Parameter region for existence of solitons in generalized kdv equation 方程孤子解的存在参数区
The results show that the nonlinear instability of system can appear in certain parameter region 表明了在一定的条件下,系统将出现非线性不稳定,这构成了论文的第二章。
The results obtained by the dissertation show that there exist the chaotic motions in some parameter regions . the research contents and the major results obtained in this dissertation are as follows 本文研究了倒立摆系统的非线性动力学,表明倒立摆系统在某些参数区域内可以出现分叉和混沌运动。
By using qualitative theory of ordinary differential equations , we have analyzed the equilibrium points , obtained the parameter region of the existence , uniqueness and nonexistence of limit cycle of the above system 应用常微分方程定性理论,对该系统的平衡点进行分析,得到了极限环存在唯一性及不存在的参数范围。
The results demonstrate that the tilted phase affects not only the relative shift and the transition height rather than the turning point , but also affects the truncation parameter region when the focal switch appears 研究结果表明,相位倾斜影响了相对焦移量、相对跃变量和焦开关发生的位置,同时也影响焦开关出现时截断参数的取值范围。
