中文摘要:
      通过理想流体定常流动的理论解析,导出了微马赫数下密度的相对变化率与压强、温度的相对变化率的关系式,得到了当M<<1时的低速气体流动问题可视作不可压缩来处理的直观理论解析.
英文摘要:
      The relationship between the variation of density and the variations of pressure and temperature is educed under micro-Mach number by the theoretical analysis on the steady flow of ideal fluid,and the theoretical analysis of the incompressibility of low-speed gas flow is obtained when the flow is treated as an incompressible flow with M<<1.
