| 摘 要： | 从亥姆霍兹定理出发，阐明了电位移与场源之间的内在联系，指出电位移不仅与自由电荷分布有关，而且还与电介质、极化电荷及边界条件有关；着重分析了电位移仅与自由电荷分布有关的条件。

| Abstract: | From the perspective of Helmholtz's theorem,the inherent relationship between electric displacement vector and the source is made clear,and that the electric displacement vector is relevant to dielectric,polarization charge and the boundary conditions as well as the distribution of free charge is pointed out,putting emphasis on the prerequisites for interaction between electric displacement vector and the distribution of free charge. |
