稳恒电磁场中的坡印廷定理和I^2R发热的另一种解释

The Stable Electromaagnetic Field's Poyntings Theorem and a New Explain for I^2R Heating Effect

把时变电磁场中的坡印廷定理引入至稳恒电磁场中 ,在稳恒电磁场中分析穿过导体表面的能量流动问题 ,并对通常人们所熟悉的 I2

Take the variable electromagnetic fields Poyntings Ther or em to the stable electromagnetic field, and study the energys flow through the conductors surface in the stable electromagnetic fiecd, and afford a new expl ain for I 2R heating effect.
