The microstructure and anti-corrosion behavior of Mg–Mn alloys by magnesium scrap have been investigated in this *** results show that the size of the Fe-rich particles in magnesium scrap decreases but the quantity increases with the Mn *** the presence of Mn-containing Fe-rich particles with unique symbiotic structure can eff ectively weaken the micro-galvanic corrosion,the presence of more free Fe(Fe-rich particles)does not necessarily lead to severe corrosion of the *** corrosion susceptibility of Mg–Mn–Fe alloy primarily depends on the solubility of iron in the Mg matrix,while it can be significantly reduced by suitable Mn ***,the tolerance limit of the Fe impurity can be expressed as Femax=0.0083 Mn(relative to the iron solubility).Only when the Fe/Mn ratio is below 0.0083 can the alloy have excellent corrosion resistance,with the corrosion rate changing in the scope of 0.38±0.09 to 0.54±0.15 mg/cm^(2) day and icorr from 3 to 9×10^(–4) A/cm^(2).

目的探讨游离皮瓣移植术中血液循环判断对皮瓣手术成功的指导意义。方法对2007年3月~2009年12月26例外伤后皮肤和软组织缺损的患者行游离背阔肌和股前外侧皮瓣移植,观察术中吻合血管后皮瓣的弹性、色泽,吻合处静脉血流的颜色和术后皮瓣的存活之间的关系。结果游离皮瓣移植术中吻合血管后,如皮瓣的弹性正常、色泽逐渐转为原供区切取前色泽,静脉血流颜色转为（淡）紫红色,则皮瓣术后存活良好。结论游离皮瓣移植术中静脉血流和皮瓣颜色等血液循环的判断对皮瓣存活有重要的参考的意义。
