查询词典 tip of drill

The results showed that the performance of the drill pipe joints was in line with standard and the main reason was that the making up torque was inadequate.Drill pipe joints in underground unrestrained tightening-up caused the drill pipe joints to bear the excessive load more than their anti-torque yield strength.

结果表明：钻杆接头的各项性能指标均符合标准规定，失效的主要原因是上扣扭矩不足，钻杆接头在井下无节制旋紧，致使钻杆在井下的自上扣扭矩超过了钻杆接头的实际抗扭屈服强度。

This paper analyses that tip angle of drill bit influences on cutting capability and life of twist drill, when the material and shape of work piece is different.

分析了工件材料、形状不同时，钻尖顶角的大小对麻花钻切削性能及寿命的影响，介绍了麻花钻的钻尖顶角的选择。

The so-called cutter location point, the flat end mill tool axis refers to the point of intersection with the bottom tool; for ball-end milling is the ball part of the core; for tools is the tip; the drill is the drill point; for wire electrode cutting machine, it means that the axis line of the electrode surface and the focus of parts.

所谓刀位点，对于平底立铣刀是指刀具轴线与刀具底面的交点；对于球头铣刀是指球头部分的球心；对于车刀是指刀尖；对于钻头是指钻尖；对于线电极切割机床，则是指线电极轴心与零件面的焦点。

Leaves in opposite pairs, thin coriaceous, oblong, or phi needle-shaped, long 6-14 cm, the top length gradually sharp, pointed or slightly blunt wedge base, edges wavy or light wavy; petiole length 8-15 mm; stipule wide and triangular, was born in the Ministry of young vine at the top of drill-like long-tip , was born in the old vine, 3-6 mm long, the top regular convex tip.

叶对生，薄革质，矩圆形或披针形，长6—14厘米，顶端长渐尖，基部楔尖或略钝，边缘波状或浅波状；叶柄长8—15毫米；托叶宽三角形，生于幼枝上部的顶端钻状长尖，生于老枝上的长3—6毫米，顶端常凸尖。

This is the same as the "batching" tip from the work section above (as is the previous tip, and the next tip).

这和上面工作部分的批量处理的道理是一样的（这和前面的建议以及后面的建议是一致的）。

The detailed comparisons between the higher—order near tip solution and the well—known modified Prandtl field are also given in this paper.For the compressible materials, in order to satisfy the higher-order compatibility equation of the rate of deformation in the centered fan sector, which is a quite difficult problem unresolved in the previous studies, a particular term must be added to the expansions of the stress components in the regular logarithmic power series adopted by many researchers before. A higher-order near tip field with tangential velocity jump ahead of the crack tip is derived first, of which the dominant terms are the solution widely accepted.

对可压缩材料，本文首先采用非规则的对数幂级数渐近展开方法，克服了过去研究中存在的中心扇形区变形率协调方程的高次渐近式不能被满足的困难，并得到了一个切向速度在裂尖前方存在间断的高阶渐近解，该解的主项就是目前被广泛接受的关于可压缩材料的尖端场解。

From these result of the experiment, the dynamic modeling can be simulated effectively, when the move speed of tip is faster the shear force in the tip is bigger. In the lithography process the motion of tip influence by the pile up, it leads to the serration surface of the groove, is like the surface of actual material of the cutting process.

由加工成形与磨耗结果回馈，可有效做探针动态建模，并模拟出，当探针移动的速度越快时，针尖所承受的剪应力越大，并且在蚀刻过程中，针尖受表面堆积物的影响，导致沟槽表面类似锯齿形的蚀刻表面与实际加工之情形相似。

The findings indicate that, on the whole, the pattern of load transfer curves of adfreezing stress on a steel pipe pile stem and that of resistance stress on the pile tip are parabola and straight line, respectively; Due to the rheology effect, to different extent, adfreezing stress on the pile stem and resistance stress on the pile tip vary with time and relative displacement of pile-soil, respectively, and the settlement of pile tip varies with time tempestuously within 5 hours of loading, and then approximates to stability.

结果表明：模型钢管桩桩侧冻结力荷载传递函数曲线及桩端阻力荷载传递函数曲线其线状大致分别程抛物线及直线；由于流变效应的影响，桩侧冻结应力及端阻应力随时间有不同程度的变化；桩土相对位移和桩端下沉量开始5h内随时间变化较大，但加载5h后逐渐向稳定方向发展。

Looking to bounce back from defeat against Cesena last weekend, the Calabrian boss will be sticking to his tried and tested 4-3-3, with Lopez and Sedivic joined up front in Giampaolo's absence by either Nanni or Plasmati.

鉴于上周末对切塞纳的比赛中反败为胜，这支南方球队将会更坚持其一贯而有效的4-3-3阵型，洛佩斯和塞德维奇将取代受伤缺席的詹保罗，和纳尼或者帕斯马蒂中的一个搭档锋线。
