中文摘要：
以双稳系统为研究对象，探讨了影响和产生双稳随机共振的参数选择特性．双稳系统参数和二次采样频率参数有着内在的物理联系，它们的改变都会引起势垒、势阱间距和粒子跃迁速率的改变，并使噪声能量相对重新分配，进而影响随机共振效果．根据随机共振的参数选择规律，可通过适当的参数选择来得到最佳的随机共振状态，为后续数据处理奠定基础．
英文摘要：
Taking a bistable system as a research object, the strategy of choosing parameters for affecting and producing stochastic resonance （SR） is investigated. The system parameters of the bistable system and the frequency parameter of twice sampling are related to each other intrinsically. Their variation can cause changes in the height of the potential barrier, the distance of the potential wells and the transition speed of the particle, causing redistribution of the relative noise energy and leading to different stochastic resonance effects. According to the regularity of the parameter choice for the stochastic resonance, the optimal stochastic resonance can be obtained by choosing these parameters properly, which lays the foundation for further data processing.
