When you train over a period of time your heart will grow in size, allowing it to pump a larger volume of blood with each stroke (or pump).
当你运动训练过一段时间以后，你的心脏体积将变大，每一次跳动(或撞击)可以输送更多的血。
Reciprocating pump flow and pressure head has nothing to do with the pump cylinder size, and the reciprocating frequency of the piston stroke.
往复泵的流量与压头无关，与泵缸尺寸、活塞冲程及往复次数有关。
This is convenient since when killing the well the pump stroke counter will be used to determine how far the kill has proceeded.
这样做很方便，因为压井时，将使用泵冲记数器来决定已进行的压井走了多远。
