Results revealed that the large side insulation of the stator bar in slot is available for ultrasonic pulse-echo testing; Coupling transducer on the surface of a practical stator bar could minimize the influence on the measurements of velocity, contributing no destructivity of the ultrasonic testing for stator insulation; The simultaneity of same velocity and higher attenuation can be used to detect insulation delamination from conductors; Compared with the wide sides of the bars in slot, the short sides of the bars near the exit from slot and the end bars had a same velocity and a higher attenuation; The velocity might be exactly measured on the shot sides of the bars near the exit from slot and the end bars, while the attenuation might not, which were examined though filed tests; V min decreased greatly and V av decreased slightly with the service time of the bars.

在实验室对线棒多种结构处的主绝缘和不同运行年数(未老化、16、18 和23年)线棒的主绝缘进行了低频超声反射法检测试验，并进行了现场试验，发现(参见 Hao et al， IEEE DEI， to be published)，槽部线棒的宽面绝缘不受换位绝缘的影响，比窄面绝缘更适合超声测量；线棒表面平滑的半导体层减小了耦合剂对超声测量的影响，实现了无损性；波速不变而声衰减减小可以检测线棒出现绝缘与导体脱壳缺陷；出槽口和端部线棒的窄面绝缘与槽部线棒的宽面绝缘相比，声衰减大而波速一致；现场试验验证了波速不受绝缘结构和现场测试条件的影响，而声衰减受以上因素影响很大(参见 Hao et al，中国电机工程学报， Vol.23 No.4)； V min 随运行年数明显减小， V av 随运行年数慢慢越小。

The RAPD results illustrate that the phylogenetic relationship betweenBothriocephalid tapeworm parasitic in Grass carpCtenopharyngodon idellus(C.et V.and Common carp(Cyprinus carpio L.)from different regions ofChina is infraspecific with noticeable variance bwtween them.Thephylogenetic trees based on the 3 sequences analyses above are constructed,which show the following relationships:Bothriocephalid tapeworms fromGrass carp,Common carp and Luciobrama are found to be monophyletic,and are very close to Bothriocephalus opsariichthydis,but are divergent toanother monophyletic group comprising Bothriocephalid tapeworms fromZacco,Hemiculter and Leuciscus.On the basis of phylogenetic reconstruction,autapomorphic species conceptis used in species delimitation suitablefor determining four species in the present study:B.acheilognathi,B.opsariichthydis,and two other bothriocephalids parasitic respectively inHemiculter and Leuciscus.It is also deduced that the differentiation time ofBothriocephalid tapeworms parasitic in cyprinids is earlier than that of theirhosts,and the most recent specification happened about one million yearsago.Key words Bothriocephalid tapeworm Molecular Systematics

具体成果有：通过RAPD分析探明了我国不同地理分布的草、鲤鱼头槽绦虫的亲缘关系属于种下水平，并存在较高变异；通过基因合并分析重建头槽绦虫的系统发育关系，表明草鱼、鲤鱼及鯮鱼头槽绦虫是单系群，它们与马口鱼头槽绦虫亲缘关系较近，而与〓条、宽鳍鱲及雅罗鱼头槽绦虫构成的另一单系群亲缘关系较远；在此基础上，提出符合头槽绦虫种的界定的独征物种概念，据此确定鲤科鱼类寄生头槽绦虫的四个种：鱊头槽绦虫，马口鱼头槽绦虫，以及另两种分别寄生于〓条和雅罗鱼的头槽绦虫：根据上述研究推断鲤科鱼类寄生头槽绦虫的分化年代早于其宿主，最近的一次物种形成距今约一百万年左右。
