We now study the same problem for the incompressible materials .
现在我们对于不可压缩的材料来研究同样的问题。
We frequently regard gases as compressible , liquids as incompressible .
我们通常认为气体是可压缩的,液体是不可压缩的。
Gases are frequently regarded as compressible , liquids as incompressible .
人们通常认为气体是可压缩的,而液体是不可压缩的。
For incompressible fluids , both the mass flux and the volume flux are constant in a tube of flow .
对于不可压缩的流体来说,流管中的质量通量和体积通量都是恒定不变的。
These dramatic curlicues were generated by a computer simulation of the motion of a small body - in this case a flat , rigid plate - through an incompressible fluid , such as water or , in some conditions , air .
