The corrosion and oxygen evolution behaviors of cast and rolled Pb–Ag–Nd anodes were investigated by metalloscopy, environmental scanning electron microscopy, X-ray diffraction analysis, and various electrochemical measurements. The rolled anode exhibits fewer interdendritic boundaries and a dispersed distribution of Pb–Ag eutectic mixtures and Nd-rich phases in its cross-section. This feature inhibits rapid interdendritic corrosion into the metallic substrate along the interdendritic boundary network. In addition, the anodic layer formed on the rolled anode is more stable toward the electrolyte than that formed on the cast anode, reducing the corrosion of the metallic substrate during current interruption. Hence, the rolled anode has a higher corrosion resistance than the cast anode. However, the rolled anode exhibits a slightly higher anodic potential than the cast anode after 72 h of galvanostatic polarization, consistent with the larger charge transfer resistance. This larger charge transfer resistance may result from the oxygen-evolution reactive sites being blocked by the adsorption of more intermediates and oxygen species at the anodic layer/electrolyte interfaces of the rolled anode than at the interfaces of cast anode.

目的：确定建筑容积率、建筑密度和建筑层数之间的关系,并将其作为主要的规划指标,研究其对室外风环境的影响。创新点：在以高层、高密度为特点的城市建设中,一个地块的用地规划指标可直接影响居住区的室外物理环境质量。一个高层建筑群的规划设计不应该只关注建筑物,还应考虑室外物理环境的品质。本研究从室外风环境角度出发,对13种＂容积率-建筑密度-建筑层数＂指标组合形成的高层建筑群布局进行对比,从而得到可直接服务于城市建设项目的规划策略。方法：1.通过确定建筑容积率、建筑密度和建筑层数之间的关系,建立三维高层建筑群布局模型,列出19种可能的指标组合（图2）;2.通过日照模拟分析工具Tarch和建筑消防间距计算筛选出13种符合当前规划要求的指标组合;3.运用风环境模拟软件Phoenics,对13种指标组合形成的高层建筑群布局进行风环境模拟运算;利用图形分析软件Photoshop CS,计算出舒适风面积比值,并进行相互对比（图3和4）;4.根据土建造价对不同建筑群布局的总造价进行对比（图6）。结论：在规划设计中,通常认为较低的容积率和较低的建筑高度意味着建筑体量较小,室外物理环境会更好。但是,本研究发现建筑层数越多、建筑高度越高,行人高度的室外舒适风区面积越大。不过,建筑层数从25层升到30层,舒适风区面积增加有限。加之考虑层数越高导致造价越高的因素,当面对容积率为2.0~4.0的高层地块时,不能简单地认为建筑层数最高的规划方案就是最好的方案。

Mutations in the haemochromatosis gene （HFE） influence iron status in the general population of Northern Europe, and excess iron is associated with the impairment of spermatogenesis. The aim of this study is to investigate the association between three mutations （C282Y, H63D and S65C） in the HFEgene with idiopathic male infertility in the Chinese Han population. Two groups of Chinese men were recruited： 444 infertile men （including 169 with idiopathic azoospermia） and 423 controls with proven fertility. The HFEgene was detected using polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP） technique. The experimental results demonstrated that no C282Y or $65C mutations were detected. Idiopathic male infertility was not significantly associated with heterozygous H63D mutation （odds ratio=O.801, 95% confidence interval=0.452-1.421, X2=0.577, P=0.448）. The H63D mutation frequency did not correlate significantly with the serum luteinizing hormone （LH）, follicle-stimulating hormone （FSH） and testosterone （T） levels in infertile men （P=0.896, P=0.404 and P=O.05, respectively）. Our data suggest that the HFEH63D mutation is not associated with idiopathic male reproductive dysfunction.
