| 摘 要： | 以番茄果实为试材,在对真空和空气中的平行板电场进行电磁学分析基础上,研究了下极板摆放果实时平行板电场,中间插入金属板并摆放果实时平行板电场,中间插入电介质并摆放果实时平行板电场。结果表明,在极板间添加番茄后,由于增大了极板组成的电容器电容,造成极板电荷增大,空气层场强增大,番茄层场强相比于E_0有所减少;当电容器下极板摆满一层果实,并且在平板中间插入金属板,其上也摆满果实时,所组成的电容器等效电容C有所增大,极板上富集电荷Q有所增大,空气层场强相比于E_0有所增大,但E_f相比于E_0会随h及ε_h的不同产生变化;当电容器下极板摆满一层果实,并且在平板中间插入一层电介质,其上也摆满果实时,所组成的电容器等效电容C有所增大,极板上富集电荷Q有所增大,空气层场强相比于E_0有所增大,但E_f及E_h相比于E_0会随h及ε_h的不同产生变化。

| Abstract: | Based on the electromagnetics analysis about the parallel electric field in vacuum and air,tomato is taken as the experimental material,and put the fruit into three kinds of parallel electric fields are studied.The results indicate that the tomato field-strength is lower than E_0 by put the tomato in the electrode plate.The C and Q increase by the effect of the capacitor with metal plate and the capacitor with dielectrics.The increase of air field strength is more than E_0,the E_f,E_h vary with h andε_h. |
