中文说明：本程序通过计算节点，对两块极板间的电容值进行MATLAB程序设计，得出了两块极板间的电容值，思路简单，清晰，同时避免了杂散电容的干扰，误差相对减少。
English Description：
This program through the calculation node, carries on the matlab program design to the capacitance value between the two plates, obtains the capacitance value between the two plates, the idea is simple, clear, at the same time avoids the stray capacitance interference, the error is relatively reduced.
