一类可压缩流的马赫数极限。

A class of compressible flow Mach number limit.

如同不可压流动，在可压缩流动中旋涡同样具有场与物质两重特征。

As in the incompressible flow, the Field and Matter Bicharacteristics of Vortex also have been demonstrated.

书针对化学工程应用，并且从而这热局限于是可压缩的流动（低的马赫数）。

The book is aimed at chemical engineering applications, and consequently it is limited to thermally compressible flows ( low Mach numbers).

作为一个组织，多层面料的优点是无效体积大在非可压缩八德结构中。

As a group, multiplayer fabrics have the advantage of a large void volume in the non-compressible bade structure.

在临界温度以上和高压下，蒸汽密度可能变得象在低温下液体那样稠密且不可压缩。

Above the critical temperature and under high pressure the vapor may become as dens and as incompressible as the liquid at lower temperature.
