您要查找的是不是：
- The stroke is the distance the piston travels from BDC (Bottom dead center) to TDC(top dead center). 行程是活塞从下止点运行到上止点的距离。
- The stroke is the distance the piston travels from BDC (Bottom dead center ) to TDC(top dead center ). 行程是活塞从下止点运行到上止点的距离。
- Upper limit of the piston movement is called as TDC (top dead center), and its lower limit is called as BDC (bottom dead center). 活塞运动的上限称为TDC(上止点)，下限称为BDC(下止点)。
- The Bore is the diameter of the cylinder. The stroke is the distance the piston travels from BDC (Bottom dead center ) to TDC(top dead center). The Bore is always mentioned first. 内径指的是气缸的直径;行程是活塞从下止点运行到上止点的距离。表述时,内径总是写在前面。

- The dead center, being a stationary bearing point, must be lubricated. 由于是固定的支承点，死顶尖必须润滑。
- after bottom dead center 下止点后
- The arrow hit the target dead center. 那支箭正中靶心。
- BDC - Bottom dead center. The bottom-most position of the engine piston stroke. 下止点。引擎活塞在燃烧推动下到达的最低位置。

- Yet monarchs of old always dined dead center and many time in public. 然而，古代的帝王经常是公然地坐在正当中进餐。
- Two TDC (Top Dead Center) sensors are mounted at the rear of the single camshaft. 两个上死点的传感器安装在凸轮轴的后面。

- But dead center is no dead zone: Billions of organisms called thermophiles flourish in the scalding water. 但是温泉的中央也并不是死气沉沉，数十亿的嗜热性生物在滚烫的温泉水中活跃着。
- This spark must occur near the end of the compression stroke, as the position approaches top dead center (TDC). 火花应该在接近压缩行程终了的时候产生，即活塞位于接近上止点（TDC）。
- The wind whirled the dead leaves about. 风吹得枯叶在四处回旋。
