【 摘 要 】

A new three-dimensional cellular system based on the elongated octahedron model [1] is analyzed and discussed mathematically for its compressibility properties. It is shown that there exists negative linear and area compressibility for some certain conformations in this model. In addition, when compared with the octahedral structure, it can be found that this structure has better negative compression effect in the horizontal direction.
