The setting schemes of the resistance coefficient and the least tripdifferential current for the current differential protection based on sampled values using fault component are discussed.
Chronic lymphadenitis and lymph node hyperplasia clinical diagnosis and differential diagnosis is difficult, mainly to exclude the possibility of tuberculosis on the trip.
慢性淋巴结炎和淋巴结增生的诊断和鉴别诊断临床很困难,主要排除一下结核的可能就行了。
