TDC (top dead center) - the position of the crank and piston when the piston is farther away from the crankshaft.
(上止点)-当活塞离曲轴最远时，曲柄和活塞的位置。
For a CNG engine, the cylinder pressure signal, gear pulse signal and top dead center pulse signal were simultaneously collected.
对某天然气发动机缸内压力信号、齿盘脉冲信号和上止点脉冲信号进行同步采样。
Upon returning, I unlocked the door and was surprised to find a footstool that had been in the living room in the dead center of the kitchen.
一回来，我打开门，惊奇地发现原本放在客厅里的一个脚凳，现在摆在厨房的正中间。
Further, the piston is operated at the top dead center position and in the resonance state under all load conditions, thereby further increasing operation frequency.
此外，在所有负载条件下将活塞操作在上死点和共振状态，从而进一步增加操作频率。
The studies show that the ability of systemic pressure generation is involved with sealing clearance, dead center volume, pressure intensifying speed and volume of discharged oil.
研究表明：系统的压力生成能力不仅与密封间隙相关，同时与系统的死点容积、增压速度及排液容积相关。
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 experimental results show that the algorithm can avoid the misclassification of FCM such as dead center, center overlapping and local minima, and accelerate the segmentation speed.
实验结果表明，该算法可以避免FCM的误分类，诸如陷于中心死区、中心重叠和局部极小值，而且提高了分割速度。
The top dead center (TDC) phase has a great effect on the result in the combustion analysis of internal combustion engines, so it is very important to obtain the dynamic TDC phase correctly.
在进行内燃机燃烧分析时，上止点相位对分析结果影响很大，正确确定内燃机动态上止点相位显得非常重要。
The results of calculating and experimenting show that the first and largest slap of impact between the piston and the liner occurs around the top dead center from the nonthrust to the thrust face.
经计算和实验表明：活塞在上止点附近，当活塞由非推力面快速地移向推力面时，对缸套具有较大的冲击能量。
