Weld penetration and wire melting speed of AC PMIG welding not only have relationship with welding current but also with electrode negative ratio.

交流脉冲MIG焊其焊缝熔深及焊丝熔化速度不仅与焊接电流有关，而且与负极性比率有关。

Each cell consists of a negative electrode and a positive electrode kept apart by a separator soaked in a conductive electrolyte that allows ions, but not electrons, to travel between them.

每个电池元都包括一个正电极和一个负电极，两个电极用一个浸在导电电解液中的隔离器隔开，该电解液允许离子而不是电子在两个电极之间来回传输(译者注：具体参见下面那个电池结构图)。

As the battery discharges, the lithium ions swim from the negative-electrode lattice to the positive one; during recharging, they swim back again.

当电池放电的时候，锂离子从负极栅格游到正极栅格；充电时它们游回来。

In an ultracapacitor, positively charged ions gather on the surface of the negatively charged electrode and negative ions on the surface of the positive electrode.
