These results in the chapter two are on the basis of theocratical analysis and numerical simulations such as condition for SNB and Hopf bifurcation, bifurcation diagram, trajectories, Lyapunov exponent, Floquet multipliers, dimension of attractor and so on.

本章的结论是根据理论分析和数值模拟的结果，这包括给出SNB和Hopf分支条件，分支图，轨线模拟，Floquet乘子的计算，Lyapunov指数和吸引子的维数的计算等。

It is shown that the direction of bifurcation and the stability of the bifurcating periodic solutions of the Euler methods are the same as the direction of bifurcation and the stability of the bifurcating periodic solutions of the original delay differential equation when the stepsize is small enough.

证明当步长充分小时数值Hopf分支的分支方向、分支周期解的稳定性与原方程的Hopf分支的分支方向、分支周期解的稳定性相同。

A muscle-equivalent phantom was used to instead of liver tissue in the experiment. The liver artery of human was simulated by a copper tube with Y bifurcation. Different water flow velocities were maintained in the tube, which are in the typical range of blood flow velocities in liver arteries of human. Copper-constantan thermocouples were used to measure the temperature near the arterial bifurcation.

实验采用一种等效微波体模来代替肝组织；采用Y型铜管代替人体肝动脉内的分叉大血管，并依据人体肝动脉的血流速度调节管内的水流速度；利用铜-康铜热电偶测量分叉血管周围的温度场。

Moreover, each of their exact correspondingentropy is obtained via the method of transition matrices. We also study the bifurcation phenomenon of mosaic patterns with bifurcation parameters z and β. Here z is a source term and β is the interaction weight between the neighboring cells.

Also the normal form and thediagram of the Hopf bifurcation are deduced with the normal form direct method.Secondly, the influences of the physical and aerodynamic parameter on the type of theHopf bifurcation are analyzed. Study shows that the "hard" structural non-linearitiesand the longer distance of the suspension point and the center of mass render theairfoil safer, whereas the "soft" ones render the airfoil more unsafe.

同样应用规范型直接法，研究得出系统颤振的Hopf分岔解的规范型以及分岔图；其次，研究了系统结构和气动参数对Hopf分岔类型的影响，结果表明，表明具有&硬&弹簧性质的结构及增大悬挂点与质心的距离都有助于提高安全性，而应该避免应用&软&弹簧性质的结构。
