为了解青岛市雾日PM_(1)中金属元素的污染程度及其来源,并评估其对人类健康的危害,依据能见度及湿度数据对雾日进行划分,结合正定矩阵因子分解法(PMF)源解析模型和健康风险评价模型研究青岛市雾日亚微米颗粒物(PM_(1))中金属元素的来源和健康风险.结果表明,清洁雾日PM_(1)浓度略高于清洁日,而污染雾日PM_(1)浓度是霾日PM_(1)的1.11倍,清洁日的3.07倍.秋冬季雾日金属元素受人为源影响,K元素含量最高;夏季雾日的主要贡献元素是典型的地壳元素Ca、Fe、Al及海盐Na元素.PMF结果表明秋冬季雾日PM_(1)中金属元素主要来自煤/生物质燃烧、机动车源、地壳源、海盐源、船舶源和工业源;夏季雾日PM_(1)中金属元素主要来自煤/生物质燃烧、机动车源、地壳源、海盐源、船舶源和工业源.夏季采样点位临海,海雾频发,海盐源为夏季雾日金属元素的重要贡献.健康风险评估结果表明,成年人与儿童暴露于青岛秋冬季雾日PM_(1)的非致癌风险均低于阈值.成人和儿童呼吸途径Mn的非致癌风险最高,儿童手口摄食As的非致癌风险(HQAS=0.50)最高.As(3.1×10^(-6))和Cr(1.9×10^(-6))的致癌风险均已超过致癌风险阈值,建议加强含Mn、As、Cr排放源的管控.

The SnCl2 reduction of 2-nitrocyclododecanone or 2-bromo-12-nitrocyclododecanone gave a colorless compound 2,3,5,6-bis（ortho-1,10-decylidene）dihydropyrazine 1a characterized by IR, NMR and X-ray diffraction analysis. Crystal data for 1a： Mr = 358.60, monoclinic, space group P2 1/n, α = 0.48028（3）, b = 2.8646（4）, c = 0.77097（6） nm, β = 98.432（12）°, V = 1.04924（19） nm^3, Dc = 1.135 g/cm^3, Z = 2, F（000） = 400 and μ（MoKa） = 0.065 mm^-1. All ^1H- and ^13C-NMR resonance lines of 1a were assigned by DEPT, COSY, HMQC and HMBC technology. In the crystal, the dihydropyrazine ring has a planar structure, two twelve-membered tings adopt [lene2333] conformation, their double bonds have cis-configuration, and the whole molecule has a center of symmetry. In solution, the symmetric ^1H- and ^13C-NMR signals suggest that two twelve-membered rings of 1a may adopt enantiomorphous [ lene2333] conformation existing in a dynamic equilibrium.

Ni-25Al-15Cr （atomic percent, %） alloy was directionally solidified （DS） under argon atmosphere in an Al2O3-SiO2 ceramic mold by standard Bridgman method. The microstructure of the as-fabricated alloy was studied using optical microscope, X-ray diffractometer, and scanning electron microscope. The alloy consisting of dendritic β- NiAl phase, interdendritic γ/γ′ phase, and transient layer γ′ phase, has been investigated. This alloy exhibits superplastic deformation behavior at 1 273-1 373 K over an initial strain rate range of 8. 35×10 ^-4 -1. 67×10^-2s^-1. The maximum elongation of 280% with strain rate sensitivity index m= 0. 22 was obtained at the temperature of 1 323 K and an initial strain rate of 8. 35×10^-3s^-1. Transmission electron microscopy （TEM） observations indicate that the superplastic deformation stems from the balance between high resistance （by dislocation sliding） and strain softening （by dynamic recovery and recrystallization）.

经过表面处理的短切玻璃纤维(GF)能够显著提升环氧树脂(EP)的强度、抗冲击性以及耐久性,GF改性EP材料均一性优于连续纤维增强EP,在工程领域有着重要应用。文章采用醇洗、偶联剂处理、酸刻蚀等改性方法处理短切GF,制备EP复合材料,研究短切GF的表面处理方式及添加量对EP/改性短切GF复合材料的流变行为和力学性能的影响。此外合成出一种含磷、氮、溴三种阻燃元素的反应型阻燃剂,在EP/改性短切GF体系中进行阻燃应用研究。结果表明:酸刻蚀处理的短切GF表面微观形貌较为粗糙,能够大幅增加体系的初始剪切黏度,固化后复合材料的力学性能也明显优于加入醇处理和偶联剂处理的GF的复合材料,酸刻蚀处理的短切GF含量为2.0%,复合材料的拉伸强度最高,为59.75 MPa。合成的反应型阻燃剂阻燃效果显著,阻燃剂含量为10%时,复合材料的峰值热释放速率及总热释放量均较纯EP明显降低,且力学性能同时得到提升。

Let G be a nonempty closed subset of a Banach space *** B(X)be the family of nonempty bounded closed subsets of X endowed with the Hausdorff distance and B_(G)(X)={A∈B(X):A∩G=φ},where the closure is taken in the metric space(B(X),H).For x∈X and F∈B_(G)(X),we denote the nearest point problem inf{||x-g||:g∈G}by min(x,G)and the mutually nearest point problem inf{||f-g||:f∈ F,g∈G}by min(F,G).In this paper,parallel to well-posedness of the problems min(a:,G)and mm(F,G)which are defined by De Blasi et al.,we further introduce the weak well-posedness of the problems min(x,G)and min(F,G).Under the assumption that the Banach space X has some geometric properties,we prove a series of results on weak well-posedness of min(x,G)and min(F,G).We also give two sufficient conditions such that two classes of subsets of X are almost Chebyshev sets.

MoSi2 samples were prepared by a self-propagating high-temperature synthesis (SHS) and a hot-press technique. The sliding friction and wear properties of intermetallic MoSi2 against AISI10045 steel under dry friction and oil lubrication conditions were investigated with a MRH-5A type ring-on-block friction and wear tester. The elemental composition, microstructure and worn surface morphology of the MoSi2 material were observed and analyzed by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The synthetic parameter pv value reflecting friction work, was used to discuss the tribological properties of MoSi2 material. The results show that 1) oil lubrication can obviously improve the tribological properties of MoSi2, 2) the bigger the pv value, the greater the antifriction and the abrasive resistance of MoSi2 under oil lubrication, 3) with an increase in the pv value, the wear mechanism of MoSi2 material under dry sliding friction is the fatigue fracture and adhesive wear and 4) under oil lubrication the wear mechanism is mainly fatigue pitting.

为了解决中文命名实体边界识别产生歧义和识别不准确的问题,提出了基于深度学习的中文命名实体边界识别算法。对以“字”和“词”的中文实体边界识别方法存在的缺陷进行分析,根据句子中命名实体的位置编码原理,对每个命名实体的首尾位置添加标签,以划分每个实体的边界,同时用标签表示命名实体之间的关系,提出了基于位置标注的中文命名实体识别的词汇信息融合方法,并引入注意力机制对词汇信息融合模块进行改进。利用深度学习的优势,将深度学习与词汇信息融合相结合,构建基于深度学习的中文命名实体词汇信息融合模型和基于深度学习的中文命名实体边界识别算法。该算法在Resume等数据集上进行对比实验和消融实验,查准率为95.94%,查全率为96.46%,F1值为96.58%。实验结果表明,该算法与Lattice等算法相比,准确率、查准率、F1值分别提高了1.13%、2.35%、2.12%。该算法在解决目前中文命名实体识别存在的边界识别不准确和存在歧义的问题上更优。
