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。

I.! y P,{7 v: R; O0 D INTRODUCTIONIn most of the previous studies like [1-3], the effect of SRS in DWDM fiber opticsystems has been treated under various assumptions like undepleted pump approximation, wavelength independent fiber loss coefficient, triangular approximation of Raman gainprofile, negligible loss of energy whenever a short wavelength photon is transformed into a long wavelength photon (i.e., l i / l k ~ 1), equal power loading in all the wavelength channels and equal channel spacing.

ANP and CX43 began to express at 2nd week after induction and increased gradually,about 60% of the resulting myogenic cells were positive at 4th week after induction ,they were negative for uninduced cells.hMSCs'surface antigen profiles obtained by Flow Cytometry were negative for CD31\CD34\CD45 before and after induction,but CD90 expressed higher after induction while was weak positive before induction(P.05). Apotosis index was correlated with the cultural time after induction,The apoptosis rate of induced hMSCs was remarkably higher than control group(P.01),and the variation between groups was notable(P.05),the cell cycle analysis showed that the percentages of G_0/G_1phases were reduced significantly after induction. The expresstion levels ofβ-MHC and CTNT mRNA were undetectable before induction,began to increase at 1st、4th week after induction,reached the peak at 6th week and decreased after that,the expression of Bcl-2 and Bax mRNA varied regularly after treated with 5-azacytidine. hMSCs'resting membrane potential、range and rate of depolarization were heightened gradually after being induced.
结果:hMSCs诱导前为纺锤形,诱导后第2天部分细胞即开始发生形变,呈球形或短棒状,1周后胞浆中颗粒增多,约20~30%细胞边缘呈毛刷样变化;hMSCs表面抗原CD31、CD34、CD45在诱导前后差异无统计学意义,CD90未诱导时表达呈弱阳性,诱导后明显增高(P.05);ANP和CX43在诱导前无表达,诱导后第2周开始表达且表达随时间逐渐增强,但CX43在诱导后第5周表达量开始降低。hMSCs诱导后凋亡指数随诱导后培养时间增加,低浓度诱导组低于标准浓度诱导组,组间差异有统计学意义(P.05),G_0/G_1期细胞比例诱导后较对照组显著减少(P.05);β-MHC和CTNT基因分别在诱导后第1周和第4周时表达开始增强,在第6周时均达到高峰,第8周时表达开始衰减,Bcl-2、Bax基因表达呈时间依赖性变化,hMSCs经诱导后随心肌样细胞特征的表达膜静息电位、去极化幅值和去极化速率逐渐增高。
