- unchanged but changing its configuration. After researching the three processes of metamorphic mechanism’s structure changing, the processes to describe the metamorphic mechanism’s structure changing are brought forward by using the transformation of adjacent matrix, and at the same time, 4 kinds of elementary matrixes, which are accordingly used to transform adjacent matrix are put forward. This matrix transformation can clearly describe the change of adjacent characteristic of every component and the number of increasing and decreasing components in the process of structure changing. The matrix transformation, which is used to describe the processes of metamorphic mechanism’s structure changing, can translate the structure changing of metamorphic mechanism to series of matrix operation. This method can be used in the analysis of all kinds of metamorphic mechanisms’ configuration transform- ation. The transformation is done by matrix, and doesn’t need to give numbers to the new mechanisms, so it can be easily calculated by computer.
