Through this experimentation, it indicates that the sampling bit added pumpinghole ADAPTS to drilling in most fragmentized strata.
试验表明，增加了抽吸孔后的取样钻头适合在极其破碎的地层中钻进。

Not only was Aisha born without a breast bone, but her heart was malformed, with a hole between the two pumping chambers and a restricted artery leading to the lungs.
爱莎出生时不仅没有胸骨，而且心脏是畸形的，两个心室之间有一个洞，一根较常人短些的动脉通向肺部。

By the project performance, it has introduced some methods such as geophysical prospecting, dynamic and static strain observation to study the relation between drill-holepumping and land deformation.
