快速安全提高汽轮发电机转子检修质量。。。摘要：针对用户对负载供电不间断的实际需求，分析了数码发电机的内部结构及其不能实现供电的不间断性能的原因，提出一种由数码发电机改造组成的交流不间断供电系统的设计方法。该设计利用发电机内部的逆变器，在市电正常时，由市电经过逆变器给负载供电，同时给蓄电池充电；在市电断电时，一边启动发电机，一边由蓄电池的直流电通过逆变器转换成交流电供负载使用，实现无论市电正常还是异常，系统对负载提供不间断电源。设计对市电进行稳压、稳频、输出零切换、蓄电池的充放电管理等新功能。此设计无需单独购买不间断电源，避免重复投资和资源浪费。

The theory of accretion disks are important for many astrophysical phenomena, including Quasars, active galatic nucleic, X-ray binary stars, and young stellar objects. The most important branch of accretion djsk theory is the stability properties of djsks. It is widely considered that the luminosity variations of various astronomical objects are associated with the instability of accretion disk. The viscosity plays an important role in the accretion disk theory, and magnetic field exists commonly in astronomical phenomena. A more realistic analysis of the stabihty of the accretion disk should include both the radjal and azimuthal perturbations because of the strong shear of viscous flow.In this paper, according to the luminosity Variations of Various astronomical objects, we study the radial-azimuthal instability of an isothermal with magnetic field. We find that the radial and azimuthal fields B〓,B〓 are mainly responsible for enhancing the instability of the magneto-acoustic modes and non-axisymmetric modes,and that pulsational oscillations are larger in the radial than in the Z direction. The model may be useful in explaining the periodic light variation of FU orionis and. T Tauri stars.

在许多天体物理现象中，例如活动星系核，X-射线双星和年青的恒星理论中，吸积盘理论起着重要的作用，而吸积盘理论中的一个重要分支是吸积盘的不稳定性理论，普遍认为活动天体的周期，准周期光变现象与吸积盘的不稳定性有关，在吸积盘理论中，粘滞起着重要的作用，而磁场是天体物理中普遍存在的现象，对于几何薄吸积盘不稳定性分析，由于强剪切流的缘故，应该包括径向和环向扰动两个方面，本文结合天体物理中的各种周期，准周期光变现象，研究了含磁场的等温薄吸积盘的径向-环向振荡不稳定性，结果表明：磁场的径向和环向分量对磁声模和非轴对称模的不稳定性的增加起着主要的作用，且径向振荡大于轴向振荡，所得结果有利于解释FU Orionis和T Tauri Stars的周期光变现象。

We were puzzled and lost orientation as we were surfing the minefield tianyaforum,tremblingly as the ground we stood shaken.coexisted with the faith and fraud,tangled the right and the mean,accompanyed the beauty and the ugliness.it was the season that setted off the adulthood childish.the cub sophisticated,the kindhearted nonchalance ,and the nonchalant filled with compassion ,we were always full of tears in eyes while turned down disdain look were around our face.

这个秋天我们来到天涯，一下子迷糊了双眼，迷失了方向。我们站立的地面在摇晃，在颤抖。真实和虚伪并存，正义和邪恶交织，美丽与丑陋相伴。这个秋天使成熟的人变得幼稚，使那些原本幼稚的人变得老练。使心存善意的人变得冷酷无情，使原本冷酷无情的人动了恻隐之心。这个怪异的秋天总使我们眼角噙满眼泪，同时又使我们嘴角布满讥诮。
