5Laser-induced oxidation assisted micro milling of high aspect ratio microgroove on WC-Co cemented carbide显示文摘Severe tool wear and poor surface quality are the main problems during micro machining of cemented carbide.In this work,an innovative hybrid process of laser-induced oxidation assisted micro milling(LOMM)was proposed to solve the problems.A nanosecond laser was utilized to induce oxidation of the WC-20%Co material,producing loose oxide which was easy to remove.The micro machinability of the material was improved by laser-induced oxidation.The oxidation mechanisms of cemented carbide were studied.A microgroove with a depth of 2.5 mm and aspect ratio of 5 was fabricated successfully.The milling force,surface quality and tool wear mechanisms were investigated.For comparison,a microgroove was also fabricated with conventional micro milling(COMM)using identical milling parameters.Results revealed that in LOMM the milling force and tool wear rate were extremely low during removing the oxide.The machined surface quality and dimensional accuracy achieved by LOMM were superior to those obtained by COMM.The surface roughness Saof the microgroove bottom reached 88 nm in LOMM,while the cross-sectional geometry of the microgroove was a trapezoid.Perpendicularity of the microgroove sidewall machined by LOMM was better than that by COMM.The tool wear forms in LOMM were coating spalling and slight tool nose breakage.Compared with COMM,the tool life in LOMM was prolonged significantly.It indicates that the proposed hybrid process is an effective and efficient way to fabricate high aspect ratio micro-features with high dimensional accuracy.Guolong ZHAO Hongjun XIA Yang ZHANG Liang LI Ning HE Hans Nφrgaard HANSEN 2021Chinese Journal of Aeronautics2021,34,4:3
6中国荷斯坦奶牛跛行和飞节损伤的风险因素分析显示文摘为了评估散栏牧场高产奶牛跛行率、飞节损伤与饲养管理、牧场设计之间的相关性,收集了中国34个大中型牧场高产牛群管理和卧床设计数据,如卧床设计、垫料类型和挤奶程序等。对每个圈的所有奶牛进行行走评分(1~5分)和飞节评分(1~3分)。其中行走评分大于等于3分定义为临床跛行,大于等于4分定义为严重跛行;飞节损伤大于等于2分为轻微损伤,3分为严重损伤。中国大中型牧场临床跛行率和严重跛行率分别为(31±12)%(分布于7%~51%)和(10±6)%(分布于0%~27%)。飞节轻微损伤率和严重损伤率分别为(40±20)%(分布于6%~95%)和(5±9)%(分布于0%~50%)。临床跛行率和严重跛行率与牧场的规模有显著相关性。随着牧场规模的增大,临床跛行和严重跛行有降低的趋势,每增加100头牛,临床跛行率降低(0.35±0.09)%,严重跛行率降低(0.15±0.06)%。牧场的新旧程度也显著影响跛行率,尤其是大于9年的牧场跛行率和严重跛行率明显升高。牧场的规模和新旧程度在引起临床跛行和严重跛行的因素中占49%和30%的作用。深槽卧床可降低轻微飞节损伤和严重飞节损伤的发生率(分别降低20.9%和3.65%)。大于9年的牧场飞节轻微损伤率和严重损伤率分别提高16.68%和7.17%。这2个变量可影响飞节轻微损伤和飞节严重损伤的52%和58%。总之,牧场之间的跛行率和飞节损伤率变异很大。良好的卧床设计和管理有助于降低跛行率和飞节损伤率。王艳明 Chapinal N Liang Y Weary D M Wang Y 2015中国乳业2015,0,7:3
7Stem cell differentiation and human liver disease显示文摘Human stem cells are scalable cell populations capable of cellular differentiation.This makes them a very attractive in vitro cellular resource and in theory provides unlimited amounts of primary cells.Such an approach has the potential to improve our understanding of human biology and treating disease.In the future it may be possible to deploy novel stem cell-based approaches to treat human liver diseases.In recent years,eff icient hepatic differentiation from human stem cells has been achieved by several research groups including our own.In this review we provide an overview of the f ield and discuss the future potential and limitations of stem cell technology.Wen-Li Zhou Claire N Medine Liang Zhu David C Hay 2012World Journal of Gastroenterology2012,18,17:3
