A jeffcott rotor which is simple supported at its two ends is established first in this article . the disc comes under the effect of the air exciting - vibration force due to the eccentricity 本文首先建立了一个两端简支的jeffcott转子模型(短直叶片转子) ,圆盘偏心时受到不均匀间隙汽流激振力的作用。
For robotic nanomanipulation based on an atomic force microscope ( afm ) , the working principle of interactive nano forces among the probe , substrate and particle is preliminarily analyzed 摘要针对基于原子力显微镜( afm )的机器人化纳米操作，对探针作用下探针基片微粒之间纳观力的作用规律进行了初步分析。
The highly capable engineering team implemented all of the specifications with regard to introduction of force , fitting or attachment position , display position and compactness , to tight deadlines 具有强大实力的工程师队伍在短暂时间下实现了与力的作用配合和连接位置显示屏位置以及紧凑性相关的所有规格。
In steel frame beam - to - column connections play a vital role in transferring bending of moments and shearing force , and their behavior affects steel frames overall performance under loads 钢框架中梁柱连接起着在两种构件之间传递弯矩和剪力的作用，是钢框架的主要组成部分，它的性能直接关系到结构的整体反应。
Law can not be abided by is not good law . the force which comes from regime and the applicability of law sometimes appears a kind of interactive process 更为复杂的是，先进性与适应性有时还表现出某种互动，法律制度是一种行为规则，通过外界强制力的作用，先进性和适应性在许多情况下取得一致的情况也并不鲜见。
The infrared analysis show that the a small quantity of transition of crystal form from a into y of nylon and its composites happen during dry friction because of the high temperature and strong sheering strength 红外分析显示在干摩擦磨损过程中，磨损表面在高温及强剪切力的作用下，发生了少量晶型到晶型的转变。
One of the most important innovations in his analysis was the application of the theory of probability to account for the statistical variation of the agitating forces on bed particles caused by turbulence 他著作中的重要革新是使用了概率论，当流沙床面在受到力的作用时，用这个概率论来计算床面颗粒搅动力的统计变化。
I believe that the teachers have a great and more influential role in running the school than in china because of strong teachers unions , or groups of teachers united to speak in a joint voice 我觉得老师们在掌管学校时起着一种比中国更大或更有影响力的作用，因为有个强大的教师工会或者有一个有共同心声的教师联合群体。
Trunk orthosis is a kind of instrument that prevents and rectifies malformation in human bodies , and cures diseases in bone joints , muscles and nerves . also it partly compensates for the functions of the disabled muscles 躯干矫形器是作用于躯干，通过力的作用以预防、矫正畸形，治疗骨关节及神经肌肉疾病并补偿其功能的器械。
The research of the bend stress of fg drive is made by the use of finite element analysis ( fea ) . the influence of the force location on the calculating stress of the bend strength is considered 在面齿轮传动的弯曲应力的研究中,利用有限元分析法对面齿轮的弯曲应力作了分析;考虑了力的作用点对弯曲应力的影响;获得了弯曲应力的分布规律。
