| 摘要: |
| 利用一维定常流理论，建立了超声速引射器中从混合段到扩压器出口的冷气流混合模型。经过计算，得到了在不同的输入条件下，等面积混合模型和等压混合模型的恢复压力。比较结果，发现等压混合并不总是优于等面积混合，并得出了判断等面积混合与等压混合优劣的条件。在更改参考文献中的部分输入参数后，得出了同样的结论。 |

| Abstract: |
| The one-dimension mixing model is established from steady state theory, thus the recovery pressures of constant-area mixing model and constant-pressure mixing model are attained. The result implies that the performance of constant-pressure mixing is not always better than that of constant-area mixing, so a criterion is established to estimate the better one of the two mixing models. The consistent conclusion is attained by altering some of the initial parameters in reference. |
