本科毕业论文论文题目影响电导率仪测量精度的因素及分析作者姓名刘凤娟专业名称应用物理指导教师孙卫建 20 16年 4月 15日伊犁师范学院物理科学与技术学院 2016 届应用物理学专业毕业论文 I 摘要电导率分析仪表是利用溶液成分和电导率之间的关系分析溶液成份的仪器, 它可以用于有效检测蒸馏水水质状况,保证药用蒸馏水质量;有效监测锅炉和大型发电机组的水质状况,保证设备安全运行;可以有效监测纯净水、自来水的水质状况,保证供水质量等。随着经济的发展电导率检测仪器的应用范围越来越广, 与人民生活的关系越来越密切,所以对电导率分析仪表及其测量精度的研究越发显的重要。本文在说明电导率测量原理和电导率仪工作原理的同时,具体分析了电导率仪在测量过程,干扰电导率仪测量的诸多因素,并着重对影响电导率仪测量精度的主要因素进行了细致分析并提出了相应的解决方法。关键词: 电导率,分布电容,电导池伊犁师范学院物理科学与技术学院 2016 届应用物理学专业毕业论文 II Abstract Electric - conductibility instrument is the instrument which can analyze solu t ion ’ponent by relation between electric-conductibility and solution . It can inspect the quality of distilled water , and keep distilled water ’s quality ; itc an inspect quality of water which works in boiler and power plant ; itc an inspect quality of drinking water . So following the development of economy , the using of Electric - conductibilit y instrument e more and more broad and the relation between Electric-conductibility instrument and people ’s life e closer . The paper in tr oduces the theory of Electric-conductibility instrument and how it work ; introduces the interferential factor and puts forward the relevant resolvents of same main factors . Keywords: specific conductance , conductivity meter , pensation 伊犁师范学院物理科学与技术学院 2016 届应用物理学专业毕业论文 III 目录摘要....................................................................................................................................
