伸缩量 meaning in Chinese
stroke
Examples
- Extend the pipe out from the support of 1 / 2 expansion amount to ensure the moving of expanding and shrinking
安装时使伸缩管伸出伸缩量的1 / 2 ，以保证热胀和冷缩的位移。 - The css is implement with the resource kernel model . then present a dynamic slack sharing algorithm to replace the fixed one used in css
经过对该算法的初级分析，可以看出动态伸缩量分配算法能够提高实时系统的各项性能。 - In this dissertation , the development survey , research actualities and application prospect of vamt are introduced at first , and the models of kinematics , dynamics and linear motor servo are analyzed then . currently the dynamics model is complex or established mechanically , which restricts the study of control theories . thus this dissertation present a simple and easy - realized control idea , namely , the fore and torque of every leg determined by the inverse - solution of mechanics are regarded as changeable load force ( disturbance ) applied in motor , the elongation of the leg or displacement of sliding is regarded as the output of linear servo system
本文首先介绍了虚拟轴机床的发展概况、研究现状和应用前景，然后对其运动学、动力学、直线伺服系统模型进行分析，针对目前动力学模型过于复杂或完全从机构学角度建立不便于控制的问题，提出了简单、易于实现的控制思想，即将虚拟轴机床的动力学方程反解所确定的各杆受力(矩)视为电机的可变负载力，以杆长伸缩量或滑块位移为伺服系统输出，从此构成位置闭坏，实现轨迹跟踪控制。 - In general , polycrystal or twin magnetostrictive materials are used as the drive unit in micro - displacement actuator . however , the displacement output of the actuator under low magnetic field is small and its precision is limited , as a result of motion restriction of magnetic domain walls by grain boundaries in polycrystal or twin magnetostrictve materials
磁致伸缩是一种磁?机械耦合现象，以tb - dy - fe为代表的稀土超磁致伸缩材料，其伸缩量为普通压电陶瓷的30 - 50倍，响应时间低于10 . 6秒，是理想的位移致动材料。 - The duty of real - time system is to provide time constraint guarantees for the real - time applications , in other words , it make the applications access to the resources they need timely . many works have devoted into individual resource scheduling ( i . e . processor capability , disk bandwidth and network bandwidth ) . obtaining simultaneous and timely access to multiple resource is known to be a np - complete problem
大量的研究工作集中在单纯的网络带宽、磁盘带宽和处理器资源各自的调度优化上，而在同一个节点上同时使用多个资源的是比较复杂np完全问题，本文分析了一种在资源预留系统( resourcekernel )中解决该问题的途径，联合调度服务器( css ) ，并对其中的关键问题? ?伸缩量分配( slacksharing )作出了改进，提出了一种基于当前系统负荷的分配算法。
