In this paper the nonstationary vibration behavior of an unbalanced rotor system, which is assumed to be bending flexible but torsionally rigid, during acceleration or deceleration through the critical speeds is investigated. Influencing factors such as gyrascopic effects, external and internal damping, Supporting mass, damping and stiffness, asymmetry of the shaft crass section as well as anisotropy of the supports are considered.

在理论分析方面，本文考虑了转子的陀螺效应，内外阻尼，轴截面的非对称性，支承的貭量、阻尼、刚度和支承的各向异性等因素的影响，使用分析动力学，建立起严格的运动方程，并考虑了弯曲自由度与转动自由度间的耦合，因而能较精确地分析和描述转子通过临界点时的非定常振动和转速变化規律。

It enables NASA to create the operating conditions for large transport aircraft flying at transonic speeds of up to 1,440 kilometers per hour.

它使得NASA可以为大型运输航天飞机创造出运行条件，以每小时1，440公里的跨音速飞行。

For the specific site, it shall be checked whether the wind speeds and the turb ulence intensity, including local turbulence magnification as a result of the influence s of adjacent structure e.g.

3对于风场，应检查风速和湍流强度，包括局部湍流的数量级，这些局部湍流强度由于邻近机组的影响而增强，检查是否符合以计算为基础的假定。

As the turbomachine is designed to operate at higher speeds, the stability of the rotor system becomes more sever.

透平机械转子动力系统的运动稳定性问题是目前转子动力学中的一个热点课题。

All premium member servers are uncapped for best speeds.

所有保费是国家队成员服务器的最佳速度。

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。

The failure of charge policy on the price of real estate speeds up the rise of house price, aggravates those middle-low income group's shoulder, restrains the development of other industries, results in the unbalance between economy structure and social structure, invites new unjustness on social distribution, contuses the enthusiasm of labours badly, brings profound social problems, and even induces the breakout of finance crisis, presenting a mass of bad debts towards finance organization, all of which make the whole country economy be in hot water.

房地产价格调控政策的失灵，使住房价格上涨过快，加重了中低收入人群的负担，抑制其他产业的发展，导致经济结构和社会结构的失衡，招致社会分配新的不公，严重挫伤劳动者对策积极性，带来了深刻的社会问题，甚至会导致金融危机的爆发，给金融机构带来大量的呆账和坏账，使整个国民经济陷入困境。

The possibility of using a reaction jet had interested aircraft designers for a long time, but initially the low speeds of early aircraft and the unsuitably of a piston engine for producing the large high velocity airflow necessary for the jet presented

使用反作用喷气的可能性令飞机设计师们向往已久，但在最初存在很多障碍，这是因为早期飞机的速度很低和活塞发动机不适合于产生&喷气式&所必需的大量高速气流。

This, says Vishal Sikka, the firm's chief technologist, not only speeds up existing programs—it also makes them cheaper to run and easier to upgrade, and makes possible real-time monitoring of a firm's performance.

该公司的首席工程师称，这种方式不仅能加速运行现有程序，同时降低了运行成本并简化了升级过程。此外，实时监测整个公司的运转情况也因此成为了可能。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
