有保持力的

10As a railroad or an automobile passes around a curve some agency must supply a force directed toward the center of curvature in order that the moving body shall remain on the track or road .

当有轨电车或汽车沿弯道行驶时，必然有某种作用提供一个指向弯道中心的力，以便运动的有轨电车或汽车能继续保持在轨道或公路上行驶。

Dawdler exceeds love certainly th is walks, sit move, station is worn also the good method of can thin body.

坐姿时腿弯曲的地方要保持90度，有一部分力量会集中到腿上，而不是全部让腰来受力，腰才不会酸痛，角度不够可以垫书。

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 prestressed reinforced concrete continuous rigid frame bridge is a kind of bridge which is nice wholeness , bearing property and has bright and pithiness bridge style .

预应力混凝土连续刚构桥是一种结构整体性好，受力合理，造型简洁明快的混凝土桥型，既保持了连续梁无伸缩缝，行车平顺的特点，又有T型刚构桥不设支座，施工方便的特点。

Cracks are more slightness and more dense , and will be closed after being unloaded , and the walls will not fall apart with cracks , which indicate that such walls may retain the entirety well and have good resistance of collapse

试验表明施加预应力后，砌体墙的抗剪能力、变形能力和延性都有所提高，而且墙体受力均匀，材料性能发挥充分，卸荷后裂缝闭合，砌体墙"裂而不散"，保持了较好的整体性，有良好的抗震、抗倒塌性能。

Product features include : 316 import hairpin will not break off if circumvolving by 180 degrees, repeating for three times remain 3-8KG pounds and 3/4 hardness. The 316L material machine's teeth are clear and teeth diameter discrepancy is +0.02mm etc.

产品的特色有：316进口发夹可连续三次180度不折断，反复折3次仍保持3-8KG磅力，3/4硬度316L料花枝牙缝清晰、牙直径差±0.02mm等等。

The results showed that although 2n pollens had a certain germinatingability,the germinating process of natural and artificia 2n pollens was tardier than that of1n pollens,and 2n pollens had weaker competition in mixed pollination than 1nbreeding practice.

应用这种方法对2n花粉生命力和发育情况进行测定观察发现，尽管2n花粉保持有一定的萌发力，但与1n花粉相比，天然和人工2n花粉的发育进程均较迟缓，在参与授精的竞争中处于劣势，这也正是育种中三倍体得率低的根本原因。

With the harmony between vertical and lateral deformation of long rail components taken into account, a transition locking structure for large expansion volume, an ending structure of the switch, a nose rail that both transfers longitudinal force efficiently and maintains turnout regularity, and a fastener system suitable for both ballast and ballastless track were developed to solve the transition choking problem of jointless turnout.

为解决无缝道岔转换卡阻问题，在考虑长大轨件纵横向协调变形的基础上，研发了适应大伸缩量的转换锁闭机构、既可有效传递纵向力又可保持道岔平顺性的尖轨及心轨跟端结构和适用于有砟和无砟轨道基础的扣件系统。

More importantly, the group has discipline and editing skills, keeping this record at a tight 36 minutes and 41 seconds, a move that makes it considerably more listenable than its peers and, by extension, more powerful, since they know where to focus their energy, something that many nu-metal bands simply do not.

更重要的是，此乐队有自己的原则和编排技巧，从而将整张专辑保持在了36分41秒，这样的做法使得此专辑相比同行的专辑更加耐听，同时也更加有力，这是因为他们知道应该把力道发挥到哪里，而许多其他的新金乐队都没有做到。

"Force :Action that tends to maintain or alter the position of a body or to distort it. It is a vector quantity, having both magnitude and direction. Force is commonly explained in terms of Newton's laws of motion."

&力：力学中指任何使物体保持或改变位置或使物体变形的作用，力是一种矢量，有量值和方向，这一概念通常是按照牛顿运动定律所用的术语来解释的。&
