IRZ

Result: ① Whole heart weight ( WHW), WHW/ body weight, thickness of IRZ ventricular wall and the maximum perimeter of left ventricular chamber in OMI group were all obviously increased compared with those in Sham group, P < 0.05;

结果：①和Sham组相比，OMI组的全心重、左室重、全心重/体重比值、左心室腔最大内径均显著增加（均P<0.05）；

It was found that welding could reduce the corrosion fatigue properties of CF-60 steel because the fatigue properties of the Imcomplete Recrystal Zone ( IRZ) in HAZ were worse than those of matrix and the other zones.

其原因在于，焊接热影响区中的不完全重结晶区的腐蚀疲劳性能低于母材和其它组织区的疲劳性能。
