The combustion events in the swirl chamber and the main chamber are processed differently. The combustion in the swirl chamber is broken into three phases: low temperature ignition, high temperature premixed combustion and flamelet diffusion combustion, while the combustion in the main chamber is only considered as flamelet diffusion combustion. The Shell ignition model, global Arrhenius equation and coherent flamelet model are used to describe low temperature ignition kinetics, high temperature premixed kinetics combustion and flamelet diffusion combustion respectively.

把涡流室式柴油机不同区域与不同时期的燃烧过程分开处理，将涡流室中的燃烧过程划分为三个性质不同但相互重叠的阶段：用Shell着火模型模拟的低温着火化学动力学反应阶段，用Arrhenius方程模拟的高温预混燃烧化学动力学反应阶段和用相关火焰微元模型模拟的扩散燃烧阶段，认为主燃烧室的燃烧只有相关火焰微元的扩散燃烧阶段。

Bonding structure and the change of chemical composition at the Cu/ceramic interface are investigated systematically with microanalysis. Furthermore, it is observed that copper bonding to Al〓O〓 ceramic is formed by chemical reaction between Cu〓O within the Cu-Cu〓O eutectic and Al〓O〓 at high temperature, CuAlO〓 as a reaction result is produced, mechanic join and physical osmose are not the main factor.

运用多种显微分析技术，对铜-陶瓷键合界面的微观结构，以及键合前后物相化学成份的变化，进行了系统的研究，在此基础上，明确了Cu-Al〓O〓陶瓷的键合机理；机械交联和物理渗透不是形成键合的首要因素，键合是通过Cu-Cu〓O共晶熔体中的Cu〓O相在高温下与Al〓O〓陶瓷发生了化学反应，形成了牢固的化学键合，同时伴随有一些CuAlO〓物相的生成。
