Although Pulsatilla can easily be distinguished from Anemone by the former having a long, plumose beak on the achenes formed by the persistent style, phylogenetic studies have shown that they are probably congeneric.

The phylogeny of the genus Machilus was analysed by means of Bayesian Inference of nrDNA ITS sequences . Our results indicated that Machilus is a monophyletic clade within the Persea group, and its persistent and spreading to reflexed tepals on fruit are an important character for its generic delimitation against the related genera Phoebe, Alseodaphne and Persea .

In chapter five,we discuss the problem whether the mid-point scheme can inheritthe homoclinic orbit of S-symmetric systems.

第五章討論S-對稱系統(tǒng)的中點(diǎn)格式對于同宿軌的繼承性問題。

Moreover,in this dissertation,a method ispresented to control safe basin with the fractal erosion,that is by the application ofthe weak parameter periodic perturbation with an optimal frequency to control thefractal erosion basin,and the analytical study shows that the essence of the methodis that the parameter periodic perturbation can be used to delay the occurrence ofhomoclinic tangencies.

并且在本文提出了一種對分形侵蝕安全域進(jìn)行控制的方法国产欧洲aaa，那就是應(yīng)用具有最優(yōu)頻率的參數(shù)周期擾動對于已受到分形侵蝕的安全域加以控制欧美乐播视频，在理論分析中得到這種控制分形侵蝕安全域的方法實(shí)質(zhì)上延緩了鞍點(diǎn)同宿相切的發(fā)生，同時考慮了外加噪聲對控制后安全域的影響欧美大泬，得到這種控制方法具有很好的魯棒性久久久精品久久久。

Chapter 4 is devoted to the existence and multiplicity of homoclinic for self-adjoint nonlinear second order difference equations by using "Mountain Pass " theorem and "Symmetry Mountain Pass "theorem in critical point theory.

When discussing the bifurcation of subharmonics orbits, many papers need a samilar assumption of the monotonicity of periodic orbits near the homoclinic orbit.
