zero-extended field

The dependent equations, given in this paper, of the classical electromagnetic field in three dimensional space are initial conditions that make the integral constant equal to zero.

本文给出的在三维空间中经典电磁场非独立的场方程，就是使积分常数为零的初始条件。

In the cylindrical and spherical coordinate systems, all the field component fields have merely one zero line and are characterized by half-plane distribution.

在柱坐标和球坐标系下，所有场分量都只有一条零线，场为半平面分布状态。

The radial distribution function, common neighbors, internal energy and volume of the system were recorded during the processes. The atomic internal energy, atomic Voronoi volume and atomic stress field of the relax system were analyzed at zero temperature.

记录了系统能量、体积、径向分布函数及公共近邻的变化，并在0K分析了弛豫后系统原子内能、原子Voronoi体积及原子应力等热力学性质的分布情况。

To enter a zero-length string in the field, type two double quotation marks without a space in between(″ ″).

若要在字段中输入零长度字符串，请键入中间不带空格的双引号（〃〃）。

The article points out that the "I" of the Biot-Savart law includes not only conduction current but also displacement current, and certifies that displacement current's contribution to magnetic field is zero.

指出毕奥&萨伐尔定律中的I不仅只包含传导电流，也应包含位移电流，证明在一定条件下位移电流对磁场的贡献为零。
