基于中英文可比较语料的中文零指代消解

针对中文篇章中的零指代问题,提出一种基于中英文可比较语料进行中文零指代识别和消解的方法,并提出英文对等句的概念。利用对等句,重新定义句子间隔,并引入双语词对齐特征。在基准平台基础上,从零指代项识别和零指代项消解两个方面进行研究。在Onto Notes5.0语料上的实验结果表明,与目前性能最好的系统相比,新提出的基于中英对等语料的中文零指代方法取得更好的性能。

Mechanical behavior of a near α titanium alloy under dynamic compression: Characterization and modeling

Dynamic compression tests under strain rates from 870 s^?1 to 2100 s^?1 were conducted for a near α Ti–8Al–1Mo–1V titanium alloy with equiaxed microstructure. Compression behavior, adiabatic shearing and band microstructure were investigated via characterization and calculation. The results demonstrate that all dynamic constitutive curves exhibited obvious stress fluctuation phenomenon with double increase-decrease changing stages at the primary stage of compression. The dislocation multiplication theory can be used to explain this phenomenon. After the stress fluctuation period, work hardening coexisted with the thermal softening, resulting in the slow hardening tendency in constitutive curves. J-C model was utilized to quantify the dynamic constitutive curves. The deviations between the predicted and experimental curves under high strain rates may be attributed to the over-consideration of thermal softening effect in J-C model. Adiabatic shearing band (ASB) began to form under the strain rate of 2100 s^?1. A total shearing strain of 8.1 within ASB achieved in 8.9 μs, corresponding to a local strain rate of about 9.1 × 10⁵ s^?1 and is over 430 times of the macro strain rate. Post annealing was conducted on ASB before EBSD characterization. Due to the static recrystallization during annealing, the α phase within ASB generally presented as ultra-fine grains less than 1 μm in diameter.     

糖尿病足部辅具研究进展

 糖尿病足是糖尿病患者最严重的并发症之一。设计合理的足部辅具可有效实现糖尿病患者足底高压区域卸载和足底压力分布优化，有助于降低足溃疡发生率和复发率、延缓足溃疡恶化和截肢周期。综述了糖尿病足部的评估方法、足部辅具的设计原则、制作技术以及临床应用效果，分析发现研究主要以糖尿病足部形状与破损情况为依据，通过结构设计、材料组合等实现降低足底压力峰值、保护足部的目的。然而，目前的糖尿病足部辅具仍需进一步结合足部生理参数监测、主动防护等功能，以更实时、准确地监测糖尿病足部健康水平，更智能、有效地维护足部健康。关键词糖尿病足；足部辅具；压力卸载；智能辅具     

泡桐木夹层梁的弯曲疲劳试验

对采用真空导入工艺的泡桐木夹层梁进行4点弯曲疲劳试验,研究发现泡桐木夹层梁的破坏形式主要有界面的脱黏、芯材的剪切破坏、面板分层等。试验过程中采集试件的S-N曲线,采用3种寿命预测公式对其进行线性拟合,得到该泡桐木夹层梁的寿命预测公式。基于S-N曲线在实际工程中的应用,引入失效率的概念,采用双参数的Weibull函数分布,对不同应力等级下的失效率进行研究,从而得到泡桐木夹层梁P-S-N曲线。     

Effects of Cr and Mo elements on the microstructures and compressive properties of the in situ (TiC_xN_y–TiB_2)/Ni cermets

In-situ(TiC_xN_y–TiB_2)/Ni cermets with 70 wt%TiC_xN_y–TiB_2 were successfully fabricated by combustion synthesis and hot pressing sintering in Ni-Ti-B_4C-BN powder systems.The microstructures,density,compressive properties,and hardness of the TiC_xN_y–TiB_2/Ni cermets with the addition of 0–8 wt%Cr/Mo to the Ni-Ti-B_4C-BN powder systems were compared and analysed.The results showed that the ceramic particles distributed uniformly in the cermets,and the size of the ceramic particles reduced with the Cr/Mo addition.Both Cr and Mo addition can improve the hardness,compressive properties,and fracture strains of the cermets.The hardness,compressive strength,and fracture strain of the(TiC_xN_y–TiB_2)/(Ni+Cr)cermets increased from 1561 HV,2.94 GPa,and 2.9%to 1864 HV,3.65 GPa,and 3.4%,respectively when the Cr content increased to 5 wt%.The hardness and compressive strength of the(TiC_xN_y–TiB_2)/(Ni+Mo)cermets increased from 1561 HV and 2.94 GPa to 1902 HV and 3.43 GPa,respectively when the Mo content increased to 8 wt%.The cermets with Cr had better compressive properties than the cermets with Mo.
