Based on the elastic theory of large deflection and by taking into account the variation of the axial force and its effects on bending deformation of the drillstring in vertical section,the vibration of the drillstring induced by fluctuating weight-on-bit is described by a parametrically excited system.A Mathieu equation describing the system is established by Galerkin Method.By extending the solution into a Fourier series,the curves of dynamic bifurcation values and the dynamically unstable regions surrounded by the curves are presented.

基于弹性大变形理论，考虑到轴力沿钻柱轴线的变化及其对钻柱弯曲变形的影响等因素，将受自重作用的铅垂井段钻柱在波动钻压激励下的振动转化为一个参数激励系统，用Galerkin方法首次得到了描述此系统的Mathieu方程，并通过将方程的解展成富里叶级数的方法，得到了该振动系统的动力分岔值曲线及其所包围的动力不稳定区。

Their Excellencies, the Lords Justices in council, taking into consideration the many inconveniences arising to the public from several projects set on foot for raising of joint stock for various purposes, and that a great many of his Majesty's subjects have been drawn in to part with their money on pretence of assurances that their petitions for patents and charters, to enable them to carry on the same, would be granted: to prevent such impositions, their Excellencies, this day, ordered the said several petitions, together with such reports from the Board of Trade, and from his Majesty's Attorney and Solicitor General, as had been obtained thereon, to be laid before them, and after mature consideration thereof, were pleased, by advice of his Majesty's Privy Council, to order that the said petitions be dismissed, which are as follow

枢密院大法官阁下讨论了那些以各种目的发行股票的项目给公众带来的诸多困扰，注意到许多国王陛下的臣民已经被引诱在这些项目上投入金钱，而他们所得到的保证是完全虚假的，那些项目并没有得到获准实施的专利权和特许状。为了防止类似的欺诈，大法官阁下当日命令将上述项目的申请书，以及此后得到的来自商会、国王陛下的司法大臣（his Majesty's Attorney）和助理司法大臣处的类似报告，一同在他们面前展示。经过反复考虑，并且根据来自国王陛下枢密院的建议，大法官阁下一致同意将上述申请书予以废除，它们的具体名单如下

Mauriac concluded the reasons causing the social phenomenon as loss of God and love in the modern society, meanwhile, he considered God and love as the "spring" in the "desert".

莫里亚克将造成这种社会现象的原因归之为现代社会中上帝与爱的失落，同时，他又把上帝与爱看"荒漠"中的一眼"甘泉"，通过上帝与爱的复归，而使人类得到解脱，灵魂得到救赎。

Based on the analysis of the results of these two cases, the rule of element's σ, at different position is presented, and it shows that the steel panel can effectively reduce the maximal σ, of the element adjacent to the steel panel, and can postpone the arriving time within the simulation time. At the same time, the simulation reveals that the boundary effects don't affect the spalling in the similar structure presented in this paper.

通过对两种情况下的结果分析，揭示了混凝土不同位置处单元σ值的时程规律，得到了在计算时间内钢板的存在能够有效地减小相邻混凝土单元的最大拉应力，并延长其出现时间；同时得到了在类似研究的工程结构中，边界效应对混凝土层裂现象无影响。

In the same way, a Four-coloring of a maximal planar graph of 25 order G(subscript M25), is obtained with "simplified method of reduction of order".

利用"简化降阶法"对一个一定拓扑结构的12阶最大平面图G(下标 M12)进行着色，得到G(下标 M12)的四色着色方案；以同样的方法对一个一定拓扑结构的25阶最大平面图G(下标 M25)进行着色，得到了G(下标 M25)的四色着色方案。

According to the maximum likelihood method inferred, the fatigue test of the incomplete penetration welded joint s was conducted, and the P S N curves were obtained.
