为了确定外流的重要性，中国科学技术大学天体物理中心开展了宽吸收线类星体的一系列研究，取得了一些进展：(1)宽吸收线区的紫外吸收物质的柱密度比原来预计高出2个量级，低电离吸收线形成于饱和的高电离吸收线区；(2)射电宁静的宽吸收类星体吸收物质主要在赤道面，并且不同的源吸收物质分布情况很不相同，而在射电强的类星体中，赤道和极向外流都是可能的；(3)共振散射线偏振表明，外流物质携带角动量。

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。

As the spectral width (Full width half maximum: FWHM) range from 6nm to 60nm, the simulation results show that the effect of the variation of the FWHM upon the output is small. When only the Verdet constant is considered, the output increased slowly with the increase of the FWHM. The simulation results are verified by the experiment.

当光源光谱宽度在6nm到60nm之间变化时，不同谱线宽度光源对系统输出影响的仿真结果表明：光源谱宽变化对系统输出的影响相对于其单色模型来说，相对变化小于10~(-3)，因此光源谱宽变化对系统输出的影响较小；如果完全消除了线性双折射和反射相移，则系统输出随光源谱宽的增加有微弱的增加：由于Verdet常量的影响最大，所以系统输出随光源谱宽的增加有微弱的增加；实验结果验证了该结论。

A number of v=0~57 vibration levels were determined and assigned. The levels cover more than 99% of the potential well depth of the state. No evident autoionization was found related to the levels belonging to the 13 g- state above the ionization threshold, implying the distinct character of the doubly excited valence state from the Rydberg states.

并发现13 g-态能级即使超过电离限时亦无明显的自电离倾向，反映了双电子激发态不同于里德堡态的独特性质。13 g-态是碱金属双原子分子电离限以下唯一的3 g-对称性的态和电离限下唯一较纯的双电子激发态，这些结果为分子结构和量子化学的定量研究提供了重要的信息；（2）通过检测Na 3d 3p原子荧光，观察到Na2分子的33 g和43 g+态在3s+3d解离限以上的预解离能级及其转动线宽加宽等。
