棘轮

Reuleaux defined six basic mechanical components: the link, the wheel, the cam, the screw, the ratchet, and the belt.

他 为我们提供了这样一个概念kinematic pair 其形状和互动定式运动之间传递元素在mechanism.reuleaux确定了六个基本的机械部件：的联系，该轮，凸轮，螺丝，棘轮，带。

The set includes: powerful ratcheting handle, comfortable grip, chrome vanadium steel keys with black oxide coating for hardness.

该套装包括：强大的棘轮手柄，舒适的抓地力，铬钒为黑色氧化膜硬度钢的关键。

Ratchet reverses direction with convenient switch.

棘轮扭转方便开关的方向。

As the piston descended, a ratchet engaged the piston rod and engine shaft and thus power was transmitted

当活塞下行时，棘轮连接活塞杆和发动机轴，因此将功率输送出去。

Alternatively,有性生殖 may allow for the ' ratcheting ' of evolutionary speed as one clade competes with another for a limited resource .

或者，有性生殖可能象'棘轮'那样控制了进化发展的速度，因为一个进化枝会和另一个竞争有限的资源。

Rich countries, where food is a small part of total consumption, have less to worry about, although they should beware the ratchet effect as food importers increase subsidies and food producers tax exports, driving up world market prices still further.

对于食品在消费总开支中只占一小部分的富裕国家而言，需要担心的问题要少一些，但他们应该意识到，食品进口过增加补贴和食品生产国征收出口关税会带来棘轮效应，进一步抬高世界食品价格。

The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。

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。
