本文推导了参数调节算法，并讨论了器件不理想因子已知与未知两种情况下的消除方法，证明了在器件不理想因子未知情况下采用迭代方法确定的参数最终收敛于不理想因子已知情况下的参数。

To obtain a complete picture about shock formation in non-viscous flow, in the succeeding chapter we investigate the isothermal shocks in adiabatic flows. We find that in this case the shock solution still exists, but the structure and the properties of the solution are greatly different from above even qualitatively. In some region of the parameter space there only exists unstable shock solution and in some region of the parameter space there may exist two stable shock solutions.
