Results There was significant correlation between hepatic vein Doppler waveform changes and fibrosis pathological stages.
结果慢性肝病肝静脉多普勒波形改变与肝纤维化病理分期之间具有一定相关性。
Objective: to analyse the correlation of hepatic vein diameter and Doppler waveform changes with liver histologic fibrosis in chronic liver hepatitis patients.
目的：探讨慢性病毒性肝炎肝静脉管径及多普勒频谱改变与肝组织病理纤维化程度的关系。
Near the critical point of the RLC-circuit, the residual voltage waveform changes form non-oscillating attenuation mode to distinct across zero oscillating mode when the peak current increases.
在RLC回路临界点附近，随着冲击电流峰值的增大，残压波波尾从非振荡衰减过渡到大幅度的过零振荡；
