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。

Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础,通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析,发现:励磁故障是一个大干扰稳定性问题,励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异,已远非正弦曲线,因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想;异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆,它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆,但不能保证完全失磁之外的其它状态不会进入该阻抗圆,因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。
