An optimized design method of the ratcher mechanism in the multi-step belt conveyer with intermittent movement is presented.

摘要提出了一种多步距间歇运动的带式输送机棘轮机构的优化设计方法，并给出了设计实例。

Over the years various kinds of both bench and stand-mounted countershafts were available: one model of bench countershaft featured a four-step final-drive pulley with a "fast-and-loose" drive from the motor (which gave the effect of a clutch) whist the other dispensed with this arrangement and was driven directly from the motor by what the makers described as a " special joined V-belt ".

多年来各种都替补和备用安装countershafts有：一种模式的板凳副轴功能的四步最后驱动滑轮的"快速和宽松"的电机驱动器惠其他免除这一安排，并直接驱动电机的制造商所形容为"特别加入V带"。

At step 2 a black crosshair with a circle appears in the middle of the picture: this represents the pivot point for the rotation.

在第2步，带圆形的黑色十字线出现在图片的中心：这代表了旋转的枢纽点。

The PTK crus prosthesis and that with silicone liner locked have different effects on suspension under different step speed.

PTK小腿假肢和带锁硅胶小腿假肢在不同的步速下行走对假肢的悬吊可产生不同程度的影响。

In this paper, one spacer- armed analogue of a disaccharide SM_3 was synthesized for the first time via multi-step synthetic method.

本文经过11步反应，首次合成了带连接臂的SM_3寡糖链，为今后合成具有更高分子量的糖基缀合物并研究其抗肿瘤免疫原性奠定了基础。

I work as a director, commercials, TV shows, music videos and recently my first feature film.

我是一名导演，做商业活动，电视节目，音乐录影带，还有最近我的第一步电影。

I was loath to spend our last Shot too hastily; so I call'd my Servant, not my Man Friday, for he was better employ'd; for with the greatest Dexterity imaginable, he had charg'd my Fusee, and his own, while we were engag'd; but as I said, I call'd my other Man, and giving him a Horn of Powder, I bad him lay a Train, all along the Piece of Timber, and let it be a large Train; he did so, and had but just Time to get away, when the Wolves came up to it, and some were got up upon it; when I snapping an uncharg'd Pistol, close to the Powder, set it on fire; those that were upon the Timber were scorcht with it, and six or seven of them fell, or rather jump'd in among us, with the Force and Fright of the Fire; we dispatch'd these in an Instant, and the rest were so frighted with the Light, which the Night, for it was now very near Dark, made more terrible, that they drew back a little.

我不愿匆匆放完最后一排枪，就叫来了自己的仆人。我没有叫星期五，而是叫了我新雇的那个水手。星期五有更重要的任务要完成。在我们开火的时候，他以惊人的速度给我和他自己的枪装弹药。所以我说，我叫的是新雇的仆人。我给了他一角火药，命令他沿着那根长木头把火药撒下去，撒成一条宽宽长长的火药线。他照着办了。他刚转身回来，狼群就冲了过来，有几只甚至已冲上了那根长木。我立即抓起一支没有放过的手枪，贴近火药线开了一枪，使火药燃烧起来。冲上木料的几只狼给烧伤了；其中有六、七只由于火光的威力和惊恐，竟连跌带跳地落入我们中间。我们立即把它们解决了。其他的狼被火光吓得半死，加上这时天已黑下来，火光看起来就更可怕了，这才使那些狼后退了几步。

Vertical alignment system is the transmission ratio of stepmotor, it does this by embossing drum gear-driven version of drum rotation, you actually change the version of the rollers and publishes materials for the relative position between the longitudinal.

纵向套准编制拔取的是矮传不静比的步进电机，它堵住压印滚筒齿轮带不静版滚筒转不静，本质上是保持版滚筒与承印质料之间纵向的不绝差场所。

The form of its locomotion is: first, drive shaft inconjunction with the knife rest going down vertically in a certaindistance, then the magnetic stepping motor works, then the gearwheel group revolving with the shaft and the knife rest. Afterrevolving a circle, the air pressure vat decompresses, then, theshaft and the knife rest resets in the result of the spring.

其运动形式是：通过气压缸将传动轴和刀架打下一个固定距离，然后步进电机开始工作，通过带轮组带动传动轴和刀架作旋转运动，旋转360度后气压缸开始减压，复位弹簧使主轴和刀架复位。

I took a few steps forward, contemplated closing my eyes in-case it was a God-awful effort, and hit it as hard as I could.

我带了几步向前，设想我的眼睛闭幕的情况下，它是一个上帝的可怕的努力，并触及它像我可以。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
