positive wire

The welding wire is connected to the positive electrode when used with DC.

可交直流两用,直流时焊丝接正极.

To analyze the formation of surface discharge on a dielectric plate under positive nanosecond impulse voltage in air, a wire to plane electrode system with a barrier of negative film was used.

采用感光胶片作为阻挡介质的针-板放电系统，解析空气中固体电介质上纳秒正脉冲表面放电的形成过程。

The red wire goes to the positive terminal. Get it?

那个红电线接在正极接线柱上，明白了吗？

The result showed that it is in the period of droplet growth at the tip of welding wire that an electrochemically gained oxygen was produced in the case of direct current negative polarity whereas an electrochemically lost oxygen in positive polarity.

结果表明，在焊丝末端熔滴生长阶段，直流反极性条件下存在电化学增氧，而直流正极性条件下则存在电化学脱氧。

The utility model relates to a miniaturized positive ion electrostatic field formed by an electric traveling band type flexible negative electrode and an auxiliary thin wire type positive electrode.
