For transmission lines with no shunt reactor, the magnitude and the angle of the recovery voltage of fault phase under permanent faults are quite different from that under transient faults. 仿真实验验证该判据能可靠区分瞬时性故障和永久性故障,并且有较高的灵敏度。
No shunt signal through VS showed on CDFI. CDFI没有显示过室间隔分流束血流信号。
Urgent problems that society can no longer shunt aside. 社会再也无法回避的紧急问题。
The radiography right after implantation showed that there was slight remaining shunt in 18 cases ( 32.1 % ) and no remaining shunt in 38 cases ( 67.9 % ). 术后即刻经胸超声及造影显示38例(67.9%)无残余分流,18例(32.1%)存在微~少量残余分流。
Results Cases with Ivalon plug and Amplatzer device were all successful, no residual shunt or recanalization were found in the follow up. 结果用海绵塞子及Amplatzer堵闭器堵闭均成功,未发生残余分流和再通病例;
