本文对ＤＮＡ分子势场用辏力场近似，建立了该近似下的Ｆｏｋｋｅｒ—Ｐｌａｎｃｋ方程，并用数值法求解了本征值。发现处于生物体内的ＤＮＡ分子，由于受随机力噪声作用，影响了能级分立状态，使共振吸收频率拓宽，从而使激光育种中使用有效激光频率范围较广
In this paper, we use the force field approximation of DNA molecular potentials to establish the Fokker-Planck equation for this approximation and solve the eigenvalues numerically. It is found that the DNA molecules in the living body are affected by the random noise and affect the energy level discrete state and broaden the resonance absorption frequency so that the effective laser frequency range used in laser breeding is wider
