查询词典 back-pedal

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.

数值模拟结果表明，(1)在涡轮达到工作转速时，在分级区域形成了一个与涡轮旋转方向相反的局部回流涡，它使得分离出来的细粒重又被带回分级轮外边缘，从而严重影响分级机的分级效率；(2)粉尘粒子在涡轮低速运动情况下，基本上能跟随气体运动，但随着转速加大，两相之间出现了明显的速度滑移现象；(3)分级机工作时的风量也是一个比较重要的操作参数，它可以直接影响到分级机内腔流场的稳定性，风量越大，流场越稳定；(4)同直叶片形状相比较，带后弯导板的叶片，有利于改善流场的稳定性，流场容易形成整体流，对提高分级效率和分级精度都非常有利；(5)粒子轨迹线在涡轮转速较高时十分复杂，有的出现了反复的弹跳现象，大颗粒不能通过分级区域而从进口返流了，只有细小的颗粒才从出口处流出；(6)涡轮转速加大时，粒子的径向、轴向和切向速率出现了明显的类似于正弦波的脉动现象，颗粒越小，脉动程度越为剧烈。

这个词最早的来源是古法语单词retirer ，由在此意指&向后&的前缀re-及意为&拉&的动词 tiver 合在一起组成，意为&撤回或退回&。

杜昭，蔡文，黄德征（广西医科大学第六附属医院手外科，广西玉林537000）摘要：目的探讨手部创伤组织缺损显微外科修复方法及其效果。方法采用食指背侧岛状皮瓣、缝接指神经的背侧支指动脉逆行岛状皮瓣、邻指皮瓣、掌背动脉逆行岛状皮瓣和前臂骨间后动脉逆行皮瓣、髂腹股沟皮瓣、髂骨皮瓣及胸脐皮瓣转位修复手部创伤组织缺损197 例。

When the parameter matching of the wheel location is improper, namely, the matching between the wheel toe-in and the wheel camber angle is ill-suited, abrasion of the two wheels of the same steering axle is inside or outside simultaneously, because of wheels sideslip. However, when double-front-axle steering system failure take place, abrasion of the two wheels of the same steering axle is in the same side, and that, tyre abrasion direction of front and back steering axles is rightabout. That is to say, if tyre abrasion of front steering axle lie in the left side, tyre abrasion of back steering axle lie in the right side to a certainty, which is the rule of tyre abrasion of double-front-axle steering automobile.

当定位参数匹配不当时，同一转向轴上左右车轮的磨损部位都在内侧或外侧，原因是左右车轮在滚动的同时还要产生相向或反向侧滑；而双前轴转向汽车前、后转向轴引导汽车转向方向不一致时，同一转向轴左、右车轮的磨损部位都在同一侧，而且前、后转向轴上的车轮偏磨损方向正好相反，即如果前转向轴左、右车轮磨损部位在左侧或右侧，那么后转向轴左、右车轮磨损部位就在右侧或左侧，这是双前轴转向汽车特有的轮胎磨损规律。

I do not have such feeling all along, and she walks together, many person uses another the eye resembling to be looking at me , she is indeed very ugly, with she together to such an extent even my feeling is extremely not natural,as if others goes to a piece in doubting that how I can follow her, I have also felt self at the same time as if advantageous many, but her bothers me readjusting oneself to a certain extent , tying up to death rottenly fight , the time complaining that I give her unceasingly is very few, That the chance shirking a dinner party for I design the consummate excuse goes to accompany her , the once to gamble , loses almost I am willing to at 00:100:100, is to walk for 200 meters with the back towards her , she kisses my once , God right away if I have won, I be willing to the back will stop to 10 meters!

While trying to get a grasp of the septile aspect, I went back to John Addey (1920 1982), a key voice in bringing Pythagorean understanding of numbers into modern astrology. He wrote Harmonics in Astrology in 1976; it is now back in print after many years. He writes that the number seven (and the 7th harmonic)"is a difficult number to pin down" and "somewhat elusive to interpret."
