1Oxygen and Nitrogen Effects on MC Carbide in K465 Nickel-Base Superalloy显示文摘Effects of oxygen and nitrogen on MC carbide in nickel-base superalloy K465 were investigated, because neither of the two gas elements was found to decide MC carbide morphology monotonically. The morphology of MC carbide under alloy solidified in conventional investment casting condition was observed to transform from script-type to block-type with the total oxygen and nitrogen content (gas content) in samples rising up from 1.2×10-6 mol/g to 2.6×10-6 mol/g. The area fraction and composition of the MC carbide also varied with increase of gas content. However, the morphology of MC carbide kept to be script-type even when gas content was up to 3.4×10-6 mol/g in samples solidified with a much higher cooling rate. These results indicate that effects of gas content on formation of MC carbide can be observed in specimens solidified with low cooling rate, but such changes in MC carbide cannot be found when the cooling rate is high.Wang L N Zheng Q Sun X F Guan H R Hu Z Q 2009稀有金属材料与工程2009,38,A03:4
2基于工作地点的分组干预对高血压控制的影响:一项随机临床研究显示文摘基于工作地点的干预可能为一种管理高血压的有效方法。但是目前缺少针对中国工作人群高血压控制情况的研究。本研究旨在评估基于工作地点的多组分别干预策略对改善血压控制的影响。研究设计及受试者:研究者在2013年1月至2014年12月于中国20个城区的60个工作地点进行了一系列高血压管理的随机临床试验。工作地点随机分为干预组(n=40)和对照组(n=20)。每个工作地点的受试者都需要完成一项横断面调查。袁源(摘译) 叶鹏(审校) Wang Z Wang X Shen Y Li S Chen Z Zheng C Kang Y Jiang L Hao G Chang C Gao R 2020中华高血压杂志2020,28,6:3
3中国成年女性初潮年龄与高血压风险的关系:大型国家代表性群体研究结果显示文摘本研究纳入中国高血压调查中年龄≥18岁的女性234867例,旨在探索中国成年女性初潮年龄与高血压风险的相关性。参与者被要求完成标准问卷,血压测量和体格检查由经过培训的医务人员完成。采用Spearman相关性分析探索初潮年龄和其他个体特征的相关性。采用logistic回归根据初潮年龄计算高血压发生的OR。结果显示,中国女性平均初潮年龄为14.8岁。袁源(摘译) 郑武洪(审校) Chen L Zhang L Chen Z Wang X Zheng C Kang Y Zhou H Wang Z Gao R 2021中华高血压杂志2021,29,10:3
