- Gravity is a very weak attractive force. 地心引力是一种非常微弱的引力。
- The interaction between two surfaces is the result of repulsion and attraction forces. 两个表面间的相互作用是由于吸引力和排斥力作用的结果。
- magnetic attraction force bearing 磁悬轴承
- The attractive force increases as a gas is compressed and its molecules are brought closer together. 随着气体被压缩，气体分子之间的距离缩小，引力增大。
- The earth's atmosphere is in hydrostatic equilibrium under the combined action of the gravitational attractive force of the earth and the pressure of the gases in the atmosphere. 地球大气就处于地球引力和大气中气体压力共同作用之下的流体静力平衡状态。
- A study from a Canadian university shows that those who drink even moderately develop a reduced ability to rate attractiveness, even when they are sober. 加拿大一所大学的最新研究表明，常饮酒的人审美能力会下降，即使在清醒的情况下也如此。
- We have a weight because the Earth exerts an attractive force on us. We call this "gravity". 我们有重量是因为地球在我们身上有一种吸力,称为“重力”。
- The two bodies are so far apartthat the attractive force between them is negligible. 这两个物体相距很远,它们之间的吸引力可以忽略不计。
- At this rate we won't be able to afford a holiday. 照这样下去，我们不会有时间／钱去度假的。
- The dedusting performance of traditional wet scrubbers,based on gravitation,can remarkably be improved by making use of electrostatic attraction forces between particles and droplets. 着重分析液滴荷电而颗粒不荷电的湿式除尘器的工作状况,阐述了布朗扩散、拦截、惯性碰撞和静电捕集等4种除尘机理。
- One possible scenario is that the initial high-density state arose when a preexisting universe collapsed under the attractive force of gravity. 一个可能的说法是，当先前存在的宇宙因受重力的吸引而塌缩时，会产生高密度的初始状态。
- The strong hydrophobic attractive force between molybdenite and bubble interface is the basic reason which causes the natural flotability of molybdenite. 辉钼矿与气泡之间的强疏水引力是辉钼矿具备天然可浮性的根本原因；
- The growth of these structures was initially driven only by the attractive force of gravity, but then later there was competition with the repulsive force of dark energy. 这些宇宙空间中的结构最初是由于万有引力的作用开始进化的，但不久之后就有暗能量的反重力作用与其对抗。
- The electromagnetic iron-separator is a device using the electromagnetic attractive force to separate the ferrom agnetic materials from the non-ferromagnetic malerials. 电磁除铁器是一种利用直流电磁线圈的电磁吸力将铁磁物质从非铁磁物质中分离出来的磁分离设备。
- What's the going rate of computer programmers? 计算机程序设计人员的一般工资是多少？
- By power we mean the rate of doing work. 我们说功率就是指做功的速率。
- His house was rated at$300 a year. 他的房子估计每年应交300美元的税。
- He is rated one of the rich men in Texas. 他被认为是德州最富有的人之一。
- Then a new attractive force function and a new repulsive force function are deduced, which the robot can adjust its velocity to escape from obstacles, and move to target quickly, or track target synchronously. 在新的势场函数作用下机器人能够快速调整自身的速度大小和方向，使其快速脱离障碍物的威胁并能快速地到达目标或追踪目标。
