摘要 本文研究一类非线性双曲型方程的初值问题,对其整体强解的存在性与唯一性给出了证明。该问题涉及的模型方程是在刻画DNA分子横向波的传播时提出的,文中的结果给出了这个模型方程在实际环境中呈现出的具体形态。 The initial value problem for a nonlinear hyperbolic equation is studied. The existence and uniqueness of the global strong solution to the problem axe proved. The relative model equation is given to describe the propagation of longitudinal waves on molecules of DNA. The obtained conclusion describes the behavior that the model equation reflects in actual circumstances.
