轧制

The discovery and verification of energy coupling mechanism entitled as "rolling" and "wobbling" naturally produced among earth and sun supplied us a powerful evidence for ubiquity of repulsion at the scale of natural inter-planet, and then demonstrate a natural macro-phenomenon of counterattraction existing in interstellar matter since Newton′s great discovery of gravitation.

日—地间天然形成的能量相耦合的"轧制"式和"摇摆"式物理机制的发现与证实，为自然界星际尺度间的斥力作用普遍存在提供了有力的证据。这是自牛顿发现万有引力之后，首次对宇宙中星际间存在的"反引力"作用这一宏观自然现象的揭示。

And using the DEFORM software to carry on the simulation to the rolling process.

并采用DEFORM软件对轧制过程进行了模拟。

The key of new process focuses on 2 points:one is lower cold deformation ratio and another is 2nd annealing at lower temperature(250 , 30 min). Relevant comparison experiments show that new...

工艺的关键在于在相对低的最后一次变形率(ε=30%)条件下，进行低温二次退火(250℃/30min)，用该工艺轧制所得银带在自然时效时力学性能十分稳定。

The densification rate of the surface layer of the preforms was the most fast.

在轧制过程中，轧件上表面的致密化速度最快。

It is established the evaluation method of annealing detergence for copper rolling oil by simulating industrial program with thermogravimetric analyzer.

用热重分析仪模拟工业退火程序，建立了铜轧制油退火清净性的评价方法。

For example, the roll elastic deformation breaks the statically determinate condition of roll system in duo mill, and this is the main reason of bearing longevity shortening and burning accident; in aluminium foil four-high mill roll system with a 1 mm gap, the ideal position kept by a 3 mm offset is out of effect, some phenomenon such as chock horizontal vibration, gyroscopic effect and micro dimensional dynamic cross happen in fact rolling process, abnormal super and partial load resulted by these is the main reason of the end thrust bearing accident; the thermal deformation of mill roll system accompanying the temperature raising not only changes the roller track age of rolling bearing, but also results a micro dimensional slow dynamic inverse cross that counteracts the gyroscopic effect in a degree.

如二辊高刚度轧机轧辊的弹性弯曲微尺度行为，破坏了辊系机构杆系的静定条件，成为轧机轴承短寿烧损的主要根源；铝箔四辊轧机只具有1mm的有隙辊系，凭借设置3mm偏移距和轧制力平衡产生的水平力以保持轧辊理想定位失去效用，却发生轴承座水平振动现象、陀螺效应和动态交叉微尺度行为，成为止推滚动轴承异常超偏载导致短寿烧损的主要根源；轧机辊系的伴随升温产生的热变形，不仅改变了滚动轴承滚道轮廓，还引起运动副内慢变动态反交叉微尺度行为，抵消陀螺效应的部分动态交叉角度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
