负离子测试设备电荷容量衰减模型优化分析

Analysis of attenuation model for charge handling capacity for negative ion testing equipment

负离子对人体的健康有重要作用,负离子测试设备的原理在于对其放电过程进行检测,并根据数学模型判断环境内负离子数量。对基于国家标准的数学模型进行优化,并采用差异演化算法拟合。研究结果表明该模型对放电过程的拟合效果有较大的改善。

The negative ions have important effects on the human health.The operation principle of negative ion testing equipment is that the discharging process is detected,and the number of negative ion is judged according to a certain mathematical model.The mathematical model based on the national standard was built,and the differential evolution algorithm was applied in the process of fitting.The research results show that the model can improve the fitting of discharging process.
