Utilized the correlative knowledge of mathematics and theoretical mechanics, the movement measure of the rolling forming of rectangle ring have been studied that based on the ring rolling theory. And the corresponding geometrical models and mathematical models have been established. It was revealed the variation law of ring in the cold rolling process.With the rolling processing, the inside and outside diameters of ring gradually increased with the cures similarly hyperbolic and the augment speed of the inside diameter was obviously larger than the augment speed of the outside diameter. With the rolling processing, the displacement, speed and acceleration of the ring centre gradually increased in the feeding direction in the horizontal and vertical ring rolling mill. With the rolling processing, the moment of inertia which ring reeled its centre and the whirligig of ring gradually increased. It caused the rotary speed gradually decreased. And it was benefit to decrease the circle tolerance and improve the precision of final molding.

本文基于环件轧制理论，运用相关的数学知识和理论力学知识，研究了冷轧过程中矩形截面环件轧制成形的运动测量，并建立相关的几何模型和数学模型，揭示了冷轧过程中环件的变化规律：随着轧制过程的进行，环件的内外径随类似于双曲线的曲线逐渐增大，且环件内径增大速度大于外径增大速度；在卧式轧环机和立式轧环机下，随着轧制过程的进行，环件中心的位移、速度及加速度不断增大；随着轧制过程的进行，环件绕其中心的转动惯量不断增大，导致环件的转速不断减小，这样有利于环件的整圆和最终成形环件的精度。

Part Ⅰ: Since the study about breaking onset criteria base on the downward acceleration or on the wave slope shows great discrepancy, the models that estimating breaking probability and whitecap coverage according to these two criteria are problematic.

第一部分：因所采用的动力学或波陡判据的不确定性和海浪谱四阶矩的难以确定，现已提出的关于风浪破碎率和白浪覆盖率的统计模式有一定的不确定性。

The background of social transition, which is the division of social structure, the acceleration of social mobility, and the disticntion of social differiation, not only leads to the wideness of the interest gap, but also brings about both the complication of social relation and the intensification of conflicts among the different interest groups.

在社会转型大背景下，随着我国社会结构分化的加速，带来了社会流动的频仍和社会分层的明显，也带来了利益差距的扩大、社会关系的复杂化和利益矛盾冲突的加剧。

According to Newton's law, all objects fall to Earth at a rate of acceleration of 9.8 meter per sec2 (32 ft/sec2), which in the case of our wing, is opposed or slowed down by the aerodynamic forces.

根据牛顿定理，所有的物体皆以每秒9.8米(32英0/秒)的加速度的比率下降到地球。而我们伞翼情况，则是被空气动力学的力量抵消或者减速。

It is revealed that in comparison of the rigid wing case, the wing deformation acceleration in the flexible wing case leads to the added inertial effect which causes a lot of change in instantaneous aerodynamic performance of the wing.

由柔性翼和刚性翼的结果比较发现，附加惯性效应是动态变形影响气动性能的主要原因，变形加速率决定了瞬时气动性能改变量的大小，相比之下，动态变形对气动性能时均值的影响则弱得多。

The F-15's maneuverability and acceleration are based on high engine thrust-to-weight ratio and low wing loading.

F-15具有高度的机动性和加速性能，其推重比极高，超过1，而单位翼载荷则很低。

More rounded wings produce more lift toward the wingtip and are particularly effective for birds that fly at slow speeds or need high levels of acceleration.

更圆的翅膀产生更多解除对wingtip和特别有效，为鸟类飞行速度变慢，，或需要高水平的加速度。

With an inexpensive compact car, there is no middle ground in acceleration: it's either zippy or it's a dog.

一辆廉宜的紧凑型汽车，在加速方面，是没有中间派的：一是身手敏捷的，否则的只是有一头小狗的表现。

Driving Impressions 驾驶印象 With an inexpensive compact car, there is no middle ground in acceleration: it's either zippy or it's a dog.

一辆廉宜的紧凑型汽车，在加速方面，是没有中间派的：一是身手敏捷的，否则的只是有一头小狗的表现。
