中文摘要:
      为了有效避免有害气体浓度的超标对经济效益和人类生命财产安全造成损害,提出并设计了一种新型检测方法,通过对微纳电离型传感器进行一系列的测试,设计的传感器展现了较强的抗弯能力及较快的响应-恢复能力。在室温常压、相对湿度75%的实验条件下,对多个浓度的苯、甲苯气体展开了测试,并基于特征噪声强度识别气体的浓度,构建了对应的识别模型。实验结果表明:传感器对有害气体检测时的测量值和真实值的拟合度可达99%以上,体现了较高的检测精度,且在检测有害气体时传感器处于可逆电离平衡状态,重复性良好,不需要进行预热、安全无毒,因此适合于应用到苯类气体的检测中,能够满足效率、精度的要求,具备了一定的实用性。
英文摘要:
      In order to effectively prevent the excessive concentration of harmful gases from causing damage to economic benefits and the safety of human life and property,a new detection method has been proposed and designed.Through a series of tests on micro/nano ionizing sensors,the designed sensor exhibits strong bending resistance and fast response recovery ability.Multiple concentrations of benzene and toluene gases are tested under experimental conditions of room temperature,atmospheric pressure,and relative humidity of 75%.Corresponding recognition models are constructed based on the intensity of characteristic noise to identify the concentration of the gas.The experimental results show that the fitting degree between the measured value and the true value of the sensor for detecting harmful gases can reach over 99%,reflecting high detection accuracy.Moreover,the sensor is in a reversible ionization equilibrium state when detecting harmful gases,with good repeatability and without preheating.It is safe and non-toxic.Therefore,it is suitable for application in the detection of benzene gases,meeting the requirements of efficiency and accuracy,and has certain practicality.
