正平截頭體-
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序列的堿基分佈為半徑是1 / 4球分佈的基礎上，用平面投影圖的方法研究和分析了6000組人類dna序列的數據，並且根據塞爾賓斯基鋪墊的補形和面心立方的布里淵區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） 。 -
Through the study and analysis conclude as follows : in human dna sequences, if the distinction of the number of the four bases is very small, they can distribute in a sphere whose radius equal to 1 / 4 ; if the distinction of them is comparative large, they can distribute between the sphere and the frustum - octahedron ; if one is 0 in them, they can distribute between the frustum - octahedron and regular - octahedron ; if the distinction of them is especial large, they may distribute in the outer of the regular - octahedron
通過研究和分析得到結論為：在人類dna序列中，如果四個堿基的數目相差很小時，它們可能分佈在半徑為1 / 4的球內；如果相差比較大時，它們可能分佈在這個球和截角八面體之間；如果在四個堿基數目中有一個為零時，那麼它們有可能分佈在截角八面體和正八面體之間；如果相差的特別大，甚至有可能落在那個正八面體的外部。
