刀尖

I want to look at the mowers, and wonder why fatness, elderliness, and black trousers should inevitably wear a new straw hat of the boater variety, move in stiff jerks, shove the end of the scythe-strokes with a certain violence, and win my hearty disapproval, as contrasted with young long thinness, bright blue cotton trousers, a bare black head, and a pretty lifting movement at the end of the scythe-stroke.

我想看割草人，想知道为什么这个胖子、长者和黑裤子竟非要戴一顶硬边的新草帽，而且动作不灵活，颇废气力地用长镰的刀尖割草；而年轻人又高又瘦，身着天蓝色棉布裤子，一头黑发，不戴草帽，用长镰割草时，刀尖优美地向上一提，使我在对照之下对年长者产生由衷的不赞同。

He lunged towards his messmates in turn a thick slice of bread, impaled on his knife

Let the blade fall to the front to a position near the horizontal, elbow well away from the body, forearm and saber forming one straight line, edge of the blade to the right, point at height of adversary's breast, at the same time placing the left hand, closed, 6 inches in front of the belt buckle to simulate the position of the bridle hand.

让刀下落至前面接近水平，肘离开身体，前臂和军刀形成一条直线，刀刃向右，刀尖指向敌人胸前。同时将左手紧握，置于皮带扣前6 寸的位置，模仿握缰绳。

Wearing the broad-brimmed Breton hat that was her hallmark, her scissors hanging from a ribbon around her neck, and her four fingers held firmly together in spite of severe arthritis, she would feel for defects. Working directly on the model, she often picked a apart with the point of her scissors, complaining that it was unwearable.

头戴宽边布雷顿帽是她的标记，她的剪刀悬挂在围绕于她颈项的缎带上，同时她不顾严重的关节炎而把四个手指紧紧攥在一起，她寻找瑕疵，她直接在模特上工作，经常用剪刀尖指出其毛病，抱怨它不合身。

The implanted thermocouple cannot measure the workpiece temperature directly because the thermocouple junction is away from the workpiece. Infrared radiation pyrometer can response fast.

也不宜采用在刀具内埋置人工热电偶的方法，因为埋置热电偶时，热电偶接点与刀尖多少有些距离，而刀尖处的温度梯度较大，因而不能直接测量工件的温度。

The system measured the tool angle, corner radius and cutting edge of tools, against the tool wear of numerical control machine and machining center.
