The possibility of the existence of solitary waves in DNA is investigated. On the basis of our classical model we do not find such a wave in a polynucleotide, but for a stack of adenine molecules without backbone we observe one. Possible extensions of the model for DNA are discussed. From our results we can conclude, that solitons exist in stacked systems without an additional backbone. At least the degree of freedom which couples a nucleotide base (pair) to the sugar-phosphate backbones (N-C stretching vibration) has to be treated with the help of the quantum equations of motion.
研究了DNA中孤波存在的可能性。基于我们的经典模型，在多核苷酸中未发现此类波，但对于没有主链的腺嘌呤分子堆叠，我们观察到了一个孤波。讨论了DNA模型可能的扩展。从我们的结果可以得出结论，在没有额外主链的堆叠系统中存在孤子。至少将核苷酸碱基（对）与糖 - 磷酸主链耦合的自由度（N - C伸缩振动）必须借助量子运动方程来处理。
