内外两部分之间通过钻孔壁温耦合连接。
The inside part and outside part are combined with the temperature of borehole wall directly.
然后通过钻杆和钻孔壁之间的间隙返回至地表。
And returns to the surface in the space between the drill pipe and the wall of the borehole.
实验结果表明：1）在周期性脉冲热流的作用下，钻孔壁温度呈周期性震荡并逐渐升高；
The results show that:1)Under a periodical pulsed heat generation, the temperature of borehole wall has a fluctuant rising tendency;
