近代物理实验中的计算机应用

摘要

为了更充分适应在智能条件下的近代物理实验，需要了解计算机在近代实验中的作用．文章借助几个典型的微机型近代物理实验一核磁共振、顺磁共振、塞曼效应以及原子光谱实验，从数据采集和数据处理两方面研究了近代物理实验的智能化方式．数据采集可归结为两种方式，一种是借助于计算机自带的多媒体设备接收数据，另一种需要安装图像采集卡，并需要在电脑安装设备驱动程序．数据处理是近代实验智能化的主要目的，结合钠原子光谱实验，借助专用软件，快速处理数据，并给出可视化结果．研究结果有助于更好利用计算机，使计算机在近代物理实验中更好地发挥其作用．%In order to better master the modern physics experiments under intelligent conditions, we need to know the computer＇ s role in modem physics experiment. With the help of a few examples of computer-based modern physics experiment, such as NMR, EPR, Zeeman effect and atomic spectra, the intelligent ways of modem physics experiments axe studied from data acquisition and processing. Data acquisition could be attributed to two ways ; one way is by means of computer＇ s multimedia device to receive data, another way by means of installing the frame grabber, to be accompanied by installing device driver in the computer. Modem experimental data processing is the main purpose of the intelligentization, combined with sodium atoms spectral experiment, with special software, data processing is done quickly, and visual results are given. The results contribute to a better use of computer, and make the computer play a powerful role in the modem physics experiment.
