| 1 | Investigation into the Vibration of Metro Bogies Induced by Rail Corrugation显示文摘The current research of rail corrugation mainly focuses on the mechanisms of its formation and development. Compared with the root causes and development mechanisms, the wheel–rail impacts, the fatigue failure of vehicle-track parts, and the loss of ride comfort due to rail corrugation should also be taken into account. However, the influences of rail corrugation on vehicle and track vibration, and failure of vehicle and track structural parts are barely discussed in the literature. This paper presents an experimental and numerical investigation of the structural vibration of metro bogies caused by rail corrugation. Extensive experiments are conducted to investigate the effects of short-pitch rail corrugation on the vibration accelerations of metro bogies. A dynamic model of a metro vehicle coupled with a concrete track is established to study the influence of rail corrugation on the structural vibration of metro bogies. The field test results indicate that the short-pitch rail corrugation generates strong vibrations on the axle-boxes and the bogie frames, therefore, accelerates the fatigue failure of the bogie components. The numerical results show that short-pitch rail corrugation may largely reduce the fatigue life of the coil spring, and improving the damping value of the primary vertical dampers is likely to reduce the strong vibration induced by short-pitch rail corrugation. This research systematically studies the effect of rail corrugation on the vibration of metro bogies and proposes some remedies for mitigating strong vibrations of metro bogies and reducing the incidence of failure in primary coil springs, which would be helpful in developing new metro bogies and track maintenance procedures. | LING Liang LI Wei FOO Elbert WU Lei WEN Zefeng JIN Xuesong | 2017 | Chinese Journal of Mechanical Engineering2017，30，1： | 8 |

| 3 | Investigation on magnesium degradation under flow versus static conditions using a novel impedance-driven flow apparatus显示文摘This article reports a novel impedance-driven flow apparatus and its applicability for studying magnesium degradation under flow versus static conditions. Magnesium has potential to be an effective biomaterial for use inside the human body due to its biodegradability and biocompatibility.Magnesium undergoes degradation reactions in aqueous solutions such as body fluids, leading to mass loss and pH increase of the surrounding fluid. To compare the degradation process of magnesium under flow versus static conditions, a novel flow apparatus consisting of an impedance pump and a flow chamber was designed and constructed. In addition to low-cost, this apparatus is flexible to be sterilized and assembled, and is small enough for use inside an incubator, making it appealing for measuring and comparing magnesium degradation in vitro under flow versus static conditions. The average flow rate in this flow apparatus was 2.8 ml/s, mimicking the flow rate(2.6 ml/s) in coronary artery. In a simulated body fluid(SBF), magnesium samples lost their mass at a much faster rate under the flow condition than that under the static condition. Starting with a pH of 7.4, the SBF showed a pH increase to 8.5 under the flow condition within 96 h due to the degradation of magnesium, greater than the pH increase under the static condition.The results of this study demonstrated the effects of fluid flow on magnesium degradation using the impedance-driven flow apparatus, providing useful design guidelines for magnesium-based implants that may be exposed to body fluid flow. | Elbert David Mai Huinan Liu | 2014 | Progress in Natural Science:Materials International2014，24，5： | 4 |
| 4 | 老年复杂糖尿病患者的潜在过度治疗显示文摘价值对于存在多种严重合并症及功能受限的老年人来说,强化血糖控制所带来的伤害很可能超过其所带来的益处。目的通过健康状况检测老年糖尿病患者的血糖控制水平,并评估糖尿病潜在过度治疗的发生率。设计、设定及参与者对国家健康与营养调查研究中2001—2010年进行了糖化血红蛋白(HbA_(1c))测定的1 288例老年(≥65岁)糖尿病患者的资料进行横断面分析。所有分析具备复杂的调查设计以生成国家代表性评估。表现健康状况分类:非常复杂/差,至少有两项日常活动做起来困难,或者依赖透析;复杂/一般,至少有两项日常工具的使用困难,或存在至少3种慢性疾病;相对健康,不具备以上几点。主要结果及措施严格的血糖控制(HbA_(1c)<7.0%)以及糖尿病药物的使用很可能导致低血糖(胰岛素或磺酰脲类药物)。结果在1 288例老年糖尿病患者中,50.7%〔95%CI(46.6%,54.8%)〕的患者代表310万人〔95%CI(270,350)万人〕为相对健康状况,28.1%〔95%CI(24.8%,31.5%)〕的患者代表170万人〔95%CI(140,200)万人〕为复杂/一般的健康状况,21.2%〔95%CI(18.3%,24.4%)〕的患者代表130万人〔95%CI(110,150)万人〕为非常复杂/差的健康状况。总体来说,61.5%〔95%CI(57.5%,65.3%)〕的患者代表380万人〔95%CI(340,420)万人〕其HbA_(1c)<7.0%;这个比例在3种健康状况中无差别{62.8%〔95%CI(56.9%,68.3%)〕为相对健康状况,63.0%〔95%CI(57.0%,68.6%)〕为复杂/一般健康状况,56.4%〔95%CI(49.7%,62.9%)〕为非常复杂/差的健康状况(P=0.26)}。在HbA_(1c)<7.0%的老年患者中,54.9%〔95%CI(50.4%,59.3%)〕接受了胰岛素或磺酰脲类药物治疗;这个比例在各类健康状况糖尿病患者中近似。在研究涵盖的10年间,HbA_(1c)<7.0%的老年患者比例(P=0.34)、HbA_(1c)<7.0%且健康状况为复杂/一般或非常复杂/差的患者比例(P=0.27)、HbA_(1c)<7.0%健康状况为复杂/一般或非常复杂/差但接受胰岛素或磺酰脲类药物治疗的患者比例(P=0.65)均无明显变化。结论及意义尽管对于健康状况为复杂/一般或非常复杂/差的老年糖尿病患者来说,强化治疗所带来的伤害很可能超过其带来的益处,但是大多数患者2001—2010年已经达到了严格的血糖目标。大部分患者接受了胰岛素或磺酰脲类药物治疗,这可能导致严重的低血糖。本研究发现,有相当大比例的老年糖尿病患者接受了潜在过度治疗。 | elbert s.huang 本刊编辑部 | 2016 | 中国全科医学2016，19，15： | 2 |
