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.

对于焊工来说这是一个常见的回路，它需要很大的夹力用卸压阀来设置，焊枪上减小的力可通过减压阀来设置。

Encapsulant was driven by capillary force into the space between the chip and substrate. Underfill technique can protect the electrical device and prevent the device from destroying because of external force. Underfill has many defects including the fill time is too long, the situation of short shot and air trap are caused easily, the yield of product of Flip-Chip is not highest and the products are universal. Therefore, there are many factors being studied in this paper to sum up the influence of underfill of Flip-Chip process cause by model parameters.

覆晶接合技术为先进电子讯号连接技术中的一种，具有高I/O数、电子讯号路径短以及尺寸小等优点，而采用覆晶接合之电子元件大部分均以底部充填技术进行封装；底部充填是一种以毛细作用为驱动力在晶片与基板之间的间隙充填底胶的封装技术，可以确保晶片不受到外力的影响而损及封装体，但此技术具有充填时间长、容易产生短射与包风等缺点，使得覆晶封装制程良率不高，间接影响覆晶封装产品的普及率，因此本文将依各种可能之参数模型对覆晶封装底部充填制程的影响，以供业界参考。
