有变化力的

In general, the forces acting on a body vary in both magnitude and direction, resulting in complicated type of nonuniformly accelerated motion, which cannot be investigated in an elementary physics course.

通常， 作用在物体上的力在大小和方向上都有变化，结果产生了一种复杂的非匀加速运动，这种运动不可能在初等物理教程中加以研究。

As the track space increasing, the holding power which flexible holding parts act on sugarcane is dropping off. As the canvas layers and length of flexible holding part increasing, the track space is also increased when flexible holding parts act on sugarcane same holding power. As the length of flexible holding part increasing, the rate of slope of holding power following the track space to change would be decreased, so holding power would vary slowly. The holding power has a better linear relationship with the track space. Holding sugarcane stalk on knot or not on knot, sugarcane stalk having leaves or without leaves, the holding power would have not significant difference. Considering the structure of device and stress of sugarcane, 4-layers canvas conveyer belt was used as flexible holding part, while its length is 120mm, 160mm, or 200mm, the corresponding maximum track space is 135mm, 183mm, or 235mm. Experimental investigation of sugarcane windrowing was done on the arc-track-type flexible holding and conveying test mechanism.

随着轨道间距的增大，柔性夹持元件施加给甘蔗的夹持力逐渐减少；施加给甘蔗相同的夹持力，随着柔性夹持元件帆布帘层数和长度的增加，对应的轨道间距增加；随着柔性夹持元件长度的增大，柔性夹持元件施加给甘蔗的夹持力随轨道间距变化的斜率减小，夹持力大小的变化越缓慢；柔性夹持元件提供的夹持力与轨道间距均呈线性关系；柔性夹持元件夹在甘蔗节上还是不夹在节上，甘蔗有叶还是无叶，其施加给甘蔗的夹持力无显著差异；从夹持输送装置结构以及甘蔗的受力情况来考虑，选择4层帆布帘输送带作为柔性夹持元件更能平稳、柔和地夹持输送甘蔗，4层帆布帘120mm、160mm、200mm长的柔性夹持元件夹持甘蔗所需最大轨道间距为135mm 、183mm、235mm。

Instead of thinking of God as the immutable Prime Mover of the universe, argues Ogden, it makes more sense to describe him as "the ultimate effect" and as "the eminently relative One, whose openness to change contingently on the actions of others is literally boundless."

Ogden主张：与其将上帝视为宇宙不可动摇的主宰，还不如将其视为一种"最终产物"及"和这个世界有着非同寻常关联的事物"更有道理。上帝的可变开度视世界上所有人的行为而定，而因为世界所有人行为的无限，上帝的变化力理论上是无边无际的。

There are many swordplay in monetary theory, these divarication should attribute to the conversion of monetary fuctions.

在今天，大量的金融创新、发达的网络支付系统，使货币理论必须跟随经济的这种变化，在新的经济条件下有更好的解释力。

The results demonstrated that with the increase of twisting velocity, the torque on the hollow structure changes indistinctively. In case of increasing die velocity and target strain rate, the forming force of hot forming and gas pressure of superplastic forming will increase.

研究表明，扭转速度的提高使扭矩仅有较小的变化；当模具速度和应变速率提高时，热成形的成形力和超塑性成形的气压将提高。

These retroactive changes in no way reflects how Australia is seen by many of us.

这些有溯及力的变化绝对无法反映出我们眼中的澳大利亚是一个怎样的国家。

Like reliability, there are technical terms and issues associated with validity that are essential in helping teachers and administrators make reasonable and appropriate inferences from assessment results (e.g., types of validity evidence, validity generalization, construct underrepresentation, construct-irrelevant variance, and discriminant and convergent evidence).

象可靠性，有技术术语，并且是根本的在帮助的老师和管理员的问题与有效性相关由评估做合理和适当的推断发生(即，有效性证据、有效性概念化、修建代表名额不足、修建毫不相关的变化和有识别力和会聚证据的类型)。

In this regard, we would like to quote Dr Zuleika Arashiro, who appeared to be the first person to bring the issue of the so-called " cases on hold " to the public's attention, These retroactive changes in no way reflects how Australia is seen by many of us.

在这方面， Zuleika Arashiro博士，作为呼吁人们关注所谓&积压案例&问题的第一人，曾说过这样一句话，这些有溯及力的变化绝对无法反映出我们如何看待澳大利亚是一个怎样的国家。

This study will contribute to a better understanding of mechanism of bone remodeling during tooth movement which may set the basis for clinical work. Methods1. Observe the expression of ATF4 protein in periodontal tissues after orthodontictooth movementA titanium-nickel closed-coil spring was applied to the occlusal surface of the rat maxillary first molar (M1) with a hook and the upper incisors with a ligature wire.

但正畸骨改建与骨发育是两种不同的生理过程，ATF4在正畸牙齿移动牙周组织的表达和分布，在机械力的作用下体外培养的人牙周膜细胞中表达变化的情况，以及在牙周膜细胞向成骨样细胞分化的过程中所起的作用，国内外尚未有报道。

We found that the microstructures and magnetic properties were not influenced with depositing temperature and sputtering power. The magnetic properties were only affected by Fe layer thickness. When the Fe layer thickness is thinner than 5 nm, weak exchange coupling raised between Fe cap layer and FePt recording layer. When the thickness reached 10 nm, the strongest exchange coupling formed. Film coercivity didn't distinctly vary as Fe layer thickness is thinner than 15 nm. Consequently, we measured DCD curves and had the same conclusions. Indeed, the appearance of exchange coupling is confirmed with 10 nm Fe cap layer.

我们并发现溅镀Fe之温度与瓦数，并不会对结构或是磁性质有显著的影响，Fe厚度的改变虽然也不会改变结构，但是对Cr/Pt/FePt/Fe磁性质却有明显的变化，当Fe厚度薄时(3、5 nm)，在Fe和FePt界面仅有弱的交换耦合力产生，Fe厚度是10 nm时，此时交换耦合力为最强，厚度再增加到15、20 nm时，Hc反而略为上升，同样的我们量测DCD曲线，也证实了Fe厚度10 nm的确有交换耦合力存在。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
