How could the rate of depletion be increasing over the first 5 hours while the rate of current draw is relatively steady?

手机的耗电率怎么可能在头5个小时不断增加，同时电流却相对稳定？

During the arc time, 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。
