超级电容器似乎能够兼备速度和耐久性这两个优势，这是因为和电池类似，在构造上它采的是用离子和电解液而不是简单依靠静电荷。
The reason ultracapacitors may be able to bridge the gap between speed and endurance is that, like batteries, they use ions and an electrolyte rather than simply relying on the static charges.
这里有一个平衡，引力的平衡，由于氯离子带有负的净电荷，钠离子带有正的净电荷，但是它们两个，没有考虑净电荷，电子。
And there is this separation which is a balance of attractive forces because the chloride is net negative and the sodium is net positive, but both of them, regardless of net charge, have electrons.
在环内中性等离子体情况下计算了传输过程中的两个重要参量——平衡半径和空间电荷力平衡半径，讨论了电子束的传输特点。
Two important parameters-balance radiuses and space charge force balance radius is calculated under neutral plasma case. The properties of electron beam transmission are discussed.
在一个实施例中，电子受到磁场力的约束，离子受到因两种流体的电荷分离产生的内部静电力约束。
In one embodiment, electrons are confined by magnetic forces and ions by internal, electrostatic forces that arise due to charge separation of the two fluids.
这反映了C记离子在两类土壤固液两相间的分配比例不同，并与土壤的表面电荷特征、吸附解吸条件有关。
All of these are closely related to the charge character and condition of Cu2 + adsorption-desorption of soils.
