First, characteristics of product models in traditional design and concurrent design are compared. Therefore, thoughts of design object and design process working in the double harness are put forward. And, two typical representation methods of product model, and their localization are expatiated. Concept of generalized engineering semantic feature is defined. State of product design model is expressed. Then, an integrated representation method of product model is advanced. Based on the Pro/Engineer software platform, product-modeling system for product general information model is set up.Second, relationships between different product models and approach of data exchange are analyzed.

首先，分析和比较了传统设计与并行设计中产品模型的特点，提出了并行设计中同时考虑设计对象并行与设计过程并行的思想；在阐述两种典型产品模型表示方法，分析其片面性的基础上，引入了广义工程语义特征的概念，表达了产品设计模型的状态，提出了一种集成的产品模型表示方法；基于Pro/E软件平台，建立了产品广义信息模型建模系统。

The content as following:Chapter one introduces the development and actuality of ATS and technology of VXI_BUS test software platform.

本论文的内容安排如下：第一章介绍了自动测试系统的发展及其现状和VXI总线测试软件平台的相关技术。

Design for Software Platform of ATS Based on Signal-Oriented.

面向信号的自动测试系统软件平台的设计。

Then, this system was applied to analyze the influence of interfering factors towards the parameters of LRE for monopropellant (H_2O_2) and bipropellant (N_2O_4/UDMH) system, which include the effect of upstream pressure of the tank and the diameter of the pipelines on the thrust. Thus, the variety of main parameters such as thrust, impulse, and chamber pressure were obtained at rated condition.

本文还以MATLAB软件作为设计平台，使用M文件编写了挤压式液体火箭发动机的静态系统仿真程序，分别针对单组元(H_2O_2)和双组元(N_2O_4／UDMH)推进系统进行了干扰因素对发动机参数的影响分析，包括贮箱上游压力以及管路直径对发动机推力等参数的影响。

The embedded AVN equipment consists of the vehicle's positioning subsystem, the embedded hardware platform and the embedded AVN application software.

本文研究的嵌入式汽车自主导航仪由汽车定位子系统、嵌入式硬件平台和嵌入式汽车自主导航软件构成。

The algorithm of utilizing accelerometer sets to realize dead reckoning is studied. The hardware platform of AVN equipment is researched and developed based on embedded system. The embedded AVN application software is also designed and developed in this dissertation.

本文研究了利用加速度传感器进行航位推算的算法，研制了嵌入式汽车自主导航仪的硬件平台，并设计和开发了嵌入式汽车自主导航软件。

The vehicle is positioned by GPS aided with dead reckoning. System controlling, data collecting and processing, and the navigation information output are done by the embedded hardware platform. The embedded AVN application software calculates the vehicle's geographic position, velocity, and the direction real-timly through the vehicle's positioning subsystem, selects the best driving path according to the demand, and does navigation processing, outputs the navigation information through electrical map and voice, which guide the driver to reach the destination quickly, safely, and straightly.

汽车定位子系统以GPS卫星定位为主、航位推算为辅进行汽车定位；嵌入式硬件平台进行系统控制、数据采集和处理、导航信息输出；嵌入式汽车自主导航软件通过汽车定位子系统，实时解算出车辆的地理位置、速度、方向等信息，并根据需求自动演算最佳行驶路线，在行驶过程中实时进行导航处理，同时将这些信息通过电子地图和语音提示的方式反映出来，从而引导驾驶员快速、安全、准确地到达目的地。

With regard to the software designing, Delphi is used to build the platform for users and also to complete the design of WIS by programming.

软件设计，包括通信连接、使用Script语言进行图像预处理和用户使用平台的设计，使用高级语言Delphi编程，实现纸病测试系统的各项功能。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
