On his head Agamemnon set a helmet, with a peak before and behind, and four plumes of horse-hair that nodded menacingly above it; then he grasped two redoubtable bronze-shod spears, and the gleam of his armour shot from him as a flame into the firmament, while Juno and Minerva thundered in honour of the king of rich Mycene.

最后，他抓起两校粗长的枪矛，挑着锋快的铜尖，铜刃闪着耀眼的寒光，射向苍茫的蓝天。见此景状，赫拉和雅典娜投出一个响雷，嘉赏来自金宝之地的王者，慕凯奈的主宰。

The features of involute gear profile are mapping analyzed, the principle and method of on machine measuring the longitudinal form error of bull gear s with the rack probe is introduced, the data evaluation model of longitudinal form error is established, and a measuring example is given.

对渐开线齿轮廓面特性进行了映射分析，介绍了齿条刃边测头在机测量大型齿轮齿向误差的基本原理及测量方案，建立了齿向误差的数据评定模型，并给出了测量实

Once that was done, he set to the real work: with hand drills, handsaws (their teeth rubbed, to run more smoothly, with a candle end), his bevelled-edge chisel and his wide, heavy, trusty Number 7 plane, which he used for everything.

这些一旦完成，就开始真正的木工活了：用的是手钻、手锯（为了拉起来顺手，锯齿是用蜡烛头磨过的），还有他的斜刃凿，还有又宽又沉的7号刨子，这个他用起来得心应手，做什么活时都用的到。

这道工序完成后，他才真正开工，用的是手摇钻、手锯（为更好聚裁，锯齿都用蜡烛头涂抹过）、他的斜刃凿以及好使的宽大厚重的7号刨刀，不管做什么都用得到它。

According to that, the analyses are made on the internal force, the pulling force, the bending moment and twisting moment which make the chip break.

开发出由凹曲面、凸曲面和曲线刃组成的新型复杂三维断屑槽型，可满足小背吃刀量和小进给量的精加工要求。

The cutting edge inclination and the clearance angle is 0°and 3°.

而刃倾角和后角分别为0°和3°。

So one more drill point geometric parameter is needed, such as heel clearance angle, chisel edge clearance angle.

为了获得唯一的后刀面廓形，必须增加一个辅助参数。可供选择的补充参数有尾隙角、横刃后角、周边后角、切深后角等。

可供选择的补充参数有尾隙角、横刃后角、周边后角、切深后角等。

This paper also makes a experimental study of the regularities of the outstripping machining in aspects of machine tool, cutting tool, cutting conditions and so on, and points out that the outstripping phenomenon occurs on the following conditions: the machine tool with high precision, the PCD cutting tool with small clearance and lay angle, the small installation angle, the small feed rate and the cutting lubricant with good properties, and that the cutting speed and the depth of cut have no effects on the outstripping machining.

本文还从机床、刀具和切削条件等方面对超越性加工的规律进行了实验研究，指出超越性加工现象是在如下条件下产生的：较高精度的机床、后角和刃磨纹理角较小的PCD刀具、较小的安装角和较小的进给量以及冷却润滑性能良好的切削液，而切削速度和切削深度对超越性加工几乎没有影响。

Card sets of connections, in China only developed in recent years, it's connecting and sealing principle is that when the nut tightened up, the card sets under pressure to edge into the tube outer wall of the Department of bite, card sets and outside the cone with the joint under pressure All cone density in vivo, which can reliably prevent the leakage.

卡套连接，在我国近年才发展起来，它的连接和密封原理是，当旋紧螺母时，卡套受到压力，使其刃部咬入管子外壁，卡套外锥面又在压力下与接头体内锥面密合，因而能够可靠地防止泄漏。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.
