用大学的微积分和矢量分析对高中及中专物理教材中的左手定则、右手定则、右手螺旋定则作了全面分析 。

This paper analyses left_hand rule,right_hand rule and right_hand screw rule which appear in middle school and special secondary school according to differential and integral and vector analysis which appear in college.Also, the paper reveals the reletions between this two series methods of a single phenomenon.This will help us apply the three rules to practice and seek unity of the rules in terms of theory.
