本文根据电力线基本性质,在教学中采用了APPLE-II所具有的高清晰图绘图功能清楚展现了电力线在电场中分布图形,从而克服了用一般方法演示电力线存在的弊端。
According to the basic nature of power line, APPLE-II has been used in teaching to clearly show the distribution of power lines in the electric field by using the high-definition graphing function, thus overcoming the drawbacks of using general methods to demonstrate power lines.
