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。
Comparing with the digital circuit, analog circuit signal has a wide dynamic range and varied waveform changes, Therefore, they fault detection has been the focus studied.
相对于数字电路，模拟电路的信号动态范围宽、波形变化大，因此对其的故障检测一直是研究的重点。
