The origin of the modulated structure in Sr2CuO3+δ (δ = 0.4): [CuO2] in-plane oxygen vacancy or apical oxygen vacancy?

We propose the question of the modulated structures of copper oxide is caused by the [CuO₂] in-plane oxygen vacancy or apical oxygen vacancy. Sr₂CuO_3+δ single-crystal samples were prepared using high-temperature and high-pressure methods. The major phase of Sr₂CuO_3+δ (δ = 0.4) single-crystal system is found to be constituted by the 5 a modulated structure with the Fmmm space group, which originates from the [CuO₂] in-plane oxygen vacancy appearing in octahedral Cu-O. Besides, the presence of the [CuO₂] in-plane oxygen vacancy may obliterate the superconductivity of the system. Experimental results deduce that the oxygen vacancy may appear in the apical oxygen sites in high-temperature copper oxide superconductors.

基于DTW改进算法的孤立词识别系统的仿真与分析

传统的DTW算法在进行孤立词语音识别时着重于时间规整和语音测度的计算，而没有对数据的可靠性和有效性进行分析。本文提出了一种改进的端点检测算法，并采用一种改进的DTW算法，在计算机上进行了仿真。实验结果表明采用改进后的DTW算法有效的降低了识别时间和存储数据量，提高了系统性能。     

Encapsulation and Ostwald Ripening of Au and Au–Cl Complex Nanostructures in Silica Shells

We report a general template strategy for rational fabrication of a new class of nanostructured materials consisting of multicore shell particles. Our approach is demonstrated by encapsulating Au or Pt nanoparticles in silica shells. Other superstructures of these hollow shells, like dimers, trimers, and tetramers can also be formed by nanoparticle‐mediated self‐assembly. We have also used the as‐prepared multicore Au–silica hollow particles to perform the first studies of Ostwald ripening in confined microspace, in which chloride was found to be an efficient mediating ligand. After treatment with aqua regia, Au–Cl complex is formed inside the shell, and is found to be very active under in situ transmission electron microscopy observations while confined in a microcell. This aspect of the work is expected to motivate further in situ studies of confined crystal growth.     

焉耆盆地原油物理化学特征及油源对比研究

在焉耆盆地侏罗系三工河组和八道湾组均发现原油,目前关于侏罗系产层原油的油源问题存在不同的认识。对研究区原油的物理、化学性质进行系统的研究,认为侏罗系三工河组和八道湾组原油不仅在物理性质上有一定的差别,而且在地球化学组成及生物标记化合物上也有一定的差异,应具有不同的来源。侏罗系三工河组原油属于典型腐殖型干酪根成因,而侏罗系八道湾组原油除了具有腐殖型干酪根成因的某些特征外,还具有湖相泥岩生烃的特点。通过原油与各类源岩生物标志物进一步对比分析发现,侏罗系三工河组原油与西山窑、三工河组烃源岩及石炭系、三叠系烃源岩地球化学特征均存在明显差异,与侏罗系八道湾组烃源岩对比性较好。侏罗系八道湾组原油与八道湾组、三叠系源岩有一定相似性,因此认为八道湾组源岩为其主要源岩,三叠系源岩也有一定的贡献。目前勘探生产主要以八道湾组烃源岩为目标,下一步应加强对三叠系烃源岩贡献区带的勘探部署。
