本文讨论垂直的中和浮力系留素在浮体的纵向激励处于谐振的情形下的共振响应问题，其中应力应变关系为非线性的。

In the present paper, the resonant response of a vertical mooring-line in case of neutrally buoyancy, for a given harmonic longitudinal excitation, is discussed. The law of stress-strain is nonlinear.

建立了一个反映纵向脉冲放电激励铜蒸气激光动力学过程的自洽物理模型并进行了数值求解。

A self_consistent physical model describing the kinetic process of the longitudinal pulsed discharge_excited copper vapor laser was established, and numerical solutions of the model were obtained.
