摘要： 通过搭建电化学反应装置,研究电化学条件对氢氧化钠溶液中共晶镓铟合金（EGaIn）电阻的影响。实验结果表明,EGaIn电阻在多变量影响下（EGaIn体积、电极电压、NaOH溶液浓度和电极直径）发生非线性变化。采用广义加性模型（GAM）系统分析多变量的交互作用,以揭示各因素对电阻的非线性影响。与传统的线性回归方法相比,GAM能有效处理多个变量之间的交互效应。研究结果对于提高环境监测、能源存储、工业过程控制、智能穿戴设备等多个领域电化学传感器的效率和安全性具有现实意义。

Abstract: The influence of electrochemical conditions on the resistance of eutectic gallium indium alloy （EGaIn） in sodium hydroxide solution was studied by constructing an electrochemical reaction device. The experimental results show that the EGaIn resistance changes nonlinearly under multivariable influence （including EGaIn volume,electrode voltage,NaOH solution concentration and electrode diameter）. Generalized additive model （GAM） was used to systematically analyze the multivariate interactions and reveal the nonlinear effects of various factors on the resistance. Compared with the traditional linear regression method,GAM can effectively handle the interaction effects between multiple variables. The results are of significant importance for enhancing the efficiency and safety of electrochemical sensors in various fields,such as environmental monitoring,energy storage,industrial process control,and smart wearable devices.
