【摘要】 报道了一个带耗散性元件和过电压保护的张弛振荡电路模型,它由一个保守映象和一个耗散映象不可逆耦合而成的分段光滑映象描述。在这样一个半耗散系统中,我们的数值计算表明在一定参数范围内,系统的动力学行为完全由类耗散性支配,并且发现了"类激变",所得结果与实验一致,这是首次在半耗散系统中发现类激变。更多还原

【Abstract】 The thesis reports a relaxation and oscillation circuit with over-voltage protection and a dissipative unit,which is described by a piecewise-continuous concatenation of a dissipative map and a conservative map.In such a semidissipative system,our numerical calculation shows that dynamics behavior of the system is completely dominated by quasi-dissipation,we find quasi-crisis which is first found in a semi-dissipative system,and the results are agreement with the experiment更多还原
