| 9 | Behavior of High Performance PVA Fiber Reinforced Cement Composites in Triaxial Compression显示文摘Based on an extensive experimental program,the paper studies the behavior of HPFRCC under triaxial compression. The experimental parameters are lateral confining pressure and PVA fiber content by volume. The test results indicate that ultimate strength and peak strain are significantly improved with the increases of confining pressure. The confining effect introduced by the fibers becomes minor in triaxial compression tests,where there is relatively high external confining pressure. The axial stress-strain curves with different confining pressure and different PVA fiber content by volume are obtained. Lateral confining pressure constraints the lateral expansion of HPFRCC,so there is a big plastic deformation with its ultimate strength improved. At lower confining pressure,PVA fiber content by volume has some effect on the decreased section of stress-strain curve. According to test results,the paper establishes formula of confining pressure with ultimate strength and axial peak strain respectively. | LI Y LIANG X W LIU Z J | 2010 | 武汉理工大学学报2010,32,17: | 10 |

| 11 | Would integrated Western and traditional Chinese medicine have more benefits for stroke rehabilitation? A systematic review and meta-analysis显示文摘Background Stroke is a major cause of death or long-term disability worldwide.Many patients with stroke receive integrative therapy consisting of Western medicine(WM)and routine rehabilitation in conjunction with Chinese medicine(CM),such as acupuncture and Chinese herbal medicine.However,there is no available evidence on the effectiveness of the combined use of WM and CM interventions in stroke rehabilitation.Aims The purpose of this meta-analysis is to evaluate the results of all individual studies to assess the combined use of CM and WM in stroke rehabilitation compared with WM only.Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed.MEDLINE,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI)were searched.The included outcomes were dependency,motor function,depression and swallowing function.Subgroup analysis was performed,and publication bias was assessed using funnel plots.Summary of review 58 studies and 6339 patients were included in the meta-analysis.Subgroup analysis revealed that combined therapy comprising both acupuncture and WM had a superior effect on improving dependency and swallowing function compared with standard WM therapy alone.Potential superiority of combined therapy comprising CM and WM in improving depression compared with standard WM therapy was also found.Conclusions Our results indicate that the combined use of CM and WM could be more efficacious in stroke rehabilitation compared with the use of WM therapy alone.However,most studies were short in duration(2 to 4 weeks)and prone to different types of biases,which prevents making any conclusion regarding the long-term effects and raises concerns regarding true efficacy in context of high likelihood of Hawthorn bias.So,more randomised controlled trials with more rigorous design and longer duration of treatment and follow-up need to be conducted to compare WM alone versus WM and CM combined. | Linda LD Zhong Ya Zheng Alexander Y Lau Norman Wong Liang Yao Xingyao Wu Tengteng Shao Zhenxing Lu Huijuan Li Chun Sum Yuen Jianwen Guo Suzanne Lo Janita Chau Kam Wa Chan Bacon Fung Leung Ng Zhaoxiang Bian Edwin Chau-leung Yu | 2022 | Stroke & Vascular Neurology2022,7,1: | 7 |
| 12 | Modified Cam-Clay model incorporating unified nonlinear strength criterion显示文摘A unified nonlinear strength criterion(i.e UNS criterion) is proposed,for the sake of versatility,to capture the complex strength behaviors of frictional materials in geotechnical field.It covers wide ranges on the meridian and octahedral planes to describe nonlinear strength behaviors of soils.The Modified Cam-Clay model,incorporating the unified nonlinear strength criterion,is employed as an example to derive working mathematical equations and to illustrate yielding surfaces in three-dimensional stress space for improving the model's predictive capability.The unified nonlinear strength criterion,demonstrated here,is capable of capturing the experimental results of different types of soils on the meridian and octahedral planes.In addition,the revised model,based on this unified nonlinear strength criterion,though very simple,is versatile to predict the true triaxial test results from literature when considering the influences of the intermediate principal stress on strength and deformation under complex stress conditions. | XIAO Yang LIU HanLong LIANG Robert Y | 2011 | Science China(Technological Sciences)2011,54,4: | 6 |
| 13 | 考虑时变性热强度和时变性热量分配比的铣刀前刀面瞬态温度场建模研究显示文摘高速周铣是一种加工范围广和生产效率高的机械加工方式,其加工过程中会出现大量铣削热,尤其是加工导热率较低的工件时更为显著,铣削温度上升和下降的周期性变化会加速刀具磨损,进而降低工件表面加工质量。由于目前在周铣加工研究中缺乏对铣刀前刀面瞬态温度场的研究,为此,综合考虑第二变形区时变性热强度、时变性热量分配比以及前角因素,提出了一种基于'移动热源法'的铣刀前刀面瞬态温度场建模方法。首先建立第一变形区热源影响下的铣刀前刀面瞬态温度场温升模型,其次建立第二变形区热源影响下的铣刀前刀面瞬态温度场温升模型,最后进行温升模型叠加计算,进而建立铣刀前刀面瞬态温度场模型。仿真与试验结果验证了模型的准确性,该模型将进一步为研究铣刀前刀面抗磨设计提供理论支持。 | 岳彩旭 都建标 刘献礼 LIANG S Y WANG Lihui 高海宁 李恒帅 | 2019 | 机械工程学报2019,55,9: | 6 |

| 15 | 基于增广Huber正则化稀疏低秩矩阵的旋转机械微弱故障诊断显示文摘在多重故障相互耦合和强烈背景噪声下,提取大型旋转机械中的复合微弱故障特征是一个难点,针对这一问题,提出一种新的基于增广Huber正则化稀疏低秩矩阵(augmented Huber regularized sparse low-rank-matrix,AHR-SLM)的旋转机械故障特征提取方法,以大型减速机齿轮箱复合微弱诊断为例。该方法借助于非凸罚正则化稀疏低秩矩阵的思想,通过引入增广Huber罚函数代替传统最小化L1-norm融合套索算法,建立正则化目标成本函数,推导所建立模型的严格凸性,同时讨论模型严格凸性前提下的模型参数最优取值问题,并利用前向–后向算法对所建立模型进行求解。仿真算例与大型减速机齿轮箱微弱故障诊断实例表明:该方法不仅能提取隐藏在强烈外界噪声中的复合微弱故障特征,而且改善传统最小化L1-norm融合套索算法在提取微弱故障冲击时产生的稀疏系数低估与故障频率丢失问题,以及变分模态分解与快速谱峭度图特征提取算法产生的能量衰减与故障频率丢失问题。 | 李庆 胡炜 彭二飞 LIANG Steven Y | 2019 | 中国电机工程学报2019,39,15: | 5 |

| 17 | 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 |
