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。

This can be kind hard to do when the draws are resting on slabby stuff, as the rope is interfered with by the rock. It has a distinct advantage that you can easily "grab" the draw if you start to slip, and that you can use the pull on the draw to bring up slack out of the rope.

这在斜板地形较不顺手，因为快扣靠在岩壁，绳子会被岩壁妨碍到；不过，好处是当你有点要滑动时可以&抓住&快扣，且顺势带出贴紧岩壁的绳子。

The DNG structure unit is composed of square split ring resonator and strip wire. The modified NRW method is used to extract the equivalent permittivity, permeability, and refractive index from the scattering parameters of the two-port waveguide with DNG structure. At the designed operating frequency, the refractive index approximates zero, which makes the nondirective electromagnetic wave tend to approximate plane wave along the normal direction of the superstrate and congregate the radiation energy.

以方形的SRR环和金属条带构成双负媒质结构单元，使用修正的NRW方法，通过放置双负媒质结构的二端口波导的散射参数，提取了等效的介电常数、磁导率和折射率，在所设计的工作加热板频率，折射率接近于0，可以将原本发散的电磁波整理成趋近于覆层面法线方向的近似平面波，起到能量汇聚的功能。

For example, if "I love you" is not said wholeheartedly, a sour candy will be shown on the display board.

如果情人的&我爱你&说得不够诚恳，显示板就会滚出带酸味的糖果。

The function and adjustment of beveling machine in the production line is studied mainly in term of the floating copy of planners and the strip position cotrol via guide and vertical rolls.

阐述刨边机在高频焊管生产线中的应用以及调整问题，主要从刨刀的浮动仿形和通过导板以及立辊控制带钢的位置两方面进行分析。

His wrists and ankles are cuffed to the board and his head is rigidly held in place by a strap around his neck and a helmet on his head.

他的手腕和足踝都被拷在板上，而他的头部被一跟环绕着他脖子的带子僵硬的吊了起来，并且他的头上还带着一个头盔。

This method of deposition offers the possibility of entrapping a large and well-known amount of enzyme into the clay film.

Indeed, some plateaued players have probably advanced as far as they can given these faults (e.g. they have maximized what''s possible when standing wrong with a funny grip).

事实上有些选手带着这些错误已经练到不能再强了（例如他们用可笑的抓板已经最大极限地发挥了可能性）。

I will endeavour to find you some assistance.
