1将安装接头吊置于安装部位，并充分调整接头法兰连接螺孔与安装管道法兰连接螺孔全部对齐，中心轴线保持同轴一致。

By means of using a disc cutter with a concave end instead of traditional ball-ended or flat-ended ones,and adjusting the cutter axis to move relatively to the component being machined according to some special rules,the envelop formed by the trace of the tool-nose in each pass and the required surface have the same derivatives up to the second order in the plane normal to the feeding direction.

采用二阶密切曲率法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1阶？

The measurement of time first originated and is based on the earth's motion upon its axis. One of the smallest cycles, or time factors, which repeats regularly in things that are very active and have a high vibration, is the four-minute cycle.

时间的度量基于地球围绕其轴线的自转，四分钟循环是最小的循环之一，是事物不断重复自身的最活跃的一种频率。

The effect of the friction between rolls and ring can be ignored and the effect of the spread velocity of rolling on the deformation of ring is illustrated.

通过模拟分析比较，揭示出了环件轧制过程中的金属流动规律：轧制时，环件外侧的变形最大，厚向中心部位变形最小，内侧的变形程度介于中间；环件内外环面的压应力分布和变化规律：在垂直于环件轴线的对称面上，压应力分布近似对称状态，而且在对称面上的应力最大，往端面方向开始减小；指出了环件轧制中轧辊与环件摩擦对环件成形的影响：对于环件的宽展变形，摩擦的影响很小，可以忽略；分析了环件进给速度对环件成形的影响并阐述了环件厚向中心部位凹陷产生的原因，提出防止凹陷的措施：在轧制时，尽量使用快的进给速度有利于防止端面凹陷的产生；研究了导向辊位置对环件成形以及轧辊受力的影响：导向辊的位置对环件的宽展变形影响很小，但对轧辊的受力影响较大，当导向辊的中心位置位于毛坯初始中心位置之上时，驱动辊和芯辊的受力相对较小，这是导向辊导向时优先考虑的位置。

The gimbal ring and drive axis is impossible to coincide with the centre axis of gyroscope completely during the assembly process.

摘要在动力调谐陀螺的装配过程中陀螺和平衡环的中心轴总是不可能完全与驱动轴轴线重合，因此存在一定的安装倾斜角。

Aim and Methods\ Three methods are analysed and compared for measuring the lateral deflection of gun bore axis from firing plane and the deviation of the sight line from the barrel axis, according to the results measured in practice. Results\ The tested data show that this new method is accurate.

引 言在多次火炮总装测量检查中，我们发现用炮口瞄准仪测量&炮膛轴线偏离射面的偏离角&与&瞄准线偏移&和用经纬仪、炮口坐标尺测量这两个项目有一定的差别。

The helix angle on the worm is generally quite large, and that on the gear very small.

蜗杆上的齿斜角度通常很大，而蜗轮上的则极小，因此习惯常规定蜗杆的导角，那就是蜗杆齿斜角的余角；也规定了蜗轮上的齿斜角，该两角之和就等于90度的轴线交角。

The invention also relates to a device comprising at least one one-way detection unit constituted by a pressure sensor disposed outside the cladding and connected to the inside the cladding via a horn-shaped duct which slopes relative to the axis of the cladding, which has its mouth opening out in the cladding, and which has its tip connected to the pressure sensor.

还公开了一种装置，包括由压力传感器（14，15）构成的单向探测单元，压力传感器设在包层（11）的外面，并通过牛角形的导管（12，13）与包层（11）内部连接，导管相对于包层（11）的轴线倾斜，并有开口进入包层（11），导管的顶部与压力传感器（14，15）连接。

It is most likely that only a part of the karst caves could be detected if the boundary of the karsts cave has a certain horizontal extension respectively to measurement layout, but the interface of the karsts caves is not completely smooth plane, and its normal direction is not perpendicular to the tunnel axis.

如果溶洞的边界相对于TSP测量布线有一定的横向延伸性，其边界面不一定是完全平滑的表面，但其法线方向与隧道轴线不完全垂直，这类溶洞有可能被部分探测，但探测精度还与溶洞界面两侧的波阻抗差、对地下水的探测、操作人员的数据采集经验和数据处理水平等有关。

It is most likely that only a part of the karst caves could be detected if the boundary of the karsts cave has a certain horizontal extension respectively to measurement layout, but the interface of the karsts caves is not completely smooth plane, and its normal direction is not perpendicular to the tunnel axis. However, the precision of the cave detection is related to interface wave impedance difference of the karst caves, groundwater detection, operator's data acquisition experience and data processing level and so on.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
