查询词典 impact bit

The impact was powerful, but a bit busy, if not cacophonous.

这个印象如果没有不和谐，那就很有震撼力，虽然有点眼花撩乱。

A model of the impact between the bit and the wall of well is set up. The impact is simplified as an impact of two cylinders. According to the coefficient of restitution obtained from experiment and the speed of the bit before impact, the speed of the bit after impact and the impacting force can be worked out.

通过建立钻头与井壁的碰撞模型，将碰撞简化为两个圆柱筒之间的碰撞，利用冲量定理和实验方法获得的钻头与井壁碰撞时的恢复系数及钻头碰撞前的速度，可计算出钻头与岩石碰撞后的速度和碰撞时产生的碰撞力。

Start collaring with reduced throttle to the impact mechanism and feeding, let the bit work its way slightly into the rock.

开孔时，应采用最小的冲击和推进力，使钻头平稳地进入岩层。

Ben - With a better knowledge of the impact of building a dam, are we now in a position where we can predict a bit better what would happen if we were to build a dam or if we were to decommission one?

Ben-既然我们对建设大坝的影响认识得更透彻了，那我们现在是否可以更好地预测建坝和撤坝的影响呢？

The bit error rate performance for ultra-wide band indoor communication with impact of metallic furniture is investigated.

在这篇论文里，我们将探讨室内的金属家俱在超宽频(Ultra-Wide Band，UWB)通讯上对位元错误率的影响。

This reduces the impact of a short circuit and assures that the bus does not conduct current through the aircraft. A Manchester code is used to present both clock and data on the same wire pair and to eliminate any DC component in the signal (which cannot pass the transformers). The bit rate is 1.0 megabit per second (1 bit = 1 μs).

该结构可以削弱短路对总线的影响并保证总线不会传导在航空器中流转的电流。1553总线用曼彻斯特码表示导线对上的时钟信号和数据信号，这可以去除信号中的直流成分，因为直流成分不能通过变压器。1553总线的波特率是1兆位每秒，即每微秒传输一位信号。

Phencynonate replace the pyrrole N-bit H chemical shift on the issue of the impact.

苯环取代对吡咯N位H上化学位移的影响等问题。

In order to analyzes the soil deformation mechanism under the impact load of the step-bit, the finite element model of impact and displacement drilling with down the hole hammer is established on the basis of adopting Drucker-Pager yield criterion, taking soil as DP materials and simulating the drilling process by applying the impact load on soils.

为了分析阶梯钻头冲击挤密作用下土体的变形机理，将土体视为DP材料，服从Drucker-Prager屈服准则，通过钻具与土体之间的接触以及施加冲击载荷来模拟钻进过程，建立了潜孔锤冲击挤密钻进的有限元模型。

In order to raise drilling speed of the non saline dome wells in Kenkiyak Oilfield, the relationship between rake angles of the cutter, profile of the bit, which have effect on cutting depth and impact-resistant of PDC bit cutters, and cutting efficiency is studied respectively using finite element analysis according to rock properties of the research area. The structure of the PDC bit is then optimized by using the research result.

为提高肯吉亚克油田非盐丘井钻井速度，根据地层岩石力学参数评价结果，利用有限元方法对影响PDC钻头攻击性和抗冲击性的齿前角、冠部形状等结构参数与破岩效果之间的关系进行了研究，并对PDC钻头的结构进行了优化设计。
