采用高精度的ENO格式和基于基元化学反应的真实化学反应模型求解氢氧混合气体一维爆轰波的精细结构。采用直接起爆方法得到稳定传播的爆轰波，计算的爆轰波阵面参数和实验相当符合。对爆轰波反应区化学反应的研究表明，参与反应的不同组分具有不同类型的变化特征。网格尺寸影响的研究表明，计算结果的精度随着网格尺寸的增加而增加，并能保持较好的收敛性。移动网格研究结果表明，网格运动速度和爆轰速度接近时，两者的相互作用对计算结果产生一定影响。 |

With a high resolution ENO (Essentially Non-oscillatory) scheme and a detailed chemical reaction model, one dimensional detonation wave structure of H_2-O_2 mixture was calculated. The numerical results were good agreement with experimental data. The refined structures of reaction zones were discussed. The effects of grid size and moving grid were investigated. |
