The improved slide plate used for speed-up turnout can on one hand provide endure, reliable and constant tightening of inside of stock rail and, on the other hand, can flexibly match the gauge adjusting of stock rail. Besides, roller plate can reduce the switching resistance and the deficient displacement of tongue rail so as to realize the reliable switching.

改进型滑床板一方面能持久、可靠的扣压基本轨内侧，保持扣压力的恒定，另一方面能够方便、灵活的配合基本轨的轨距调整，此外滚轮滑床板减小了道岔转换阻力，降低了尖轨的不足位移，确保道岔转换可靠。

Firstly, based on the sliding mode control and backstepping technique, a new attitude tracking controller is derived to control the attitude motion of spacecraft, the stability of the system is analyzed via Lyapunov method and the reaction wheel dynamics is also considered from the real applications point of view. The whole design process is divided into two steps: the first step is to use sliding control technique to design suppositional adaptive variable structure controller; and the second step is to design attitude tracking controller based on SMC and backstepping technique. Numerical simulations are performed to show that both tracking maneuver and vibration suppression can be accomplished effectively.

首先，采用自适应后步法结合主动振动控制技术设计了姿态跟踪鲁棒控制器，基于Lyapunov方法分析了系统的渐近稳定性；在此基础上，显性地考虑了执行机构动态特性问题，将整个设计过程分为两个步骤：第一步采用滑模控制技术设计了变结构虚拟控制器，给出自适应控制律的设计方法；第二步，将后步法与滑模控制技术相结合，设计了姿态跟踪鲁棒控制器，给出飞轮电压的输入算法及稳定性分析；最后，将提出的控制方法应用于挠性航天器的姿态跟踪控制，通过数值仿真对所提方法的可行性与有效性进行分析和验证。

Two pairs of chutes and holes on the cleaning base and the brushes form the double chute swing mechanisms by the connection of an axis and cause the brush to cling to the wall surface to clean by the friction feedback, thus achieving effective cleaning when walking error occurs and the pipe section changes, furthermore, the larger the friction on the wall surface is, the larger the forward pressure on the wall surface is, therefore, the dirtier the wall surface is, the higher the cleaning efficiency is.

清扫底座与刷子夹上的两对滑槽和孔通过轴的连接形成双滑槽摆动机构，并通过摩擦力反馈使得刷子能够紧贴壁面进行清洗，从而在出现行走误差和管道截面变化时都能够有效清洗，并且壁面摩擦力越大刷子作用在壁面上的正压力越大，因此壁面越脏时清扫效率越高。

The temperature of flue gas out of air preheater in boiler is normally about 120～180℃, the flue gas enter the absorb tower from the bottom via pre-deduster and is accelerated by venturi tube at the bottom of absorb tower, then is taken to circulating fluid bed. The materials are in the circulating fluid bed, due to the effect of flow, the gas-phase and solid-phase generate fierce turbulence and combination and are fully contacted, then form polymers constantly during the ascending and return downward, while the polymers are constantly disassembled during fierce turbulence and elevated by airflow, which makes the slip velocity between gas and solid reach the tenfold times of single slip velocity.

首先从锅炉的空气预热器出来的烟气温度一般为120～180℃左右，通过预除尘器后从底部进入吸收塔，然后烟气通过吸收塔底部的文丘里管的加速，进入循环流化床，物料在循环流化床里，气固两相由于气流的作用，产生激烈的湍动与混合，充分接触，在上升的过程中，不断形成聚团物向下返回，而聚团物在激烈湍动中又不断解体重新被气流提升，使得气固间的滑移速度高达单颗粒滑移速度的数十倍。

The baby comes on the screen when the tube called a transmitter slides over the mother's skin.

当医生把一种叫传感器的管子在妈妈肚子上滑来滑去时，孩子的图像就会出现在那个屏幕上。

Jason had spent several lunch hours with the real thing in front of him, his friends gathered around to try their hands as well, practicing and practicing--and the one time he did forge a permission slip--a lousy permission slip for a trip to the Bronx Zoo, for Pete's sake--the teacher had called him on it, phoned Anderson, and gotten Jason punished like he wouldn't have believed.

杰生已经在他之前用真正的事物度过一些午餐数小时，他的朋友在附近聚集也试他们的手，练习和练习--和次他确实伪造许可滑--污秽的许可为到布隆克斯区动物园的一次旅行滑倒，为彼得的缘故--老师已经在它上打电话给他，音响的强度单位了安德逊，而且争取杰生处罚了他不会相信的同类。
