摘要/Abstract

摘要： 本文克服了dE/dt～E曲线线性范围窄、分辨率差等缺点,把dE/dt～E曲线的切口变成峰形,具有再现性好、线性范围宽、灵敏度高、分辨率好等优点.采用内标法和频谱分析进行了定量测试工作,取得了满意的结果.

关键词: 改进示波计时电位法, 内标法, 频谱分析

Abstract: This paper presents a new method which improved osciilographic chronopotentiometric method.This method can improve dE/dt～E curve and can overcome some drawbacks of dE/dt～E curve.It changes incision of dE/dt～E curve into peak and has the advantage of a good re-producibility,wide linear range and high sensitivity.As using it,we applied inner marker method and frequency-spectrum analysis to carry out quantitative analysis,satisfactory results were obtained.

Key words: Improved oscillographic chronopotentioroetric method, Inner marker method, Frequency-spectrum analysis
