摘要
从分析电容探测系统电极的自电容、互电容的角度,推导出有源屏蔽电极在理想情况下探测电极与探测基极之间的等效电容计算式;对比分析了有源屏蔽电极探测系统与无屏蔽电极探测系统的等效电容,通过分析发现有源屏蔽电极探测系统的等效固有电容远小于无屏蔽电极的探测系统;通过实验验证了推导结论的正确性.
The equivalent capacitance formula of capacifelector （driven shield capacitance sensor ） is given by the mutual capacitance and the self capacitance of electrodes in the thesis. Comparing two cases of the capacifelector and the capacitance sensor without shield electrode, the result is found that the equivalent capacitance of capacifelector is less more than the one the capacitance sensor without shield electrode, and verified by experiment.
