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 change of average size of products along the radius at the exist of reactor has also been calculated. The calculated results indicate that the residence time is longer, the average size of products is larger, but the distribution of size is narrower, tending to self-preserving distribution; when the concentrations of reactants increase, the average size of products becomes larger, but the distribution of size becomes narrower; the gradients of reactants are greater, the average size is larger; the increasing of reacting temperature will cause the size of product to be larger under same residence time. The average size of product at the exist of reactor varies along the radius, has a maxim value.

模型计算结果表明，产物粒度随停留时间的增加而增大，但粒度分布变窄，趋向自保分布；产物粒度随反应物进料浓度的增加而增大，粒度分布随进料浓度的增大而减小；反应器中反应物浓度梯度较大（相当于化学反应为快反应）时，相同停留时间下所得到的产物平均粒度增加；反应温度的增加，粒子平均粒径增加，粒度分布变窄；反应器出口处粒子平均粒径，随着与对称轴的距离的增加，有一极大值，先增加，后减小。

Narrow Line Seyfert 1s (NLS1s, including high luminosity quasars with similar properties) are very important extrema of type Ⅰ AGNs. The unusualness of NLS1s is very useful to test the viabilities of AGNs models and thus provide a new way probing into AGN phenomena. The ratio of Fe to α-element (e. g., O, Ne, Mg...), Fe/α, can serve as an excellent indicator for constraining the ages of star-forming systems.

The communication technology used in GPS is a direct sequence spread spectrum structure. Using C/A Gold codes, it can cope with wideband noise (such as thermal noise and channel noise) or low power narrowband interference by its processing gain. But DS-SS can not reject high power narrowband interference completely. So we need an anti-jamming filter to reject the narrowband interference by using adaptive filters prior to dispreading.

它是利用直接展频的一种架构，因此，此系统能藉由C/A码的展频处理增益，来对付ㄧ些宽频的干扰或是低能量的窄频干扰，但是它无法应付高能量的窄频干扰，因此我们需要一个抗干扰滤波器在解展频之前来先将干扰去除。
