固体推进剂燃烧 meaning in English

solid-propellant combustion

Numerical simulation of deflagration - to - detonation transition in high energy propellant
高能固体推进剂燃烧转爆轰的数值模拟
The chemical reactions in the flame area are very complex . it is very difficult to measure the number density distribution of the particles ( atoms , ions and molecules ) , so the relative intensity method is employed
由于固体推进剂燃烧区内发生的化学反应非常复杂,直接测量火焰区内的粒子(原子、离子以及分子等)数密度比较困难,因此选用相对强度法来进行计算。
Level set method was used in this paper to attain burning surface variety regulation of arbitrary configuration grain by tracing interface of grain surface burnback . the work of this thesis can be summaried as follow : 1
