Magnetic bearing ( mb ) is a kind of new typical mechatronics product which utilizes the electromagnetic attractive force exerting on a magnetic conductor to suspend a rotor without any contact 磁悬浮轴承( mb )是一种新型的机电式轴承,是利用电磁场对导磁体的作用力而实现对转子的无接触支承。
This alignment caused the attractive force between the positive ends of the water molecules and the balloon to overpower the repulsive force between the negative ends of the water molecules and the balloon 这是由于：水分子带正电荷的一端与气球之间的吸引力大于水分子带负电荷的一端与气球之间的斥力。
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。
Thus the concept of the existence of some attractive force that governs the falling of objects to the earth and their remaining stationary after having once fallen ; as also determining the positions which heavenly bodies occupy , was recognized 因此，存着在一种吸引力支配着物体掉到地面，它们落下之后仍然是保持静止的；同时也决定了天体所公认的位置。
The story of an apple hitting his head might not be true , but he did write down the first theory of gravitation , one of his many important discoveries . according to his theory , there is an attractive force between any two massive bodies 虽然苹果掉在牛顿头上，令他悟出万有引力定律的轶事，很有可能是杜撰的，但无论如何，万有引力定律无疑是牛顿芸芸成就中其中一个重要发现。
Abstract : this paper , by analyzing the effect of differences of mineral structure of 2 1 layer minerals , the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation , reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges . the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals . the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity 文摘:分析2 1型矿物的结构差异、层间电荷性质以及在风化过程中某些性质的变化对层间阳离子吸引力的影响，对已有报道中一些矛盾的结果或不具普遍意义的结论进行了讨论.得出几个较为明确的结论：层间总电荷与四面体电荷所占比例大小共同决定矿物对层间阳离子的固定能力；原生矿物中八面体结构与层间阳离子固定间的关系对次生矿物而言，也许并不一致；八面体中可变价阳离子的氧化还原，可导致矿物固定阳离子能力发生较大变化
Microdeformation mechanism of structural clays and elasto - viscoplastic damage model abstract on the basis of the investigation of the structure of natural sedimentation clays and the simulation of the deformation and rheology of soil particle skeleton under the internal molecule attractive force and electric charge repulsion and the exterior load , a elasto - viscoplastic damage model is constructed in which the soil structure is considered to be gradually damaged in the course of loading , and the effectiveness of the model is verified by the results of laboratory tests and field tests 本文调查了天然粘土中存在的结构性，应用大变形有限元法模拟了土颗粒骨架在内部分子吸力和电荷斥力以及外部荷载作用下的变形和蠕变机理，在此基础上建立了考虑天然粘土变形过程中结构性不断受损的弹粘塑损伤模型，并进行了室内和现场试验，论证了模型的有效性。
