摘要
本文在庞小峰改进后的Ｙｏｍｏｓａ模型基础上，引进了激光与ＤＮＡ分子系统作用的非线性方程。并分析了方程的稳定性问题，讨论系统演变过程中，对初始条件敏感性问题。说明了ＤＮＡ分子在激光作用下，演变随机不确定性原因，除了随机因素起作用外，同时也由ＤＮＡ分子本身的非线性特性所决定。并由此解释了激光育种中的一些情况。
The nonlinear equation of laser-DNA interaction is obtained,which is based on the improved Yomosa model by Peng-Xiaofeng. In this paper, the stability of the equation is analysed and solution of the equation is sensitive to the initiative condition with system developing as time. It is shown that stochastic uncertainty, include Laser-DNA except outside stochastic factor, system itself nonlinear characteristic induces the Laser-DNA system variabled under Laser action, by means of, some difficult problems of Laser breeding are enplained.
