Based on mass conservation, momentum conservation and energy conservation, physical and correspondent mathematical models were set up to simulate the process of typical explosion of the flat-bottomed and concave-bottomed detonators. Moreover, the simulation results of such two types detonators were compared with each other. The results are valuable for the further study of the detonation process.

讨论了化学放热系统热平衡问题，提出了系统平衡域和平衡度的新概念。分析了经典热爆炸问题的平衡域，并举例说明了利用平衡度定量评价具有热爆炸可能性的系统潜在危险性的方法。文中还讨论了平衡域和平衡度概念对其它研究领域的借鉴意义，提出了用平衡度评估系统平衡性质的一般性思路。

The manganin piezoresistors was used to measure the detonation pressure at different cross sections inside the detonator. Some modifications were made to the traditional detonation pressure measurement device, and the results are significant for further studying the detonation development process as well as for the parameter design and performance analysis of the detonator. It is shown that there are necessity and possibility to further optimize the structure of detonator.
