转速

Torque rheometer with an internal mixer is commenly applied to study the property of PVC in polymer laboratory. Compounding temperature、rotor speed、and totalized torque are three main influence factors to affect the fusion of PVC in a torque rheometer.

力矩流变仪(To-rque Rheometer)配备内部混合器是一般高分子加工实验室常用的PVC混练仪器，而此仪器影响PVC熔合最主要的混练因素为混练温度、转轴转速及力矩总和(Totalized Torque；简称TTQ)，本文应用一个2的3次方因次实验设计法来判定上述三个混练因素对PVC熔合之影响程度。

The expected viscosities of polyamide solutions and the corresponding spindles at the specified speeds are shown below

The gas turbine engine windmilling is a state that when the engine doesn t work,the rotors temporarily operate at a sub-steady rotating speed due to the airflow ram and the co-work of aerodynamics,rotor inertia and drag torque.

由于很多燃气涡轮发动机都缺乏计算风车特性必需的低转速状态的部件特性，给计算发动机风车状态的特性带来了很大的困难。

The sugarcane windrowing distance and angle increase with the increasing of the rotational speed.

随着转速的增加，甘蔗铺放距离和铺放夹角都呈增大趋势。

The experiments of sugarcane transportation and windrowing quality indicate that rotational speed and forward speed have not obviously effects on the transportation success rate.

甘蔗的输送质量和铺放质量试验研究表明，转速、前进速度对甘蔗输送通过率没有明显影响，通过率均保持95%以上水平，甘蔗均能够可靠进行输送。

The spindle selects enclosed rolling bearing for supporting; vertical and horizontal drag board are adopted with enclosed rolling rod drive; body guide ways are casted with abrasion-resistance iron quenched with super frequency and milled precisely, and all these contribute to a long-term processing precision and a long lifespan; 5.5KW motor serves as the main motor contribute to a stronger turning capacity and larger rotary speed range; Workpiece clamping is are adopted withed with spring collet, it can also be equipped with hydraulic chuck, four-spindle oil cylinder, pneumatic, hydraulic tail stock.

Rev rate is very important, but not in the manner most bowlers evaluate it.

转速很重要，但它并不是以时下多数球员所评估的方式来展现。

Bowlers have tools to work within…rev rate is just one of them.

球员需要很多工具来作调整…转速也只是其中的一环而已。

The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

本文主要是以DEFORMTM有限元素软体模拟U型钢片连续道次成型与单一道次成型以确认单一道次模拟的是否可取代连续道次模拟之研究。因DEFORMTM 软体对於网格元素上的限制故使用较短素材120mm通过所有的成型站以模拟工厂实际连续成形方法。辊轮间隙固定为0 3mm；辊轮转速为20 rad/sec；弯曲角度的方法为将成型角度平均除以成型站数。有三种辊轮成型方式被选择分别为6站，9站，与12站。在模拟的过程中有两种现象会产生 Case A，素材通过单一成型站。Case B，素材会通过两个成型站。因为在模拟过程中素材的两端会有拉应力与扭力。Case B的模拟比Case A像实际的制程，并计算应力与应变在U型断面的Tip部中可发现Case A比Case B低约15%。从Case B的每站的结果可以得知，12站的成型应力最小，9站次之，6站最后。

Although it is customary to put these brushes into a hand-held electric drill motor or a speed controlled air drill, they might also be used in drill presses.

通常扭丝型刷子被用于手提便携式电钻或转速一定的风钻，同时它也可在钻床上使用。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
