从“关联速度”看“合成法”求匀强电场的电场强度

Solving the Electric Field Strength of a UniformElectric Field Using the “Synthesis Method”from the Perspective of “Correlation Velocity”

“合成法”求匀强电场的电场强度公式中的d不是沿电场方向的距离时,得出的电场强度是匀强电场的场强在d方向上的投影;匀强电场的场强与投影场强并非矢量的合与分的关系,“合成法”的本质关系应为投影关系.

When the“synthesis method”is used to calculate the electric field strength in uniform electric field,the d in the electric field strength formula is not the distance along the electric field direction,the electric field strength obtained is the projection of the electric field strength of a uniform electric field in the d direction;The relationship between field strength of a uniformly strong electric field and projection field strength is not combination or separation of vectors,and the essential relationship of the“synthesis method”should be a projection relationship.
