【摘要】 在陈欣[2 ]等人研制的硫酸根离子浓度快速分析仪的基础上 ,设计了一套基于个人计算机的硫酸根离子浓度测试系统。该系统采用自适应滤波消除工频等噪声干扰 ,克服了原有快速分析仪的误差大等缺点。更多还原

【Abstract】 In this paper,a new system for measuring density of SO 4 2- is presented through combinating thermo reaction with smart pyrometric system.Based on personal computer,a system measuring the density of SO 4 2- is developed.Results show that this system can measure the density of SO 4 2- not only rapidly but also accurately.It can be used for online measuring.更多还原
