摘　　要：首先介绍了白噪声激励下随机共振的概念、模型及其基本原理,探讨了环境污染物信号检测的重要性。然后,通过仿真实验向模拟的污染物检测系统中输入0、0.1、0.25、1等不同强度的噪声,以研究白噪声激励下对环境污染物检测场景的随机共振现象。结果表明,可以引入一定参数的白噪声,通过随机共振现象可提高对污染物信号的检测质量,为环境检测技术的进一步发展提供有价值的参考。Fisrstly,the concept,models,and fundamental principles of stochastic resonance under the excitation of white noise are introduced,along with the importance of detecting environmental pollutant signals being discussed.Subsequently,through simulation experiments,various intensities of noise,such as 0,0.1,0.25,and 1,are input into a simulated pollutant detection system to study the phenomenon of stochastic resonance in the context of environmental pollutant detection.The results indicate that introducing white noise with certain parameters can enhance the quality of pollutant signal detection through stochastic resonance,providing valuable insights for the further advancement of environmental detection technology.
