摘　　要：本文给出了用虚位移法计算静电场中电介质受力与用虚位移法计算静电场中导体受力的关系,从而说明了静电场中电介质受力的本质。阐明了静电场中电介质受力的计算可直接应用静电场中导体受力公式的原因,给出了计算介质受力时可以运用计算导体受力公式的条件,并给出了具体的例子进行说明。The paper gives the reason that in the electrostatic field the dielectric medium stress computation may directly apply the conductor stress formula. The condition when the computation medium stress may utilize the computation conductor stress formula is deduced. The specific example is given to explain that.
