您要查找的是不是：
- lower dead center 下死点,见bottom dead center
- 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。
- The arrow hit the target dead center. 那支箭正中靶心。
- 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 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。
- 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。
- I was sitting in the dead center of the room so when I left early, everyone noticed. 我坐在正当中,所以提早离开时,全屋的人都注意到了。
- 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。
- 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。
- 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。
- 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 trailing edge of the fourth notch, which causes the pulse, is four degrees before top dead center (TDC) of the corresponding piston. 产生的脉冲的第四凹槽的后缘，位于相应的活塞在前上死点（TDC）4度的位置的位置上。
- If you arm Wesley with a nuclear launcher right now and place him dead center in middle of Moscow, he would miss Russia by 2 planets. 如果你现在让为私利装备上核武器发射器,然后把他放在莫斯科的市中心,他最后射出去的导弹会差俄罗斯2个星球。
- The spark is therefore timed to occur before the piston reaches top dead center, otherwise maximum pressure would not be reached in time. 因而，在活塞到达上死点前，火花便会发生，否则就不可能适时达到最高的压力。
- The top dead center (TDC) has a great effect on the measurement and analysis of combustion process of internal combustion engines. 在示功图测量分析中,精确标定上止点相位是必不可少的重要环节。
- Lisa watched a monitor, as a Crann under the flagship's bow was hit dead center by a laser cannon round, like a white-hot needle going through a beetle. 丽莎从一个监视器里看到，舰首下方一只克兰无机兽被一发激光炮直接打中中心部位，就像一支白热的针刺穿了一只甲虫。
- Useful or not ,though, I like to believe there's some merit in circling the issue of car dependence ,because a practical solution doesn't always lie at dead center. 可是，不管有用与否，我都愿意相信，围绕着小汽车依赖性这个议题来考虑事情是有可取之处的，因为切实可行的解决方法并不总在问题的死点上。
- Sherman recommended that Clarke be disciplined, but higher-ups rejected the idea. 谢尔曼建议对克拉克进行纪律惩戒，但高层拒绝了这个意见。
- 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。
