与在电极上凿孔不同的是，他们在电极上覆盖一层碳纳米管，每个只有5纳米(十亿分之一米)宽。

Instead of digging holes in the electrodes, they are coating them with a forest of carbon nanotubes, each five nanometres (billionths of a metre) wide.

在水尚未流经缆绳前，研究团队无法确定，融化的水是会流入粒雪中，还是会聚积在钻头的周围。如果是后者，将会使凿孔因冻结而封闭。

Until water flowed through the tether, the team could not tell if the meltwater was draining into the firn or accumulating around the drill, which could freeze the borehole shut.
