众文网1.哪位大师能帮忙翻译下论文摘要,我在网上翻译的都不对,有错误,
mart as a new product in our daily life in modern society, the application of already more and more broad, the emergence of intelligent product development for people's life and made a very big contribution, now society has become more and more intelligent.
The main task of this design is on the basis of the intelligent car, equipped with photoelectric detector, realize the electric car's speed, position, obstacle avoidance, QuGuang, running status in real time measurement, H bipolar PWM converter is adopted to improve the speed, the use of infrared diffuse reflection effect of obstacle avoidance module, the data is transmitted to the single chip microcomputer for processing, using the nRF401 radio communication module implements data communication between MCU and PC to realize intelligent control of electric vehicle.
望采纳！
2.论文摘要翻译,我最近急着用,有点错误可以,但不要太多,更不要用
摘要内容：随着汽车行驶速度的提高，汽车阻力也明显加大。
Abstract: when the vehicle speed increases, its resistance obviously increases as well.研究表明：车速达到70km/h时，汽车阻力占行驶阻力的一半。Research shows that when vehicle speed reaches 70km/h, its resistance takes up half of the driving resistance.汽车速度过高对汽车的稳定性、安全性也有着很大影响。
The excessive vehicle speed has great influence on the stability and safety of the vehicle.现阶段空气动力学研究一般都采用风洞试验、数值模拟、理论研究。The current aerodynamics research generally adopts wind tunnel test, numerical simulation and theoretical research. 风洞试验室运用最为广泛，但其投资过高、周期长等缺点。
The wind tunnel test is the most commonly used, but it has disadvantages such as too much investment, long cycle and etc. 随着计算机的发展，数值模拟取得了很大的发展（CFD）。With the development of computer, the numerical simulation has had huge development (CFD).CFD是以电子计算机为工具，应用各种离散化的数学方法，对流体力学的各类问题进行数值试验、计算机模拟和分析研究，以解决各种问题。
CFD uses different mathematical method of discretization by means of computer to test, stimulate, analyze and research various problems of hydromechanics and etc. so as to deal with these problems.CFD具有试验周期短、费用低等优点。CFD has these advantages such as short test cycle, low cost and so on.目前的模拟是CFD和风洞试验相结合的方法，互相促进，CFD还不能完全取代风洞试验。
CFD and wind tunnel test are adopted in current simulation and they mutually promote, but CFD cannot totally replace wind tunnel test.本文首先对汽车流场发展和研究意义和CFD软件包做了介绍。This paper first introduces the development of flow field and CFD software package.第二章中对CFD的理论基础进行了讲解。
It illustrates the theoretical principle of CFD in the 2nd chapter.第三章主要说明利用GAMBIT建立汽车模型、网格划分以及边界条件的确定。In the 3rd chapter it mainly explains the utilization of GAMBIT to make car model, the grid generation and the determination of edge condition.在第四章中说明FLUENT进行模拟的一般步骤。
The 4th chapter gives out the general procedures of FLUENT simulation.第五章中对不同的汽车前部后部造型进行模拟对比，了解汽车前后造型设计的基本思路。In the 5th chapter simulated comparisons are made about the shape of the front and rear part of different vehicles in order to understand the basic idea of their design.汽车前部发动机盖应与水平面成一定斜度，汽车顶部与发动机盖在同一曲面上，汽车尾部为鱼尾巴形的汽车造型最优。
The front vehicle hood should form a certain slope with the horizontal plane. The vehicle roof and hood should be on the same curved surface. Those vehicles with fishtail-shaped rear part have the optimum shaping.还对汽车的不同离地距离和不同行驶速度进行了分析对比。Analysis and comparison is also made in different ground clearances and running speeds of vehicle.汽车离地距离小，汽车升力增加，气动阻力减少。
When the vehicle ground clearance decreases, the lift will increases, thus reducing the aerodynamic resistance.汽车速度增加是周围空气速度和阻力将明显加大。The increase of vehicle speed obviously increases the ambient air speed and resistance.合理的确定造型和最优的离地距离对汽车阻力减少影响很大。
The reasonable shape and optimum ground clearance has huge influence on the decrease of vehicle resistance.-----------------------------------------------------------------------------------------------Copyright@2010 Lawrence. All rights reserved.。

Jetta cars in China had 19 years, with its economic and practical, inexpensive, appearance is moderate, motivation, especially good enough, accelerating performance by consumers. But the pen jetta cars (AHP model engine) in use will happen various fault. Introduces the jetta cars (AHP model engine) under several faults in the reason, in the analysis is proposed, based on the troubleshooting measures.。
