在分析工作状态下转子圆盘受力的基础上，将拉筋对圆盘的作用分别简化成环形均布载荷和集中载荷，建立承压圆盘的轴对称模型和非轴对称模型，并根据薄板的小挠度弯曲理论，对力学模型进行求解。

The solution of some practical problems in engineering can be regarded as that of periodic solution of nonlinear autonomous systems according to the opinion of mathematics, The problems of this kind are analysed by means of the direct numerical method in this paper,The simple and convenient Draw Newton Method is applied for solving the parameter vectors in iteration course along with the calculation of a practical engineering problem.

日I崖旨J，'口工程中的一些实际问题往往可以归结为非线性自治系统，例如描述同步发电机暂态稳定性问题的转子摇摆方程，即是一典型的非线性自治系统。虽然可以用各种小参数摄动法求解非线性系统，但是这类方法是依据对线性系统的解进行"摄动"来逼近非线性系统解的。因而当系统

The influences of system paramete rs, such as external damping, fluid fill ratio, on the instability of the rotor system are analysed.

准三维无粘流体模型与其它的无粘模型一样也仅能用来分析无外阻尼或外阻尼较小的部分充液转子系统的稳定性问题

Well, if you were to gang together multiple rotors (or use ganged multi polled rotors) you would have a great deal of energy that would be available for a relatively small expenditure.

好吧，如果你来一起团伙多转子，你将有很大的能量，将可为相对小的开支。

At the grid frequency. As the rotor turns near this speed, the voltage induced by this flux is small.

由于转子附近轮流这样的速度，电压引起的这一变化很小。

SiC ceramic has been extensively applied in precision bearings, sealing element, steam-turbine rotor, burner nozzle, heat interchanger parts, atomic reactor materials and etc. because of its excellent properties in high temperature mechanical properties, antioxidatio, abrasion resistance, thermal stability, smaller coefficient of thermal expansion, larger thermal conductivity, hardness, thermal shock and chemical corrosion.
