Mountain bikes either have some form of caliper brakes, which are the kind of brakes typically associated with bikes.

山地自行车或者有某种形式的卡钳刹车，这是种制动器通常与自行车。

This text will apply the integrative technique of CAD/CAE to the key parts (brake drum、brake shoe) in the drum brake which is the medium-sized camion of export Russia , put forward to achievement the entity sculpt of brakes drum and brake shoe on the base of technique of CAD/CAE, and depend on its force condition to make analysis of Generative Structure ,to make sure the rationality of the structure design.

本文对出口俄罗斯的中型载重汽车的鼓式制动器中的关键件进行了CAD／CAE一体化技术的应用，在基于CATIA软件的平台上，进行制动鼓及制动蹄片的实体造型，并根据其受力情况进行了有限元分析，提出了优化结构的改进设计措施，使结构设计趋于合理。

Its operating principle is that electric energy is changed into mechanical energy by drive unit, then the liquid in the cylinder body forms high and low pressure to drive piston up by impeller circumrotation, so vertical motion is changed into wagging of brake arm by leverage and declutch is completed. This product has passed the experiment test by National Quality Supervise Administration and every technical criterion is accorded with national trade standard.

电力液压块式制动器包括电力液压推动器和块式制动架两部分组成，其工作原理是通过驱动装置的电能变成机械能，通过叶轮旋转，使缸体内液形成高低压腔推动活塞向上运动，从而通过杠杆机构将垂直运动转变成制动臂的左右摆动、完成松闸。

为单人撤离用而设计，缓降器上有速差式备用制动器，可以存放在现场-与锚点连接可用于备用/即用，可在大多数配有全身安全带或扣眼式安全带的降落中使用。

The paper analyses the effect of brake resistance of discal brake stop system,stain of brake_plate and the rellability of hydraulic station on elevator's safety running by abundantly spot testing.

通过大量的现场测试，分析了盘式闸制动系统的制动器阻力、闸盘污染以及液压站的可靠性对提升机安全运行的影响，提出了改造意

The friction force in the clutch works just like the blocks in the frication section of brake, except that the spring presses on the clutch plate instead of weight pressing the block into the ground.

离合器的摩擦力和制动器的摩擦力起一样的作用，不同的是压在地面上的重压力变成了离合器中弹簧压在离合器盘上的压力。

Secondly,two regulatable current sources for exicitation of magenetic powder dynamic brake are studied respectively with buck and interleaving two-transistor forward topology. In the power supply with interleaving two-transistor forward topology design,simulations are implemented with Saber simulator,thus the best parameters are achieved which ensured the stability and dynamic characteristic.

二、分别用 BUCK 式和交错并联的双管正激式电路拓扑，研制了磁粉制动器的直流励磁电流源，其中对于交错并联双管正激式的电路进行了基于 Saber 的仿真，确保了电路参数的选取能够保证电路稳定性与动态性能要求。

The microcomputer is used to monitor the whole system and reprocess the data. The single chip computer which is the center of the whole control system is used to collect and process the data, adjust the speed of the AC electromotor and control the magnetic brake.

微型计算机用来完成对整个系统的监控和数据的后处理，而单片机系统是整个控制系统的核心，试验数据的采集和前处理、交流电机的调速控制、磁力制动器的控制都由它完成。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
