1.With low-power machinery or vehicles the operator can usually apply sufficient force through a simple mechanical linkage from the pedle or handle to the stationary part of the brake. In many cases, however, this force must be multiplied by using an elaborate braking system.（P5）用低能机器或传力工具，操作者通过向踏板或把手的一个简单机械连接构件作用足够的力量到车闸固定的部分。大多数情况，然而，用一个详细（复杂）的车闸系统使这个力量成倍增加。
2. The fundamental principle involved is the use of compressed air acting through a piston in a cylinder to set block brakes on the wheels. The action is simultaneous on the wheels of all the cars in the train. The compressed air is carried through a strong hose from car to car with couplings between cars; its release to all the separate block brake units, at the same time, is controlled by the engineer. (Braking Systems)（P5）
相关的基本原理是使用压缩气体，通过气缸内的活塞将闸块压在车轮起作用。列车的所有车厢上的车轮同时动作。压缩气体通过一个坚固的管道在由联轴器连接的车厢之间传输；工程师控制其在同一时间释放到所有独立的闸块单元。
3.When the brake pedal of an automobile is depressed, a force is applied to a piston in a master cylinder. The piston forces hydraulic fluid through metal tubing into a cylinder in each wheel where the fluid’s pressure moves two pistons that press the brake shoes against the drum. (Braking Systems)（P5）
当踩下汽车刹车的踏板，在主汽缸中的活塞上施加一个力。活塞驱动液压流体通过金属管道进入每个车轮气缸，在那里液压移动两个活塞将闸片压向轮圈。
4.Machinery ontology including mechanical rack, mechanical connections and mechanical transmission, which is the basis of mechanical-electrical integration, plays a role in supporting the other functional units of the system and transmitting motion and power. Compared to purely mechanical products, the performance and functionality of integration technology in electrical and mechanical systems have been improved a lot, which requires mechanical ontology to adapt its new status in mechanical structure, materials, processing technology, as well as the areas of geometry. Accordingly, the new ontology is with high efficient, multi-functional, reliable and energy-saving, small, light-weighted and aesthetically pleasing characteristics. (Mechatronics System) （P7）
机械体包括机架、机械联接和机械传动，它是机电一体化的基础，作用是支撑系统其他功能单元，传递运动和动力。和纯机械产品相比，一体化技术的性能和功能在机电系统中大幅提高，它要求机械本体适应在机械结构、材料、加工技术以及这些领域中的几何学下的新环境。相应的，新的一体化具有高效、多功能、可靠、节能、小轻和美学的令人赏心悦目的特征。
5. Detecting sensor detecting sensor part includes a variety of sensors and signal detection circuit, and its function is to detect the process of mechatronic systems in the work itself and the changes of relevant parameters in external environment and transmit the information to the electronic control unit. Electronic control unit check the information and sends the corresponding control issues to the actuator. (Mechatronics System) （P7）
检测传感器部分包括各类传感器、信号检测电路，它的功能是检测机电系统自身工作的工程，在外部环境下的相关参数的改变，将其信息传给电子控制单元。电子控制单元通过检查信息，送出相应的指令到执行机构。
6. Electronic control unit, also known as ECU, is the core of mechatronic systems, responsible for the external commands and the signals output by sensors. It centralizes stores, computes and analyzes the information. Based on the results of information processing,instruction are issued according to a certain extent and pace to control the destination for the entire system. (Mechatronics System) （P7）
电子控制单元，也被称为控制单元（ECU）控制，是机电系统的核心，负责外部命令和传感器的信号输出。它集中、存储、计算并分析信息。基于信息处理的结果，按照一定的范围和步调发出命令来实现控制整个系统的目标。
7. It is put into a fairly standard machine tool that has had position sensing and motors on the
