22 cases of acute right ventricular infarction ( ARVI). 22 cases of acute left ventricular infarction ( ALVI) and 9 cases of constrictive pericarditis were studied by ECG, hemodynamics and serum enzymes activities. 本文对22例急性右室梗塞(ARVI)、22例急性左室梗塞(ALVI)和9例缩窄性心包炎进行了心电图、血流动力学及血清酶学研究。
The solving method is find out by vibration testing and analyzing on ABB and ALVI blowers. The normal operating requirement for fan is realized. 通过对ABBALVI鼓风机的振动测试和分析,找出了解决的方法,使风机达到正常运行的要求。
