摘　　要：植物病害诊断仪的使用效果确实可靠。然而对它的传感机理总觉得难以置信。对植物电阻、电势等变化 ,静态实验即可证明。而电容参量只有在动态下才具有可测性 ,因而实验繁难。本文在大量数据基础上以图解方式从 5个方面定性简述了植物具有电容 。The effect of Plant diseases diagnosis instrument is reliable indeed,but it is difficult to understand its sensor mechanism.It is easy to prove the change of resistance,electricity tendency of plants and so on by static experiment.But capacitance can be measured only at dynamic state,so the experiment is complex.Using diagrams,this text describes plants capacitance base on various datas to prove that plant have capacitance.And prove the authenticity of the sensor mechanism.
