C语言在落球法测液体粘度实验中的应用

摘要

In the age of big data,in order to improve the processing efficiency in physical experiment,reduce artificial errors in data processing,this paper discusses the experiment of measuring liquid viscous resistance coefficient based on the Ball-Dropping method. Using efficient,structured and modular programming language and process-oriented programming technology,a C language program is written to apply to the liquid viscous re-sistance coefficient measuring experiment,and to calculate the relative uncertainty of the viscous resistance co-efficient according to the related theory,which further expounds the feasibility,superiority,generalizability and applicability of the C programming language in data processing of physical experiment,and brings up a high-ef-ficiency physics experiment data processing method combining the use of Excel and C programming language.%在大数据时代，为了提高物理实验数据的处理效率，减少数据处理过程中的人为误差，本文以落球法测液体的粘滞阻力系数实验为载体，运用高效率、结构化、模块化的编程语言，采取面向过程的编程技术，编写了适用于落球法测液体粘度实验的C语言程序，并根据相关理论计算了了粘滞阻力系数的相对不确定度，从而进一步地阐述了C语言程序设计在物理实验数据处理中的可行性、优越性、可推广性以及适用性，提出了Excel与C语言结合、高效率处理物理实验数据的方法。
