volume charge

The positive charge in the atom is spread over the whole atomic volume.

原子中的正电荷分布在整个原子体积上.

By the charge density we mean the per unit volume.

所谓的电荷密度是指单位体积的电荷.

Within the remainder of the dielectric the net charge per unit volume remains zero.

在电介质的其余部分,单位体积的静电荷仍为零.

By increasing negative surface, controlling the charge state of positive and negative and controlling electrolyte volume in cell, we have solved the problem of oxygen combination during charge so that the internal balance pressure of charged battery was only 0.045 MPa.

通过增大负极面积、控制正负极荷电状态和电液量，较好地解决了充电时氧气的迅速复合问题，使电池充电平衡内压达到0.045MPa；

A preliminary discussion is made on surface charge distribution on the borehole wall and volume charge distribution in the flushed zone in a borehole by using the theoretical results.

应用所得理论结果，对裸眼井井壁的面电荷分布和地层冲洗带内的体电荷分布情况作了初步的探讨。
