用Mathematica处理和分析实验数据

Processing and Analyzing Experimental Data with Mathmatica

主要讨论了数学软件Mathematica在实验数据处理中的优点,并且具体给出了“在不良导体导热系数的测定”实验中的应用。充分利用软件内部的曲线拟合、斜率函数、作图函数、计算等功能对实验数据进行处理,最终得到的导热系数与理论值相差非常小。数学软件Mathematica的应用不仅减少了手工计算量而且减少了实验误差,而且结果准确。

This article mainly discussed the advantage of processing experimental data with mathematical software “mathematica”,and presented an experimental example in “dating thermal conductivity in poor conductor”. It makes full use of functions in the mathematical software such as curve imitation, slope function, plot function, calculation to deal with experimental data, rusulting in that the mistake between theoretical value and experiment value is very small. The application of mathematical software “mathematica” reduces not only the calculation by hand but also the experiment mistake,and the result is very precise.
