Its remoteness, quietness, vacancy, pleasantness, elegance, coziness, enjoyment, comfort and broad-mindedness, not only stay on the aesthetic experience, but also maintain as a dynamic and rational comprehension, embodying a kind of desire which is the conqueror's ambition; however, such a beauty can never be obtained by the current p

其高远、悠静、空澄、恬美、优雅、畅怀、悦目、舒心、旷达的审美感受，不只是停留在审美体验上，而是一种动态的理性感悟，有一种渴望，征服者的欲望，而这种美，决不是臆测的当今柴窑瓷器所能达到的，只有神垕的钧瓷时稳时现地放射出这种美丽的光芒。

Its remoteness, quietness, vacancy, pleasantness, elegance, coziness, enjoyment, comfort and broad-mindedness, not only stay on the aesthetic experience, but also maintain as a dynamic and rational comprehension, embodying a kind of desire which is the conqueror's ambition; however, such a beauty can never be obtained by the current porcelains made by kilns in Chai Dynasty as supposed, while only the Jun porcelain produced in Shenhou, can shed this beautiful rays of light in a looming way.

Firstly, the author establish the functions of stability on the basis of the spline function method ,according to the theory of geometrical nonlinear and the theory of stability, educe the stability equation of structure based on variational principle, then carry through the flexuosity analysis of CFST arch.The big distortion geometrical nonlinear was considered by the stability equation,the author simplified the problem of geometrical nonlinear through ignored quadratic term and reserve the simple term, at last boiled down to solve the linear stability equation of eigenvalue .

利用样条函数方法、根据几何非线性变形理论和结构稳定性理论，先建立起结构稳定的泛函，再由变分原理导出结构的稳定方程，进行钢管混凝土拱屈曲分析；本文所建立的稳定方程考虑了几何非线性的大变形效应，通过忽略几何非线性的二次项，保留一次项，将几何非线性问题简化，最后归结为求解线性稳定问题的特征值稳定方程，建立了结构非线性静力稳定性问题的新算法及失稳类型判别准则。

Then steady forced vibration of the nonlinear Disk spring-mass system under base excitation and force excitation is obtained individually by using the Fourier series analysis and harmonic balance method.

详细探讨了考虑静力载荷影响的、具有弹性非线性和Coulomb摩擦阻尼非线性的碟簧元件的建模和动力学特性，首先利用Fourier级数分析技巧和平均法研究了非线性碟簧-质量系统的自由振动，讨论了影响自由振动的振幅和频率的各种因素，然后利用Fourier级数分析技巧和谐波平衡法研究了地基激励和力激励下非线性碟簧-质量系统的强迫振动，通过详细的参数研究考察了非线性碟簧元件的减振性能特征，最后采用修正的稳定性分析方法研究了两种激励下稳态响应的稳定性。

In the system of high precision and low speed, Because of the existence of the nonlinear friction, the static and dynamic performance of the servo system is very bad, such as stick slip, hunting, large error and so on, Because the traditional control of PID is hard to solve the nonlinear problem of the servo system, so this paper begins to introduce a new control method which is named adaptive fuzzy PID, It utilizes the rule of the fuzzy control to adjust the parameter of proportion, integral and differential on line, So this control method has some intelligence to improve the static and dynamic performance of the servo system.

在高精度、超低速伺服系统中，由于非线性摩擦环节的存在，使系统的动态及静态性能受到很大程度的影响，主要表现为低速时出现爬行现象，稳态时有较大的静差或出现极限环振荡；由于传统的PID 控制很难解决伺服系统中的非线性问题，因而不能适用于高精度、超低速伺服系统；本文通过引入模糊自适应整定PID控制，利用模糊规则在线调整比例、积分、微分环节，使系统具有一定的智能，从而非常明显的改善伺服系统的静态及动态性能。

As a result of too fast, so that even Mawei also float up, then sit tight in the messenger on horseback, making the whole lot of moving images in static, reflecting the fast pace of the post horse courier business and skilled, the real and freehand lively and vivid way, the art of painting has always had a far-reaching consequences.

由于速度太快，以至于连马尾也飘了起来，信使则稳坐马背，使得整幅画面动中有静，反衬了驿马速度的快捷与信使业务的熟练，这种真实而又写意、生动传神的手法，对历来的绘画艺术产生了深远的影响。

The rub-impact between rotor and stator often occurs because the rotor shaft stiffness decreases following the occurrence of the crack in the rotor shaft, and thus the coupling fault with rub-impact and crack is hackneyed fault type. Based on the nonlinear dynamical model of the cracked rotor-bearing system with rub-impact, the stability of the periodic motion and instability way were studied in unbalance-rotating speed plane and rotor/stator clearance- rotating speed plane and crack depth- rotating speed plane, and the main results were validated by the experiment.

转子轴承系统裂纹故障的出现会引起转子系统转静件之间碰摩故障的发生，因此裂纹碰摩耦合故障也是转子系统常见的故障类型，本文在裂纹碰摩耦合故障转子轴承系统的非线性动力学模型基础上，分析了系统在不平衡量-转速、碰摩间隙-转速、裂纹深度-转速等参数域内，周期运动的稳定性及其失稳规律，并用实验验证了主要理论结果。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
