1CuZn37黄铜板料微塑性成形中的尺寸效应研究显示文摘为研究金属微塑性成形特点,对厚度不同及粗细两种晶粒尺寸的黄铜箔试样进行了单向拉伸和微弯曲实验,并采用经典塑性理论和应变梯度理论对弯曲回弹角进行了预测.粗晶粒板料试样单向拉伸实验表明,CuZn37黄铜的硬化曲线存在一种明显的尺寸效应,即板料厚度越小,屈服强度越高.弯曲回弹实验结果也存在另一种明显的尺寸效应现象,即板料厚度越小,回弹角越大.对这两种尺寸效应产生的原因进行了分析,指出应变梯度硬化对微成形工艺过程有重要影响.李河宗 董湘怀 王倩 申昱 DIEHL A HAGENAH H ENGEL U MERKLEIN M 2011材料科学与工艺2011,19,4:12
2全球药物滥用的疾病负担:来自2010年全球疾病负担研究显示文摘背景:直到目前还没有研究者系统地估计过全球及区域性的苯丙胺类、大麻、可卡因和阿片类药物依赖的患病率及其造成的疾病负担。我们旨在用伤残损失寿命年(YLDs)、过早死亡损失寿命年(YLLs)和伤残调整寿命年(DALYs)来估计药物依赖的患病率和其造成的疾病负担。方法:采用贝叶斯Meta回归的方法(Dis Mod-MR)对药物依赖的流行病学研究及2010年全球疾病、伤害及危险因素负担研究(GBD 2010)进行了系统综述,估计人群水平的药物依赖患病率。GBD 2010通过代表性社区调查和基于互联网的调查计算出新的失能权重。我们把估计的药物依赖患病率和新的失能权重结合起来估算药物依赖导致的YLDs、YLLs、DALYs和其作为相关疾病危险因素时导致的YLDs、YLLs和DALYs。结果:2010年,药物依赖直接造成了2千万的DALYs(95%UI(不确定区间)1.3-2.54千万),占全球全因DALYs的0.8%(0.6%-1.0%)。世界范围内,相比于其他药物,越来越多的人依赖于阿片类和苯丙胺类药物。阿片类药物依赖直接造成的疾病负担最大(DALYs为920万,95%UI为710-1140万)。在某些地区,药物依赖导致的DALYs所占比例比其他地区高出20倍,收入越高的国家药物依赖造成的负担所占比例也越高。注射吸毒所致HIV感染造成210万的DALYs(95%UI 110-360万),所致HCV感染导致50.2万的DALYs(95%UI 28.6-89.1万)。苯丙胺类药物依赖所致自杀造成85.4万的DALYs(95%UI 29.1-179.1万),阿片类药物依赖所致自杀造成67.1万的DALYs(95%UI 32.9-173.0万),可卡因依赖所致自杀造成32.4万的DALYs(95%UI 10.9-68.2万)。药物依赖导致的疾病负担最高的国家(>650 DALYs/10万人)包括美国,英国,俄罗斯和澳大利亚。结论:药物滥用是造成全球疾病负担的一个重要因素。为减少人群水平的疾病负担,我们需采取有效的措施(比如给予阿片类药物依赖者替代治疗及针具交换等)降低阿片类药物依赖和注射吸毒导致的疾病负担。王同瑜 Degenhardt L Whiteford HA Ferrari AJ Baxter AJ Charlson FJ Hall WD Freedman G Burstein R Johns Engell RE Flaxman A Murray CJ Vos T 2015中国药物依赖性杂志2015,24,6:3
