在广深港客运专线莲花湖桥隧试验段应用光纤传感技术对钢轨横向位移、钢轨应变、桥梁上部结构与墩台相对位移等进行了监测。分析结果表明:列车经过时,钢轨轨腰与轨底处最大拉应变约为170×10^(-6),钢轨横向位移在1.0 mm以内,桥梁上部结构与墩台相对最大变形横向约为0.8 mm,纵向约为1.5 mm。分布式光纤传感器监测数据可以定性地反应温度作用下钢轨的应变状态,高铁基础设施现场安全监测宜采用光栅传感和分布式光纤传感相结合的方式。

以中国裁判文书网公布的司法文书为调查的数据来源,不再以特定腐败犯罪的"立案数""涉案人数"等作为参数标准,而是以"相对测量"为理论基础,以"潜伏期""数额""次数"3个核心参数来重新构建客观测量标准,可消解腐败实际状况与打击腐败努力之间的矛盾,也能够对中国不同时期、地区、行业的腐败状况进行更合理、全面的分析。运用新型客观测量标准,以"受贿、贪污、挪用公款"3类典型的腐败犯罪为分析依托,对沈阳、广州等6个副省级城市2013—2016年的司法数据进行统计,西安地区的廉洁状况最好、南京地区的腐败状况最严重;整体的数据显示中国近年来的社会廉洁状况有所提升。

对某双幅钢箱梁连续梁桥涡激振动进行风洞试验和数值模拟研究。基于二次开发UDF(user defined function)程序嵌入Fluent软件进行二维流固耦合分析,模拟了双幅桥梁断面的涡激振动;通过对比节段模型风洞试验及数值模拟结果,验证了数值模拟方法的可靠性,并从流场的角度直观分析双幅钢箱梁断面涡激振动机理。研究结果表明:上游幅主梁断面下表面的主涡与其背风侧的正压区的周期性变化诱发了上游幅主梁断面的竖向涡激振动;下游幅主梁断面上、下表面的旋涡交替作用于主梁断面并脱落,形成了周期性的作用,导致了下游幅主梁断面的竖向涡激共振;下游幅主梁断面上、下表面的旋涡分别在迎风侧栏杆与上游幅箱梁尾部、下游幅箱梁前端得到增强,导致了下游幅主梁断面的涡激振动的振幅大于上游幅主梁断面。研究结果为双幅桥梁或双钝体断面的涡激振动研究提供参考经验。

DearEditors,Multiple sclerosis(MS)is a chronic,autoimmune neurological disorder characterized by inflammatory demyelination of the central nervous system;it is associated with reduced mobility,cognitive impairment,and numerous comorbidities[1].Global MS incidence(2.1 per 100,000 person-years)and prevalence(30.1 per 100,000)have increased in recent years,and its prevalence is notably higher in Western countries,ranging from~30 to 200 cases per 100,000[2].In China,recent epidemiological research has shown that the crude prevalence was 2.44 per 100,000 in 2016[3],and the age-and sex-adjusted incidence was 0.235 per 100,000 person-years[4].Despite the relatively low prevalence compared with the global average,China has extensively addressed the well-being of over 30,000 MS patients,enrolling MS in China's First National List of Rare Diseases in 2018.
