Moreover, all signals in the closed-loop system are guaranteed to be semi-globally uniformly ultimately bounded, and the tracking errors are proved to converge to a small residual set around the origin.

保证了闭环系统所有信号半全局一致最终有界，证明了跟踪误差收敛于一个包含原点的小残集。

By integrated Lyapunov stability analysis, it is guaranteed that all of the closed-loop signals are bounded, and the tracking errors converge exponentially to a residual set, whose size can be adjusted by changing the design parameters.

藉由完备的李雅普诺夫稳定度分析，证明所有闭回路信号是有界的，且追踪误差至少可指数收敛至一残局，其大小可藉由调整参数任意控制。

A filtered transformation and a stochastic control Lyapunov design method are applied to Marino-Tomei systems driven by Wiener noises of unknown covariance. A parameter adaptive law and a control law are obtained to ensure that the closed-up systems are noise-to-state stable and the tracking error can converge to a small residual set around the origin in the sense of mean quartic value in average.

通过滤波变换，采用随机控制Lyapunov设计方法，对于受方差未知的Wiener噪声干扰的Marino-Tomei非线性系统，给出了参数自适应律和控制律，使得闭环系统成为噪声--状态稳定的，并且跟踪误差的4次均方值在时间平均意义下收敛到一个足够小的区域内。

In order to study the numerical method to solve the viscous incompressible flow with free surface, the 3-D mathematical model for steady and unsteady hydrodynamic problem had been established and closed by k-εbuoyant turbulence model. The algebraic coordinate transformation method was used to fit the free surface, the Runge-Kutta method of three step and second precision was devised to simulate the time step. A high precision up-winding compact scheme was studied for the convection term, and the generalized conjugate residual method was set to solve the Poisson equation.

为了研究粘性不可压缩三维问题的数值求解方法，本文从基本的Navier-Stokes方程出发，采用代数拟合方法处理自由表面，用三级二阶Runge-Kutta方法对时间步进过程进行了模拟，并且对对流项的高精度迎风格式进行了研究，给出了求解压力Poisson方程的广义共轭剩余法，从而建立了能够模拟有自由表面的粘性不可压缩问题的定常、非定常三维水动力学模型，并采用k—ε浮湍流模型对其进行封闭。

So, it's the way to set the full-closed limit position of the electric actuator.

这样就设定好了执行器全关时电器限位的位置。

Author's aestheticism, Hemingway was managed a traceless writing skill under the rigid discipline, he meticulously described character's behavior in his book, such as prepared for sailing, how to set the bait, how to deal with fish after it fell in to the trap, and eventually how to kill the fish and bind it at shipside, and the plot of whole fighting with the shark was inseparably closed and traceless.

作者的唯美主义，海明威在严格的训练中练就了不落痕迹的写作手法，他在小说中细致的描写了人物行动，诸如出海前的准备，出海后如何下饵，鱼上钩后如何跟它周旋，最后如何把它杀死绑在船边以及和一条条鲨鱼搏斗的整个过程都写的丝丝入扣，不露修饰痕迹。

The solution for the non-stationary system is obtained through the stationary disturbed system. The gradients of the system performances to all design variables are derived and they can be used to obtain optimal solution of the systems. More generally, if the performance of the system is a function of the solution of a set of generalized Lyapunov equation, then the gradients of the performance function to the coefficient matrices of the equation can be found in closed form.

文中显示，非静态干扰系统的解可由静态干扰系统求得，而此干扰系统之最佳解，则经由本文所推导的对所有设计变数之系统性能函数梯度获得；一般而言，如果系统之性能函数是一组通式化 Lyapunov 方程式解的函数，则此方程式的系数矩阵之性能函数梯度，可用封闭解表示之。

However, with today's financial crunch is steep and high pressure to launch a series of land policy and now these "heretical" has been closed almost all of .8 31, all land must be linked into the trick shot; national moratorium on the approval of agricultural land to six months non-agricultural construction land; development zone approved by the investigation and stopped; not paid land transfer payments not only permit but even the land can not get pre-sale licenses are never expect; banks to stop lending or even the second set of residential land and house mortgage loans have been suspended …… it seems the real estate industry in China overnight back in 1993 to "liberate" before the macro-control period, what inflection point theory, and even the collapse of the winter will have on the spondee!

然而，今天的金融危机是陡峭的高压推出了一系列的土地政策，目前这些"邪教"已关闭几乎所有的0.8月31日，所有土地必须联系到把戏杆；国家暂停核准农业用地6个月非农业建设用地；开发区批准的调查和制止；没有支付土地出让金不仅允许，甚至土地不能获得预售许可证从未期望；银行停止贷款，甚至是第二套住宅用地和住房抵押贷款已经暂停……看来，房地产行业在中国一夜之间回到1993年的"解放"前的宏观调控时期，什么拐点理论，甚至崩溃的冬天将会对扬扬格！

By the definition of Vague values——the elements in the closed subinterval set of the unit interval [0,1],some new definitions of binary Vague relations,operations of relations,inverse relations,compositional operations and λ-cut relations are introduced.

通过对单位区间[0，1]的闭子区间集中的元素——Vague值的定义，引入二元Vague关系、关系运算、逆关系、关系的合成、λ-截关系等新的定义。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
