proverbs and sayings Conversation Poem Section B Text A Practice Text B 1 Simulation is a software tool that enables one to design a manufacturing workcell (or indeed an entire manufacturing plant) as to the interaction of major machine components. 2 If a firm wishes to develop a simulation capacity, two broad options are available: one can write the software and tailor the program to the simulation needs at hand, or one can purchase a general-purpose software package and become proficient in its use. One of the more popular high-level languages used in developing one’s own software is the SIMAN simulation language. Interaction n.??互相作用 e.g. Price is determined through the interaction of demand and supply. 价格在供需的相互作用中形成。 Tailor vt.??调整使适合e.g. We can tailor our design to meet your request. 我们能调整我们的设计以满足你的要求。 You have to tailor your spending to your income. 你得量入为出。 就主要机器部件的互相作用而言，仿真是一个使我们能设计生产(工作)单元(或实际上是完整的制造厂)的软件工具。 如果一个公司希望建立仿真能力，可以有两种选择；可以编写程序教件并使程序满足仿真需要，也可以购买一个通用软件包井加以掌握。比较流行的一个用于开发自用的高级语言是SIMAN仿真语言。 译文 3 One of the basic data elements of a simulation system is the geometric modeling of the mechanical components of the workcells. Simulation systems do not do the work of solid modeling software and graphics systems. Rather, geometric data are provided to the simulation program database, either through the output of a CAD system or by vendor-supplied configurational data. Such a database or library may contain a variety of robot models, conveyor systems, machine tools, end effectors, fixtures, and tooling in its memory, in what are called “geometry files.” The simulation program may call up these files to create on a graphics screen the desired placement of all work cell components: robots, machine tools, conveyors, and storage racks. Geometric： adj.??几何学的 e.g. It provides numerous geometric functions. 它提供很多的几何学的功能。 The cube is a solid geometric figure. 立方体是一个牢固的几何图形。 Placement： n.??位置，方位e.g. The referee may adjust the
