| 摘 要： | 电磁场能流矢量的非唯一性,是国内外物理学考长期争论的问题之一。本文对此提出了自己的见解,指出这种分歧的实质性所在。对表示电磁场能流的坡印亭矢量和斯列潘矢量的意义、性质及其区别作了分析比较,指出了坡印亭矢量的应用范围,并由斯列潘矢量导出了与电阻、电容、电感以及辐射电阻等电路参数相对应的电磁场能流矢量模型。

| Abstract: | The non-uniqueness of electromagnetic field energy flow is at issue among physicists over a long period of time. In this paper, the essence of the difference is proposed. The meaning and characteristics of poynting vector and slepian vector which can express the electromagnetic field energy flow and the difference between them are analyzed and compared. Application range of poynting vector is pointed out. At last, the electromagnetic field energy flow model with regard to the electric circuit parameters such as resistance, capcitor, inductance and radition resistance is derived from the analysis of slepian vector. |
