随着一体化从经济领域"外溢"到社会领域,为了实现"社会欧洲"的建设目标,欧盟在重重压力之下构建了家庭友好政策体系。其出发点是提供劳动力保护,帮助父母协调家庭与工作的矛盾。但是由于其潜在目标是促进劳动力市场的公平竞争而非实现性别平等,因此欧盟家庭友好政策仍然存在着种种缺陷。本文以父母假指令为例,从政策文本、实施水平、欧洲法院的判例三方面对欧盟家庭友好政策进行性别视角分析,认为以上三方面存在的不利因素不仅严重制约了父母假指令效力的发挥,而且还对欧洲社会一体化进程造成较大的负面影响。

Fingerprint has been widely used in a variety of biometric identification systems in the past several years due to its uniqueness and immutability. With the rapid development of fingerprint identification techniques, many fingerprint identification systems are in urgent need to deal with large-scale fingerprint storage and high concurrent recognition queries, which bring huge challenges to the system. In this circumstance, we design and implement a distributed and load-balancing fingerprint identification system named Pegasus, which includes a distributed feature extraction subsystem and a distributed feature storage subsystem. The feature extraction procedure combines the Hadoop Image Processing Interface（HIPI） library to enhance its overall processing speed; the feature storage subsystem optimizes MongoD B＇s default load balance strategy to improve the efficiency and robustness of *** and simulations are carried out, and results show that Pegasus can reduce the time cost by 70% during the feature extraction procedure. Pegasus also balances the difference of access load among front-end mongos nodes to less than 5%. Additionally, Pegasus reduces over 40% of data migration among back-end data shards to obtain a more reasonable data distribution based on the operation load（insertion, deletion, update, and query） of each shard.

开展了钍样品装置内钍核参数的积分中子学基础研究.参考混合堆概念设计搭建了内部放置了钍样品的一维贫铀/聚乙烯交替系统装置,采用加速器D-T中子源模拟聚变堆芯,利用前期开发的离线伽马测量方法测定了不同位置、不同中子谱情况下的232Th(n,γ)反应率,不确定度约为5%.结果显示,聚乙烯对14.1 MeV中子的慢化作用可有效提升钍俘获率,且贫铀对钍俘获率也有显著提升作用.实验结果与主流核数据库计算结果的对比显示,ENDF/B-VI.6和JENDL-3.3数据库的计算值比实验值平均约大6%,而较新的ENDF/B-VII.0数据库的计算值比实验值平均约大4%.因此,相比于之前数据库的钍核数据,ENDF/B-VII.0的计算值与实验结果匹配得较好,可作为相关概念设计的推荐核数据库.

Two kinds of ultra-high strength cold rolled dual phase steels have been developed by designing C-Si-Mn-Cr and C-Si-Mn-Cr-Mo alloy systems. Tensile strength and elongation of both steels exceed 1100 MPa and 10%,respectively. The microstructures of both steels consist of massive martensite and ferrite. And the massive martensite of Mo-free steel disperses in the ferrite with volume fraction of 64%. However,the massive martensite of Mo-containing steel is connected or closed by small martensite islands each other,and martensite volume fraction is 69%. As to Mo-free steel,the yield strength,yield ratio,and work hardening exponent n are 548 MPa,0.49,and 0.26,respectively. As for Mo-containing one,the yield strength,yield ratio,and n value are 746 MPa,0.66,and 0.33,respectively. Besides,the ferrite of Mo-free steel is deformed at the initial stage of plastic deformation. However,for Mo-containing one,Mo solution strengthened ferrite and small overaged martensite islands are deformed preferentially at small strain,which causes the yield strength to reach approximately 200 MPa higher than that of Mo-free steel.

A series of blue phosphor hosts, using 3,6-1inked carbazole with δ-π tetraphenylsilane segment as the mainchain and modified by peripheral cyanohexyl group with different ratios, was designed and synthesized. These poly-mers show good solubility in common organic solvents. They all possess wide bandgap of 3.40 eV, high thermalstabilities and good film forming abilities. The peripheral cyanohexyl substituents have no effect on the polymerbackbones but enhance the electron transporting properties of the polymers in devices. Among them, doped devicesusing poly[（tetraphenylsilicon/9-hexy1-9H-3,6-carbazole）50-co-（tetraphenylsilicon/9-hexanenitrile-9H-3,6-carbazole）]50（PCNCzSi50） as the host and bis[（4,6-difluorophenyl）pyridinato-N, C2]-（picolinato）iridium（Ⅲ）（FIrpic） as the guestshow the best performance with the maximum current efficiency and power efficiency of 2.00 cd/A and 1.40 lm/W,respectively.

随着全球老龄化加剧,骨质疏松症等与年龄相关的骨骼代谢疾病发病率不断上升,寻求安全有效的治疗干预方法至关重要。目前肠道微生物及其代谢产物调节骨代谢已成为研究的热点。短链脂肪酸(short-chain fatty acids,SCFAs)如乙酸、丙酸和丁酸等,能够通过肠-骨轴发挥骨形成和骨吸收的调节作用,对骨稳态调节具有一定的积极作用,并能改善炎症性骨丢失。本文综述SCFAs通过内分泌、免疫、改善营养吸收等途径调控骨代谢稳态,以期为老年代谢性骨病的预防和治疗提供科学依据。
