摘　　要：提出基于化学震荡反应的多参数测量系统的设计方案,此方案可用于测量化学震荡反应过程中的4路信号:电压、温度、pH及容器内压强.此方案能实时采集此4路信号,可解决化学振荡反应中出现的压值为负的问题,能利用软件分析系统对数据进行分析、处理、对比和显示,能直观反映参数间的关系.实验结果表明:给定值与测量值间相关系数的平均值高达0.998 74,因此该系统有高的测量精度.The authors put forward the design scheme based on oscillating chemical reaction of multi-parameter measurement system. The design could be used to measure four signals namely voltage, temperature, pH and the intensity of pressure simultaneously. Besides, it could solve the problem that voltage value was negative in the chemical oscillation reaction system. And it could analyze, handle with, contrast data and display graphs, and reflect the relationship between each parameter straightforwardly through software analysis system. The correlated coefficient average between measurements and set values was 0. 999 84, so this was a high accuracy system.
