摘要
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。
The pinpoint peak point is the key to reduce the Frank-Hertz experimental error. By using the unde-termined coefficient method to calculate the peak curve equation near the point,and then on the curve equation derivation,reached maximum points,so as to determine the peak and valley points. At the same time,the calcu-lation of language processing in the process of calculation data using efficient MATLAB project, make a complex mathematical operation becomes simple.
