The results revealed that antigenic drift had occurred in virus strains of the same h9n2 subtype in the north of henan province during 1998 - 2002 . h9n2 subtype aivs were stable from 1998 to 1999 , since the mutual protection between 98a5 and 99s approached to 100 % , which was consistent with results in hi and vn tests
1998年和1999年h _ 9n _ 2亚型禽流感病毒较稳定， 98a5和99s毒株间的保护力接近100 ，在hi 、鸡胚中和、细胞中和试验结果的相关性均在0 . 74以上，表明两毒株间的抗原性相近。
The transient analysis and simulation studies in time - domain showed that the transient capacitance current of busbar is unable to be caught due to the limitation of the given sampling frequency , therefore the transient current singularity of the fault line and the non - fault line will approximate , which prevents to identify the fault line with the criterion calculation result of transient current protection
研究结果表明，线路出口故障时暂态电流保护完全失去选择性的根本原因是，在给定的采样频率的限制下，难以捕捉到过渡过程中极其短暂的母线分布电容中的暂态电流，从而故障线路与非故障线路暂态电流波形的奇异性相近，根据故障线路和非故障线路的暂态保护判据计算结果不能正确识别故障线路。
