We study cuspidal loop bifurcation、 Homoclinic or double Homoclinic bifurcation、 Hopf bifurcation and obtain the necessary conditions to generate limit cycles by using the coefficients of the expansion of the first Melnikov function.

利用一阶Melnikov函数的展开式的系数研究了尖点环分支、同宿分支、双同宿分支和Hopf分支，并给出了产生极限环的充分条件。

Detailed studies are made as follows: Searching the key internal factors which can affects slope stability. According to the geological data which was gained by exploration investigation, establishing a geological model which can reflect rock mass characteristics;With analyzing the internal and exterior factors synthetically, the deformation and possible failure mechanism and mode of the cut slopes was confirmed which combines with stereoic projection and other techniques;The stabilities of the 14 high slopes are estimated synthetically by applicable design codes and guidelines. With the estimate result and some other analysis methods, the rock mass mechanical parameters of slope are identified;As a results, 14 high slopes fall into 4 categories based on rockmass characteristics and discontinuities. The stability and deformation of some typical slopes was analyzed with distinct element method by UDEC;The safety factor of some dangerous slopes are calculated by rigid limiting equilibrium method for coMParison.

首先着重研究影响边坡稳定性的内在因素，主要是通过地质勘探、测量、现场观测等手段取得研究区地质体的基础地质资料，建立起能够反映地质体结构特征的地质模型；随后综合分析潜在的内外部影响因素，并结合赤平投影对边坡可能的失稳模式或破坏机制作出判断；运用已有岩体质量分类方法对沿线14个高陡边坡稳定性进行初步的评价，并结合试验研究、经验判断、工程类比等手段确定了坡体的岩体力学参数；根据稳定性初步评价结果将研究区14个高陡边坡按开挖方式分为4大类，并利用离散元程序UDEC对各类典型高陡边坡进行了稳定性计算分析；对潜在危险边坡利用刚体极限平衡法求出了不同工况下的安全系数。

他将自己的开支削减到了极限。

Because the kinematically-admissble cyclic strain rate field required in kninematical-type theorem of shakedown analysis is rather difficult to be constructed, shakedown analysis based on kinematcal theorem cannot be directly applied.

在竖向载荷与水平载荷共同作用下，研究了地基土体的强度特性与土层分布特征对地基承载力的彤响，对地基的极限载荷与安定戳荷进行了比较分析，为全面、综合地评价非均质地基的稳定性提供了有益的参考。

We've been stretching our capacities to the limit, and we've been doing our damnedest, but America has still launched over 150 space missions and has watched three of them end in catastrophic failure.

我们拓展自身的能力达到极限，我们也尽了我们最大的努力，可是美国尽管进行了超过150次的太空任务，但要注意到其中有三次以惨痛的失败告终。

I swear to you by him who died for us that naught shall induce me to breathe one syllable to my jailers; but I conjure you do not abandon me. If you do, I swear to you, for I have got to the end of my strength, that I will dash my brains out against the wall, and you will have my death to reproach yourself with.""

我以基督的名义向你发誓，我情愿让他们杀了我也不会向刽子手们吐露一点实情的，看在上帝的份上，别离开，别不和我说话，不然我向你发誓因为我已忍耐到了极限，我会把头在墙上撞碎的，会懊悔的。""

You can internalize the lessons you've learned without toting anymore deadweight around.

你可以吸取以往的教训，把它们变成自己的东西，而不用在心里所能承受的极限上走钢丝。
