In order to prove the reliability, test studies have been primarily carried out in the indoor soil bin. The data of the vehicle driving state parameters under the same or different terrain are analyzed. The process curves are compared by different control schemes. The theoretical model of the optimum driving state is reliable and fuzzy control scheme is feasible. The disturbances and unknown factors of control system are analyzed. Test results prove that the half-tracked air-cushion vehicle can drive steadily under control of the computer. At the same time the sensors used to measure soil mechanics characteristics on line need to be developed. And it is the important problem to be solved in the future study. The necessary regulation and correction are put up. So the studies in this paper provide some instruction for the further research work.

Mr. Chuffart was directly responsible for several highly acclaimed concept and production cars for Nissan ranging from small cars (the current generation Nissan Micra), to mid-size cars to large luxury cars and four by four (recently released X-terra in US and future Armada replacement).

从小型车到中级车（下一代尼桑Altima）再到豪华车和四轮驱动车（近期在美国上市的X-terra和将来更新的Armada），由Chuffart 先生直接负责的这几个被高度赞扬的概念车以及将要量产的汽车帮助尼桑创造并实现了今天被人们所认知的尼桑系列化产品。

You can get a great recumbent for around $1000, and this is the price range you should be looking in if you will be riding once a week or more. If you are a casual rider, or on a limited budget, you will want to start out with one of the lower priced recumbents. High end recumbent bikes and trikes can be priced up to about $7000. Paying higher prices for a recumbent will buy you things like light weight, space age components, exotic materials, suspension, and more speed

在1000美金的价位你可以得到一台不错的躺车但是花这些钱你要考虑你只每周骑 1次还是更多如果你只是一个偶尔骑骑车的人或者你的预算受限制你应该从一个比较低端的躺车入手高端2论躺和3论躺车可以高达7000美金为躺车投入高额可以让你得到很轻的重量太空级别的配件进口的材质，减镇悬挂，和更快的速度

If you don't want to deal with that balancing thing, like to ride on the ice, or just think trikes are cool, there are recumbent trikes available for every task.

如果你不想处理平衡方面的事情譬如说在冰路面上骑行，或者觉得3论车更酷，那么就选择3论躺车吧它可以胜任任何任务，通常来说倒三轮躺车（2个轮子在前面）更加适合弯道（兔子译注尤其在高速转弯时倒三轮子躺车更加稳定）而正三轮子躺车在高速行驶时更加稳定

Certainly defend the lock dead car system is at the car wheel locks to die just have the function, if you drive through frozen on the road, want ～only a the car ABS possibility keep move;Again if you changed a the set grasps the super and strong and big size heat of land productivity to dissolve the , open to face in the flat and dry road, if your car system did not enhance, calculate you use to make an effort to step on the car pedal, perhaps the ABS has no action still, because your car of system motive combine shortage with lock tire dead.

防锁死剎车系统当然是在车轮锁死时才有作用，你如果开车经过结冰的路上，只要你轻点剎车ABS可能就动个不停；又如果你换了一组抓地力超强的大尺寸热溶胎，开在平坦干燥的路面，如果你的剎车系统没有强化过，就算你用尽全力踏在剎车踏板上，说不定ABS依然没有动静，因为你的剎车制动力并不足以将轮胎锁死。
