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。

Stressing on "fine reputation","quality","service","credit","practice", not only the grandeur.④Encouraging the innovation, not the unearthliness, playing down the effect of entertainment stars or idols, decreasing the fashion index.⑤"personality" is not the "self central". Social sense of responsibility and interpersonal "feeling of affinity" are both intensified.3.1.2 Factor analysis, revealing 19 value element vectors, which include "comfort","personality","simple","fine reputation","responsibility","service","price","wisdom","distinction","enthusiasm","stimulation","taste","sex difference","quality","vigor","idol","fashion","affinity","aesthetic" and so on. Four orientation diagrams coordinated with the average factors and the standard deviations of these 19 value elements, described the multi directional value orientation structure for China college students' sportswear consumption.3.1.3 Clustering analysis are applied to classify the former 19 value elements, which discovered that three inferior group are classified from the college students' consumption group based on the whole specimen data. It could be the reference of enterprise brand building for the orientation of consumption values.3.2 General personal values, self conception and demographic are lead into as three major variables for the interrelationship analysis of sportswear consumption value system.3.2.1 Firstly, the college students having their general values and existing the inferior group feature regarding to the consumption values.

三、研究的主要成果及其意义对中国大学生休闲服消费价值体系进行探索性分析1、首先对中国大学生休闲服消费价值观量化问卷所调查的样本数据进行频数统计趋向性分析，发现呈现的主要特点有：(1)"个性化"和"简约"已成为潮流，而寻"刺激"、找"激情"总体收敛；(2)追求"美感"，更不放弃"舒适"，两者兼得才是完美；(3)重"美誉"、讲"质量"，重"服务"、讲"信用"，求实际、不求高贵，"明智"有素；(4)求新不求怪异，明星、偶像效应淡化、时尚指数不高；(5)"个性化"不是"唯我化"，社会责任感和人际"亲和力"在强化。2、其次对样本数据进行因子分析，揭示出以"舒适"、"个性"、"简约"、"美誉"、"责任"、"服务"、"价格"、"明智"、"独特"、"激情"、"刺激"、"品位"、"性差"、"质量"、"活力"、"偶像"、"时尚"、"亲和"和"美感"等十九个价值元素为矢量的休闲服消费价值体系，并以因子均值和标准差为参数勾画出19个价值元素坐标四方位图，从总体上描述了中国大学生休闲服消费多维的价值取向结构。3、再者进行聚类分析，对上述十九个休闲服消费价值元素作不同量值的分类，发现在样本总量中可以细分为有较大区分度的三个类别，呈现出大学生消费群体中存在休闲服消费价值体系不同的亚群体，可为以消费价值观为取向的企业品牌价值定位提供参考基谱。

The result shows that these;proteins showed some similarity with known proteins in the database. They may have function in the resistance responses to Verticillium wilt.
