摘要: 本文研究了生物大分子如DNA在ATP水解作用或其它刺激作用下所产生的局域性涨落和结构畸变（如碱基对的相对运动等）所诱导的孤立子激发的特性，以及这种激发与生物大分子的生物能（如DNA的复制等）之间的关系和它的分形、分维特性。

Abstract: Properties of the solitonic excitations generated by the localized fluctuation and the structure deformation due to ATP hydrolysis and other excitation in DNA were discussed by using a new Hamiltonian function. A solitonic motion model in DNA was established. Some elementary biological functions such as the duplication, the transcription and the inheritance of DNA, as well as its fractal feature could be elucidated with this new solitonic model.
