钟摆

It is recommended to adopt air hammer, pendulum assembly and air motor to minimize or eliminate the well deviation during gas drilling.

建议在现场推广应用空气锤、钟摆钻具组合和空气螺杆钻具组合三项气体钻井防斜技术来防止气体钻井井斜。

His comprehensive apprehension about the appendix of the pendulum is obvious.

他的关于钟摆的附录的广泛理解是明显的。

The sewing machine, the pharmaceutical balance, the caduceus, the clock with the pendulum that still moved, the linocut of the Hippocratic Oath, the rickety rocking chairs, all the things I had seen as a boy were still the same, and in the same place, but transfigured by the rust of time.

那台老式缝纫机、秤药剂的小秤、手杖、那个钟摆依然在摆动的大钟、刻着希波克拉底誓言的浮雕、还有吱噶吱噶响的椅子，所有一切都跟我小时候看到的一样，但现在看来，时间让它们生锈变形。

That the rate of a clock moving through space will decrease as its speed increases

在空间移动的时钟钟摆频率会随着运动速度的增加而减慢

This concept was based on the n ive notion that the pendulum would "fall over" as the rocket turned at the peak of the trajectory.

这个概念的基础上， n ive概念，即钟摆会"跌倒"作为火箭拒绝在高峰期的轨迹。

This is a simple flash animation display, with a simple pendulum graph drawing and brush drawing, create multiple layers, adjusting frame to achieve the pendulum action.

详细说明：这是一款简单的flash动画展示，用简单的画图和笔刷绘制钟摆图形，创建多个图层，调节帧来实现钟摆的的动作。

"We were looking at the slow steady swing of the pendulum as it counts the seconds," the younger one said,"and my friend has said it would be easy to stand in front of the clock for one hour, to stand without moving and say 'here it comes, there it goes' as the clock's pendulum swings back and forth."

"我们再看钟摆慢慢摆动计算时间，"年轻一些的人说道，"我朋友说在钟前站一小时很容易，要站着不动，还得在钟摆摆动时说：'摆过来，摆过去'。"

ENG recorded tow kinds of nystagmus waveforms,included subsultus waveform as saw tooth wave and pendulum waveform as sinusoidal wave.

眼震电图可以记录到跳动型和钟摆型两种不同的眼震波，跳动型呈锯齿波，钟摆型呈正旋波。

The technical characteristic of a pendulum drill assembly is to lose "penetration rate"in order to get"dropping angle", but sometimes a pendulum drill assembly can't meet the need of drop—off hole angle, which results in longer completion well cycle and more drilling cost.

防斜打直是常遇到的钻井技术问题，防斜的钻具组合是满眼钻具，纠斜的钻具组合是钟摆钻具，当满眼钻具满足不了井斜控制的要求，就必须强迫起钻换钟摆钻具，而钟摆钻具的技术特点是损&快&保&直&，有时还达不到纠斜要求，导致较长的建井周期和较高的钻井成本。

The machine flies with more power in that it bogs very little compared to the flybar 700, especially in elevator, aileron tick tocks and big ben type maneuvers. Less attention to collective management is necessary with this additional power and you can focus more attention to you cyclic inputs. The cyclic is sure and powerful with no bobble at the stops in the tic tocs.

700搭配无平衡翼系统飞行时源源不断的动力，是传统系统无法比拟达到的，特别是在升降前后、副翼左右钟摆及十二点钟摆这类的动作，这额外的动力可以让你更专注在控制十字盘的动作上，少些注意力在集体螺距的控制，在执行钟摆动作的顿点时，十字盘的动作是准确、有力的，而且无抖动。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
