In this paper , we study and analysis the base distribution in human dna sequences . on the basis of the distribution sphere whose radius equal to 1 / 4 by zhang et al . expounded , with the method of plane mapping figure studying 6000 human dna sequences , and according to the figure of sierpinski gasket ' s patch and the brillouin zones of the face - centered cube , we obtain two new distribution figures , one is the frustum - octahedron , another is the regular - octahedron 我們在zhangetal .提出的人類dna序列的堿基分布為半徑是1 / 4球分布的基礎(chǔ)上,用平面投影圖的方法研究和分析了6000組人類dna序列的數(shù)據(jù),并且根據(jù)塞爾賓斯基鋪墊的補形和面心立方的布里淵區(qū)圖形提出了兩種新的分布圖,一種是正八面體,另一種是截角八面體(十四面體) 。
