本文介绍了一种在JES-FE型ESR谱仪上进行数据采集、信号平均、并具有数据平滑、g值计算、积分、加减谱、绘图等数据处理功能的计算机系统。系统由IBM-PC微机和由时钟脉冲电路、A/D转换电路等组成的接口、电路及应用软件组成。该系统可在扫场速度1ms—128min的广泛范围内采样及信号平均。该系统大大提高了ESR谱仪在短寿命自由基测定及微弱信号检测方面的应用。其主要功能和技术指标已达到该机原配套的ES-PRIT23系统的水平,但价格不及其五分之一。
In this paper, a computer system for data acquisition, signal averaging, data smoothing, g value calculation, integration, addition and subtraction spectrum, drawing and other data processing functions is introduced in JES-FE ESR spectrometer. System consists of IBM-PC microcomputer and by the clock pulse circuit, A / D conversion circuit composed of interfaces, circuits and application software. The system can sweep the speed of 1ms-128min wide range of sampling and signal averaging. The system greatly improves the ESR spectrometer in short-lived free radical determination and weak signal detection applications. Its main functions and technical indicators have reached the level of the original supporting ES-PRIT23 system, but the price is less than one-fifth.
