In the process of investigation, it is assumed that gas flow through the exhaust diffusers is of one dimensional quasi-steady incompressible flow.
在研究过程中，假定排气扩压器的气流为一元准稳定不可压缩气流，试验装置采用压缩气源供气。
This paper points out that the thermal and ablative problems of the shield can be solved solely with the coolant flow only under one-dimensional incompressible or steady condition.
在冷却剂渗流是一维不可压缩的（或一维定常的）条件下，热层的传热和烧蚀问题可以单独求解。
Thus, Eqs. (8.2), (8.6), (8.10) are governing equations for one-dimensional, steady, adiabatic, inviscid flow.
因此，方程(8.2)，(8.6)，(8.10)是一维、定常、绝热、无粘流动的控制方程。
