摘要
计算物理学中的曲线积分时,容易犯两个错误,一个是把线元的大小和坐标的微分关系搞错,另一个是把电流的正负搞错.详尽分析了这两个错误产生的原因,所得结果对改进物理学中的曲线积分计算的教学具有一定的参考价值.
When calculating the curve integral in physics,two mistakes are easy to be made.One is to mistake the relationship between the magnitude of the curve element and the differential of the coordinate,the other is to mistake the positive and negative of the electric current.The causes of the two mistakes are analyzed in detail,and the results obtained have certain reference value for improving the teaching of curve integral calculation in physics.
