本仪器不仅能完成平行板电容器的电容跟哪些因素有关的演示实验,同时还能演示匀强电场电力线的分布情况、电荷间的相互作用、气体的导电性等实验,并可兼作起电盘使用.达到具有一机多用,装拆方便,操作简单,经济实用的目的.二、仪器结构本仪器的结构与传统产品相比有其独特之处.它由两块置于底座1上的带有机玻璃棒柄2的圆铝板3,一件带有玻璃棒柄的介质板5(由有机璃玻板制成),附一件穿有均匀丝线的电力线板6和一个穿有500mm细线的感应球7组成,如图1所示.
This instrument can not only complete the demo experiments related to the capacitance of the parallel plate capacitor, but also demonstrate the distribution of the uniform electric field power lines, the interaction between the charges, the conductivity of the gas, etc., and can also be used as the electrification plate. Achieve the purpose of having a multi-purpose machine, easy assembly and disassembly, simple operation, economical and practical. Second, the structure of the instrument The structure of the instrument has its unique features compared with traditional products. It consists of two pieces of organic material placed on the base 1. Round aluminum plate 3 of glass rod holder 2, a dielectric plate 5 (made of organic glass) with a glass rod holder, a power line plate 6 with a uniform wire, and a sensor with a 500 mm thin wire The ball 7 is composed as shown in Figure 1.
