every piece, the stiff, hollow pipes that connect the drill assembly with the rig at the surface have to be assembled as the drill is lowered and dismantled when it comes up again.───每一段坚实、中空的连接钻取机索导管的冰芯只能被切碎，因为钻取机再次出来时变得更低了也更细了。
mechanical model for the offset-axes pendulum drill assembly (OAPDA) was established according to the continuous beam theory and the d.───连续梁理论和达朗伯原理，建立了偏轴钟摆钻具组合动力学分析模型。
A drill assembly is typically a few tens of metres long and can only hold a core of ice of the same length.───一个钻取机通常有数十米长而且只能获取一个与之等长的冰芯。
