When we evaluate the property of contact materials, we should not only compare thier arctime, but also compare thier erosion rate of materials and arc energy.
作为评价触头的性能，不能单一地比较其燃弧时间的长短，尚应全面评价其分断电弧能量和材料侵蚀率。

During the arctime, changing rate of current could be adjusted by modulating the parameter of the control circuit, which ensures the proper output power of the arc.
在燃弧阶段，调节控制回路参数，控制燃弧电流的变化速度，保证充足的燃弧能量。

The influence of microwave radiation time, arctime and the mass ratio of KOH and coconut shell chars on the specific capacitance of the activated carbon were studied.
