This paper identifies the contributions of p-a-SiC：H layers and i-a-Si：H layers to the open circuit voltage of p-i-n type a-Si：H solar cells deposited at a low temperature of 125℃. We find that poor quality p-a-SiC：H films under regular conditions lead to a restriction of open circuit voltage although the band gap of the i-layer varies widely. A significant improvement in open circuit voltage has been obtained by using high quality p-~SiC：H films optimized at the ＂low-power regime＂ under low silane flow rates and high hydrogen dilution conditions.

低的强度极大限制了工业纯钛的应用。采用超声表面深滚压(Ultrasonic severe surface rolling,USSR)制备了高强度、耐腐蚀、光洁表面的高性能纯钛板材。单次USSR加工在纯钛表面获得了厚度约1.3 mm的梯度硬化层和良好镜面效果的光洁表面;USSR试样具有梯度纳米结构表面层,即晶粒尺寸、位错和孪晶密度随深度梯度变化,最表面层晶粒细化至52.2 nm;USSR试样屈服强度和抗拉强度相比未加工试样分别提高了33.8%和10.9%,表面硬度提高了50.9%,同时保持了20.8%的断裂延伸率;USSR试样在Hank’s溶液中的钝化电流密度降低,极化电阻增大,钝化膜稳定性和钝化能力提高。USSR试样的高强度主要来源于晶界强化、位错强化、孪晶强化和异质变形诱导强化;高密度非平衡晶界和光洁表面有利于稳定钝化膜的形成,提高了纯钛钝化能力。研究结果为工业纯钛力学性能和腐蚀阻力的改善提供了新的思路。

目的:通过meta分析评估同型半胱氨酸(homocysteine,Hcy)水平与代谢性心血管疾病发生及死亡风险的相关性。方法:计算机检索Pubmed、中国知网(CNKI)、万方数据库和维普数据库,检索时限为建库至2023年7月24日。经过文献筛选、资料提取和质量评价,采用RevMan 5.3软件进行meta分析。结果:共纳入16篇文献,其中7篇为队列研究,9篇为随机对照试验(randomized controlled trial,RCT)。队列研究meta分析结果显示,与Hcy水平正常者相比,Hcy水平较高者全因死亡率(RR=2.38,95%CI:1.71~3.32)、代谢性心血管疾病(RR=1.91,95%CI:1.46~2.49)、卒中(RR=2.26,95%CI:1.91~2.67)和冠心病(RR=2.32,95%CI:1.40~3.83)的发生/死亡风险增加;RCT研究meta分析结果显示,叶酸联合B族维生素干预可降低人体内Hcy水平(RR=-2.85,95%CI:-3.86~-1.83),但试验组和对照组全因死亡率、代谢性心血管疾病、心肌梗死和卒中的发生/死亡风险均无统计学意义(均P>0.05)。结论:队列研究结果显示,体内Hcy水平升高会增加代谢性心血管疾病的发生风险和全因死亡风险。RCT结果显示,叶酸联合B族维生素干预虽然能降低体内Hcy水平,但远期内并不能观测到对代谢性心血管疾病的影响。
