Current global warming from greenhouse gases generated by human activities could warm the arctic to levels above the melting point of ice, the study said.
该研究称，人类活动产生的温室气体所造成的当前全球变暖可能使北极暖化程度高于冰的融点。

Critical current of ice-melting increases along with the increase of wind speed and the decrease of temperature increase, while the size and thickness of ice is not obvious.
临界融冰电流随着风速的增大而增大、随环境温度的降低而增大，而与冰层厚度的大小关系不明显。

Two Critical concepts involved in direct currentice-melting technique of high voltage over head line, the least ice-meltingcurrent and the Max allowed current was presented.
