摘要：基礎(chǔ)物理實(shí)驗(yàn)作為我校物理專業(yè)必修的一門課程，其實(shí)踐性不言而喻。其中電磁學(xué)實(shí)驗(yàn)是一門難度較大的課程，且實(shí)驗(yàn)也具有一定的抽象性，實(shí)驗(yàn)中較深的數(shù)學(xué)理論和場(chǎng)的抽象性使得學(xué)生在學(xué)習(xí)中往往有恐懼心理，很難產(chǎn)生學(xué)習(xí)興趣。我?，F(xiàn)階段的實(shí)驗(yàn)數(shù)據(jù)和圖像只是利用手工處理和描繪。這既浪費(fèi)了學(xué)生的時(shí)間，且處理得到的結(jié)果誤差較大。本文采用MATLAB軟件工具對(duì)電磁學(xué)中伏安法測(cè)電阻和制流電路與分壓電路的實(shí)驗(yàn)數(shù)據(jù)進(jìn)行處理，通過建立GUI（圖形用戶界面），運(yùn)用M文件實(shí)現(xiàn)圖形界面的函數(shù)回調(diào)，并將實(shí)驗(yàn)的最終結(jié)果（數(shù)值和圖形）顯示出來，實(shí)現(xiàn)了實(shí)驗(yàn)數(shù)據(jù)及圖像的集成處理，顯示了MATLAB在電磁學(xué)的計(jì)算及可視化方面的優(yōu)越性，較好地改善傳統(tǒng)實(shí)驗(yàn)手工處理數(shù)據(jù)和繪圖的方法。 關(guān)鍵詞： MATLAB；GUI；最小二乘法；數(shù)據(jù)
ABSTRACT：Basic Physics Experiment Physics as our school required a course, the practical self-evident. Electromagnetic experiment which is a difficult course, and the experiments have a certain abstract, experimental and field deeper abstract mathematical theory makes students in the learning of fear often difficult to generate interest in learning. My school at this stage the experimental data and image processing and painted by hand only. This is a waste of the student's time, and deal with the results obtained errors. In this paper, MATLAB software tool for electromagnetics voltammetry measurement system of flow resistance and the voltage divider circuit and the experimental data processing, through the creation of GUI (graphical user interface), the use of M file callback function to achieve a graphical interface, and The final experimental results (numerical and graphical) display to achieve the integration of experimental data and image processing, display the MATLAB calculation in the electromagnetic and the advantages of visualization, the better to improve the traditional manual processing of experimental data and drawing approach. Keywords: MATLAB; GUI; Least-square method ; Data |
