A new study idea that makes the occupant injury prevention research and CAD/CAE technology on an integrate mathematical model by means of feature theories and feature design technologies was brought, and it is maybe useful if we study automobile passive safety on a new view of point.The conclusions of this thesis included that what are the main factors of airbag-related injuries and the preventive measures, based on the research of the relationships between injury parameters, such as HIC, chest acceleration, neck force, neck moment, femur axial force etc, and impact speed, belt-use, occupant size (50th and 5th), sitting position and so on. The thesis evaluated whether the effectiveness of the airbag can be increased by making the airbag adaptive to the crash conditions, and points out that the size of the ventilation hole has the dominating influence on the performance of the airbag and is a key factor for intelligent airbag, multi-stage and lower-power inflator can cost effectively minimize the risk of injury to occupants from crashes. It is important for the researchers of intelligent airbag to keep the small size unbelted occupants in focus and it is necessary to study deeply the influence of airbag fold patterns and the extremity out-of-position situation. These topics are important in the study of occupant injury prevention and vehicle safety design.

论文研究得出产生气囊损伤的主要原因和防护措施；在研究汽车碰撞速度、安全带使用情况、乘员的体型5~(th和50~、乘员乘坐的位置等不同事故条件作用下，乘员的头部、颈部、胸部和腿部损伤参数变化规律的基础上，论文从能量因素出发，深入研究了安全气囊卸载能力、气体发生器产气能力和气囊折叠对乘员损伤参数的影响，指出起卸载作用的排气孔其截面积是智能型安全气囊最重要的控制参数之一，以及采用降能展开或二次充气气囊有助于提高汽车安全防护性等重要结论；论文在参数分析的基严内容提要2 础上得出的智能型安全气囊应以不佩戴安全带的5乘员作为主要防护目标进行研究、有必要深入研究气囊折叠形式和司机处于极端离位状况时对损伤参数的影响等结论，对深入进行汽车乘员碰撞损伤研究和汽车安全性设计都具有重要的理论和工程实际意义。

These factors have seriously influenced the security and economical operation of the unit. This paper firstly summarizes the research background and the general situation of resarch about the overheating problem of boiler's high-temperature surface ,introduces the aspects and research findings in this field such as flux deviation、thermal deviation、flue gas velocity deviation at the exit of furnace and tee bends,et al.Then analyses the reason why high-temperature surfaces are overheated from such aspects as design、manufacture、operation, et al and points out one of the main factors that cause the overheating of reheaters is the flue gas velocity deviation caused by the remaining turning at the exit of furnace.
