一、前言目前,在热处理行业对淬火介质的研究、生产和使用过程中的性能检测问题引起了广泛的兴趣.自从微型电子计算机普遍推广以来,显得非常麻烦的传统检测方法变得轻而易举了.带微电脑的检测系统不但采样速度、采样时间可在大范围内调节,而且可以方便而精确地进行数据处理,并以曲线形式输出,还可将原始数据或计算结果存贮于磁盘上长期保留.类似文献〔1〕介绍的系统所采用的都是台 I. INTRODUCTION Currently, there is widespread interest in the performance testing of quench media in the heat treatment industry in the research, manufacture, and use of quenching media, and traditional methods of detection, which are troublesome since the introduction of microelectronic computers, have become a breeze. Microcomputer detection system not only sampling speed, sampling time can be adjusted in a wide range, and can be convenient and accurate data processing, and output in the form of curves, but also the original data or calculated results stored on disk long-term preservation.
