The technology of removing the low concentration carbon dioxide in the atmosphere is essential for the life sustain in the area of manned aircraft, submarine, working at the borehole pump and so on.

大氣中低濃度二氧化碳清除技術是載人航天器、潛水艇、深井作業等領域所必備的生命維持技術。

The fluid and fine sand in the borehole enter the subsurface pump through the liner and then lifted to the ground.

井筒內液體和細小砂子通過篩管進入抽油泵內舉升到地面。

The heat transfer of ground heat exchanger is enhanced by changing backfill materials for reducing the thermal resistance of borehole and controlling heat pump operation mode for delaying the soil temperature rise speed.

本文通過改變回填材料減小鉆孔內熱阻和控制熱泵運行模式延遲土壤溫升來強化埋管換熱器的傳熱，提高系統運行效率。
