中文摘要：

本文建立了一种以温度为单变量进行迭代，求解真实气体模型下的斜爆震波波后参数非线性方程组的方法。并通过以加热量和气流偏转角为变量，计算出对应斜爆震波角度和斜爆震波的驻定范围。对于给定的来流条件，基于真实气体模型的斜爆震波的驻定范围比量热完全气体的宽，所以在斜爆震波的计算中必须考虑热物性的影响。随着氢气和空气化学当量比的增加，斜爆震波驻定范围逐步变小。而来流马赫数越大，斜爆震波的驻定范围越大，其CJ爆震波对应的平面偏转角越小。来流初温的升高则使斜爆震波的驻定范围变宽。斜爆震波的驻定需要来流条件与斜面角度等因素的相互匹配。

英文摘要：

A numerical method of single variable iteration by temperature for solving nonlinear equations of real gas model was developed. Theoretical analysis gives effect of different heat flux and deflection angles of gas on the angle of oblique detonation wave（ODW）. For a given H2-air mixture flow, the standing range of the oblique detonation wave predicted by the real gas model is larger than that by the calorically perfect gas model, this indicates that the thermal property should be considered when calculating an oblique detonation wave. With the equivalence ratio of hydrogen to air increasing, the standing range of the oblique detonation wave is changing small. With the Mach number of oncoming flow increasing, the standing range of the oblique detonation wave increases, and the minimum turning angles of Chapman-Jouguet states decrease. The increased temperature of oncoming flow is beneficial to promote the standing range of the oblique detonation wave. The standing ability of oblique detonation wave relates to the oncoming flow condition and the angle of wedge.
