以光学实验中的几个典型实验为例, 简述了光纤在光学实验中的应用. 不仅提高了原有的光学实验的观测效果, 还可以增加新的实验内容, 改进实验装置, 使一些原来在一般实验室条件下无法观测到的光学现象能够很容易地观察和定量测量. 相似文献

精确地找出峰值和谷值点,是减小弗兰克-赫兹实验误差的关键。通过用待定系数法求出各峰值和谷值点附近的曲线方程,再对曲线方程求导,得出极值点,从而确定峰值和谷值点。同时,利用高效的MATLAB工程计算语言处理计算过程中的数据,使复杂的数学运算变简单。 相似文献

MATLAB在普通物理教学中的应用 总被引:8,自引:0,他引:8
在普通物理教学中,大学生常常接触较多的数学公式,由于他们的知识不完整,对其物理意义理解不深,人们通常借助计算机辅助教学.因此我们尝试在普通物理教学中引入数学软件MATLAB,进行计算机辅助教学,运用MATLAB的可视化技术,绘出随时间和空间变化的物理量或物理现象的图形和图象,帮助大学生理解物理意义. 相似文献

MATLAB用于大学物理教学 总被引:8,自引:0,他引:8
自从在理论力学教学中成功开展计算机模拟实验以来,被誉为第四代计算机语言的MAT—LAB逐步受到了物理教学工作者的关注.的确,MATLAB具有强大的数学运算能力、方便实用的绘图功能及语言的高度集成性,使编程者从繁琐、无谓的底层编程中解放出来,从而加大了将物理教学 相似文献

The beta function measurement is used to detect the shift in the betatron tune as the strength of an individual quadrupole magnet is varied. A GUI (graphic user interface) tool for the beta function measurement is developed using the MATLAB program language in the Linux environment, which facilitates the commissioning of the Shanghai Synchrotron Radiation Facility (SSRF) storage ring. In this paper, we describe the design of the application and give some measuring results and discussions about the definition of the measurement. The program has been optimized to solve some restrictions of the AT tracking code. After the correction with LOCO (linear optics from closed orbits), the horizontal and the vertical root mean square values (rms values) can be reduced to 0.12 and 0.10. 相似文献
