摘　　要：分析了静电能量、静电场能量的来源、分布区域、差别与联系，指出，静电能量是带电体内电荷之间的相互作用能，它是由电荷携带的，定域于电荷存在的空间中。静电场能量是散布在场存在的空间中，是由场携带的。静电能量和静电场能量是相互伴随产生和消失的，这正是静电场能量到底是由场携带的还是由电荷携带的在静电场的情况下无法判断的原因。静电场能量和静电能量在数值上是相等的，这为静电场能量的测量提供了一条有效的途径。建议将静电能量和静电场能量区别开来，这有助于教和学，有助于进一步完善电磁学理论体系。In the paper, we analyze the origins, distribution areas, differences and relationship of the electrostatic energy and electrostatic field energy, point out that the electrostatic energy is the interactive energy between the charges in the charged body, carried by the charge, stationed in the space within the charge; the electrostatic field energy is scattered among the space within the field, carried by the field. They grow up and vanish side by side, which is the reason why the electrostatic field energy cannot be determined under the condition of electrostatic field. They are equal in number, which offers an effective means to measure the electrostatic field energy. It is advisable to distinguish the electrostatic energy from the electrostatic field energy, which is helpful to the teaching and learning, and also the improvement of the system of electromagnetic theory.
