Abstract: Based on the cloud computing platform，a program for assisting online data processing of sodium atomic

spectrum experiment and Frank-Hertz experiment is designed by the use of Python and Flask. It can be used

to calculate the quantum defect and fixed items of sodium atom，to draw the Frank-Hertz experiment curve without

geographical and equipment constraints. The function expansion is realized for college physics experiment teaching

resource based on cloud platform.

Key words: cloud computing, data processing, Python, Flask
