| 摘 要： | 将DNA分子看成一维二元随机序列，利用负本征值理论计算其态密度，针对碱基对分布和相对含量等参量，讨论了DNA分子的电子结构.结果表明碱基对分布和相对含量都对电子能态结构影响较大，说明碱基序列对DNA分子的电子结构影响很大.

| Abstract: | The DNA molecule is considered as one-dimensional disordered binary system. Its electronic structure is discussed in terms of base pairs′ relative percentage and distribution using the density of electronic states which are calculated by the negative eigenvalue theory. The result shows that the effect of the base pairs′ relative percentage and distribution on the electronic energy state structure is great. In other words, the sequence of the base pairs plays an important role in determining the electronic structure. |
