英文高手帮我翻译一下这段文章啊谢谢，在线等2

承载式车架也称作整体式或单体式车架。针对大梁式车架质量重、体积大、重心高的问题，承载式车架的意念是用金属制成坚固的车身，再将发动机、悬架等机械零件直接安装在车身上。这个车身承受所有的载荷，充当车架，所以准确称呼应为“无车架结构的承载式车身”。承载式车架由钢经冲压、焊接而成，对设计和生产工艺的要求都很高，这也是中国目前的车身设计开发难以突破的大难点。成型的车架是个带有坐舱、发动机舱和底板的骨架，我们所能看到的光滑的汽车车身则是嵌在骨架上的覆盖件。承载式车车架是目前轿车的主流，因为这种结构将车架和车身二合为一，重量轻，可利用空间大，重心低，而且冲压成型的制造方式十分适合现代化的大批量生产。但是除了开发制造难度高外，刚度（尤其是抗扭刚度）不足也是承载式车身的一大缺陷。
这问题在日常用车上还不明显，但对于大马力、大扭力的高性能跑车，要求有很高的车架刚度，普通承载式车身就显得刚度不足。因此近年的高性能汽车，除了马力不断提升外，各车厂也不断致力于提高车身的刚度，目前主要采取的办法是优化车架的几何形状和采用局部增粗或补焊以加强抗扭能力。
由于承载式车架将全车所有部件，包括悬架、车身和乘员连成一体，具有很好的操控反应，而且传递的震动、噪音都较少，这是大梁式车架不可比拟的。因此不仅是轿车，就连一些针对良好道路环境设计的越野车也有弃大梁车架而改用承载式车身的趋势，这就是所谓的“城市化越野车”。
另外针对大梁式车架地台高的弊病。近年还出现了采用承载式车身的大型客车（称为“无大梁车身”或“无阵车身”），由于取消了大梁，旅游大巴可以在车底腾出巨大且左右贯通的行李空间，用于市区的公共汽车则可以将地台降至与人行道等高以便于上下车（要配合特殊的低置车桥）。低地台是客车的一个重要发展方向。
钢管式车架前面曾说过承载式车架的设计开发和生产工艺都复杂，只适宜大批量生产。但是对于少量生产的轿车又如何呢？

Bearing Frame, also known as a whole or single-style frame. Beam-type frame for the quality of heavy, bulky, high center of gravity, carrying the idea of Frame is made of solid metal body, and then the engine, suspension and other mechanical parts installed in the car body directly. The body to bear all the load and act as a frame, it should be accurately referred to as "bearing-type frame structure of the body." Frame bearing steel by stamping, welded together, for the design and manufacture of high technology requirements, which is in China is difficult to break through the body design and development of major difficulties. Forming with the frame is a cockpit, engine compartment and the bottom frame,
We can see the smooth body of the car was embedded in the skeleton on the cover. Bearing-type trailers is the mainstream sedan, which will frame the structure and the two parts of a body, light weight, can make use of a large space, low center of gravity, and press molding methods are very suitable for the manufacture of modern mass production. However, in addition to the development and fabrication of a high degree of difficulty, the stiffness (in particular, torsional rigidity) is less than the body-type carrying a major flaw.
This car is not used in day-to-day obviously, but for the high-powered, large torque, high-performance sports car, the frame requires a high rigidity, general body type bearing stiffness becomes insufficient. Thus in recent years, high-performance car, in addition to continuously upgrade the horsepower, each depot has been committed to improving the stiffness of the body, the current approach taken by the main frame to optimize the geometry and the use of local thickening or repairing the ability to enhance the torsional.
Frame as a result of carrying all the parts will all trucks, including the suspension, body and crew fused with good control response, and transmission of vibration and noise are less beam-type frame which is unparalleled. So not only is the car, and even some road environment for the design of good off-road vehicles also have to switch to disposable beam frame and body-type carrying the trend, and this is the so-called "city of sport utility vehicle."
In addition, beam-type frame to the drawbacks of high. Also emerged in recent years the use of carrying large bus-style body (known as "non-beam body" or "non-array body"), as a result of the abolition of the beam, tourism bus can be released at the end of the car around and run through a huge luggage space, for urban bus platform can be reduced on the sidewalk in order to get off high (to tie in with the purchase of special low-Axle). Low-floor bus is an important direction of development.
Steel tube-type frame in front of said load-type frame design and development and production processes are complex and only suitable for mass production. But for a small number of cars produced by what?
