摘要：

The behaviour of steady transonic dense gas flow is essentially governed by two non- dimensional parameters characterising the magnitude and sign of the fundamental derivative of gas dynamics (Gamma) and its derivative with respect to the density at constant entropy (Lambda) in the small-disturbance limit. The resulting response to external forcing is surprisingly rich and studied in detail for the canonical problem of two-dimensional flow past compression/expansion ramps.
