前言在选矿试验中,得到的试验结果是一组离散点。为了便于观察和分析研究问题,有必要将这些离散点按一定规律连成一条曲线。这条曲线要尽可能符合试验的实际情况,即能较真实地反映出试验中各因素与选矿指标之间的关系。本文介绍两种用夏普PC-1500计算机绘制选矿曲线的方法,并结 Preface In the beneficiation test, the test result obtained is a set of discrete points. In order to facilitate the observation and analysis of research problems, it is necessary to connect these discrete points according to certain rules into a curve. This curve should be as far as possible in line with the actual situation of the test, that can more accurately reflect the test of the various factors and the relationship between beneficiation indicators. This article describes two methods of plotting mineral processing curves with a Sharp PC-1500 computer and concludes
