摘　　要：分析了几种教材中关于复杂电路的独立回路选择方法，并讨论了各自特点．Based on Blot- Savart law applied in the magnetic field produced b y steady current, a property theorem that the magnetic field of inverted symmetric current- element pair distributes on its symmetry plane has been proved strictly with space analytic geometry and theorem of vectors operation. Meanwhile, some examples have also been given in illustration of its application.
