1全髋关节置换术全身麻醉与蛛网膜下腔阻滞麻醉的比较显示文摘全髋关节置换术(total hip arthroplasty,THA)被认为是目前最成功的骨科手术之一,全世界每年约有一百万例THA手术。全身麻醉一直是髋关节手术的金标准,但目前THA手术也常采用蛛网膜下腔阻滞麻醉(脊椎麻醉),最佳的麻醉方法一直存有争议。既往的几项研究显示,相较于全身麻醉,椎管内麻醉具有减少失血量和输血需求量、降低血栓栓塞发生率和手术部位感染率的优点,但这些结果大都来自于小样本、单一机构,缺乏直接比较THA全麻与脊椎麻醉围术期效果的大样本、多中心研究。Basques BA Toy JO Bohl DD 胡玮 2015中国骨科临床与基础研究杂志2015,7,4:39
2侧流道泵叶轮轴径向间隙内流动特性数值模拟与验证显示文摘为了研究侧流道泵叶轮周围间隙质量流量交换规律,该文利用数值计算方法研究了侧流道泵在最高效率工况点下叶轮间隙处的流动规律,具体分析了其脉动扬程、交换质量流量、间隙处压力脉动情况、轴向速度变化等。结果表明,每旋转一个叶轮流道(18°),扬程出现一次完整的波动周期,每个周期内扬程最大值与最小值相差0.07 m左右;间隙外缘监测点的瞬时压力值明显大于其他4个监测点,顶部监测点压力值最大,在整个周期内的平均压力值大约是最小压力监测点的2.8倍;右侧间隙靠近外缘处的流体交换最激烈,该处速度绝对值最大;流体主要是在右侧间隙外缘大约0.8-1倍间隙半径处向侧流道流入,在0.53-0.8倍间隙半径处从侧流道流出至叶轮中;净交换流曲线近似呈三角函数图像变化,交替出现减小增大反复趋势,并且净交换流的波动导致侧流道泵扬程曲线的波动。该研究可为进一步提高侧流道泵的水力性能提供理论依据。张帆 Martin Bohle 裴吉 袁寿其 Annika Fleder 2015农业工程学报2015,31,10:10
3燃油温度和喷射压力对葵花籽油与柴油喷雾特性的影响显示文摘为探究纯植物油作为压燃内燃机替代燃料的雾化问题,利用纹影法对葵花籽纯植物油和普通柴油在不同试验条件下的喷雾特性进行了对比研究,分析了燃油温度和喷射压力对2种燃料喷雾贯穿距、喷雾锥角和空气卷吸作用的影响。研究结果表明:葵花籽油的喷雾贯穿距和喷雾锥角均随着喷射压力和燃油温度的升高而增大,与柴油的变化规律相似。温度从60℃升高到90℃,喷油压力为60 MPa时喷雾贯穿距和喷雾锥角的平均增幅分别为12.4%和9.6%,120 MPa时分别为5%和4.14%;喷油压力从60 MPa升高到120 MPa,温度为60℃时喷雾贯穿距和喷雾锥角的平均增幅分别为39.7%和16.7%,90℃时分别为30.6%和10.9%;当喷射压力、背景压力和燃油温度相同时,葵花籽油比柴油具有更大的贯穿距和更小的喷雾锥角,且喷雾贯穿距平均增幅为22.5%,喷雾锥角平均降幅为60.3%;升高燃油温度和升高喷射压力都会增强雾注的空气卷吸作用,但葵花籽油的空气卷吸作用要明显弱于普通柴油。研究结果可为纯植物油作为内燃机替代燃料的可行性研究提供参考。何旭 刘海 曾威霖 余红东 Bohl Thomas 田国弘 李向荣 刘福水 2014农业工程学报2014,30,15:8
4Relativistic-intensity near-single-cycle light waveforms at kHz repetition rate显示文摘The development of ultra-intense and ultra-short light sources is currently a subject of intense research driven by the discovery of novel phenomena in the realm of relativistic optics,such as the production of ultrafast energetic particle and radiation beams for applications.It has been a long-standing challenge to unite two hitherto distinct classes of light sources:those achieving relativistic intensity and those with pulse durations approaching a single light cycle.While the former class traditionally involves large-scale amplification chains,the latter class places high demand on the spatiotemporal control of the electromagnetic laser field.Here,we present a light source producing waveformcontrolled 1.5-cycle pulses with a 719 nm central wavelength that can be focused to relativistic intensity at a 1 kHz repetition rate based on nonlinear post-compression in a long hollow-core fiber.The unique capabilities of this source allow us to observe the first experimental indications of light waveform effects in laser wakefield acceleration of relativistic energy electrons.Marie Ouille Aline Vernier Frederik Bohle Maimouna Bocoum Aurelie Jullien Magali Lozano Jean-Philippe Rousseau Zhao Cheng Dominykas Gustas Andreas Blumenstein Peter Simon Stefan Haessler Jerome Faure Tamas Nagy Rodrigo Lopez-Martens 2020Light(Science & Applications)2020,9,1:3
