Results show that, under the conditions depicted in this paper, generation rates of characteristic products don't speed up with increase of samples' initial aging degrees, but are consistent with the change of bond scission rate of cellulose. When samples are in mid-end life and aged further, the generation rate decreases almost exponentially.

结果表明：在该文的试验条件下，处于老化中后期的油纸绝缘，在后期继续老化过程中特征产物的生成速率随油纸绝缘初始老化程度的增加并不呈现递增趋势，而是成近似指数递减关系，这与纤维素绝缘纸降解过程中断键速率的变化一致。

Insulation: Given the elaborate surround-sound systems available for home theaters, the proper insulation of walls and ceilings is crucial, not only for those in the room who want to enjoy the movie-theater experience, but also for those in other rooms of the house who aren't interested in catching today's feature presentation.

绝缘材料：假使精心制作的立体声系统可利用为家庭影院，墙壁的适当的绝缘材料和天花板是关键的，不仅为想要享受电影剧院经验的那些在屋子里，而且为那些在不是对传染性的今天特点介绍感兴趣房子的其他屋子里。

The four sets of stator bars including those retired from three large generators and the standby bar subjected to Dynamic Mechanical Analysis, Scanning Electron Microscopic and optical microscope observation. It was revealed from DMA that the peak value tan d m of mechanical loss thermogram tan d ~ T shift toward a higher temperature and a lower amplitude, indicating that the amount of movement monomers diminished greatly in the insulation aging process, the tan d 195, increased very slightly with the service time of insulation, showing the degrading of bonding properties at interface, and the presence of more defects in insulation. The observation of SEM and optical microscope showed that more and more voids appears in insulation, and delamination was formed due to development of voids in aging process.

对不同运行年数的线棒进行了 DMA 、 SEM 、光学显微镜等微观分析试验，动态力学分析发现(参见 Hao et al， CEIDP， 2002：404)，力学损耗温度谱 tan d ~ T 的峰值 tan d m 随老化时间向高温、低值方向移动，表明促成环氧发生玻璃化转变的活性侧基或发生局部运动的活性链段减少，分子链的刚性增强；195℃的力学损耗 tan d 195随老化时间有缓慢增大的趋势，表明有更多的能量耗散在界面处，界面的粘合性变差，甚至由于界面粘结不良出现微观缺陷； SEM 和光学显微分析发现(参见 Hao et al-2， IEEE DEI， 2003)，老化后的绝缘气隙增多，随着老化时间气隙不断扩展或相互连通，绝缘逐渐分层。

The GIS gray intensity images were constructed based on mass discharge specimens gathered by the ultra-high frequency and high speeds systems.

1引言气体绝缘组合电器具有绝缘强度高、运行稳定、占地面积少和维护工作量小等优点，在大中城市电网中得到广泛应用。

Mathematics model of dielectric under uniform electric field is built up, and total current is separated into three parts such as conductive current, instantaneous current and relaxation polarization current, then polarization and depolarization of linear and non-linear dielectric are simulated under step excitation, the results show that nonlinearity of non-linear conductivity is reflected by measuring surface potential attenuation during the process of self-discharge of non-linear dielectric.

论文首先对处于均匀电场下的电介质进行电路建模，把电介质的总电流分为电导电流、位移极化电流和松弛极化电流三部分来分析，然后以此为基础利用Matlab软件中的Simulink平台对直流阶跃激励下线性和非线性绝缘介质的极化和退极化过程进行了仿真，结果表明可以通过测试非线性绝缘介质自放电过程的表面电位衰减来反映其非线性电导的非线性程度信息。

By much expriment, this thesis discovers the the vacuation of whole cable insulation can be replaced by that of polymer particles. Then cable insulation is immpregnated by filling SF〓 into cable core.

本文经过大量对比和模拟实验发现，粒料的抽真空浸渍可以代替电缆绝缘的抽真空过程，由于粒料体积小，其抽真空浸渍容易完成；然后再在电缆线芯充SF〓气体对电缆绝缘进行浸渍。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
