In last decades, topological materials [1-3] have attracted lots of research interest. Topological Kondo insulator （TKI） [4], as an exotic quantum state, has been proposed theoretically in two hexaborides StuB6 and YbB6, in which there is a d/f（p） band inversion at momentum point X [5]. There are lots of experimental work supporting the TKI state and metallic sur- face state in typical Kondo insulator SmB6 [6-10]. However, more and more experimental results demonstrated that YbB6 is trivial insulator at ambient pressure [11]. Under high pres- sure, the band gap of YbB6 will close and the dip band inver- sion can happen under pressure about 15 GPa [12].

The Mobei reservoir is a low-permeability-sandstone reservoir,due to differences in pore geometry,it can be divided into two independent reservoirs:A1 reservoir and A2 *** better understanding the water flooding development effects of Mobei reservoir,the mercury intrusion porosimetry,water flooding CT scanning and micro-CT scanning experiments are used in this *** result shows that the reservoir has the strong heterogeneity which is weaken gradually from A1 reservoir to A2 *** pore radius is mainly distributed in the 100e200 microns,the throat radius is mainly distributed in the 1e3 *** water flooding core experiment in each reservoir shows a short water-free oil production period and rapid water cut after *** A2 reservoir core flooding process is similar to piston displacement,the A1 reservoir core flooding process refers to the phenomenon(The fingering phenomenon in the process of core flooding in the A1 reservoir is obvious).The calculated water drive efficiency of the A2 reservoir is 61.2%,which is higher than 49.1%of the A1 *** to the CT scanning process,the Mobei oilfield has low micro displacement efficiency and the A1 reservoir has a smaller spread(sweep area)and higher residual oil saturation.

In situ electron microscopy, tomography, photoluminescence, and X-ray absorption spectroscopy were utilized to monitor and explain the formation and growth of internal pores within ZnO nanorods. Careful examination using electron microscopy and tomography indicate that nanosized intemal pores start appearing within the individual solution-grown ZnO nanorods upon exposure to 200 ℃. The pore volume growth rate is proportional to the heat treatment time, indicating that the process is diffusion controlled, akin to a reverse Ostwald ripening-like process. A manageable pore growth rate of 1.4-4.4 nm^3·min^-1 was observed at 540 ℃, suggesting that the effective control over internal porosity can be achieved by carefully controlling the heat-treatment profile. Mechanistic studies using X-ray absorption spectroscopy indicated that the pore formation is linked to the significant reduction of the number of zinc vacancies after heat treatment. An optimum condition exists where most of the native surface defects are removed, while the bulk defects are contained within the internal pores. It is also demonstrated that the internal porosity can be exploited to improve the visible light absorption of ZnO. A combination of the lower defect density and improved light absorption of the heat-treated ZnO films thus lead to an increase in the photo- electrochemical response of more than 20× compared to that of the as-grown ZnO.

为了解决溢洪道开挖量大、工程造价高、结构变形复杂、出口消能工对下游地基条件要求高等难题,小石口水库混凝土面板堆石坝采用了坝肩式溢洪道。与传统布置模式相比,坝肩式溢洪道具有枢纽结构布置紧凑,工程规模小、造价低等优点。与在堆石体上直接设置溢洪道相比,坝肩式溢洪道地基稳定可靠,可以避免复杂的结构变形问题,并允许通过较大的单宽流量。因此,在地形和岩石条件许可的情况下,坝肩式溢洪道布置型式值得推广。

This paper presents algorithmic components and corresponding software routines for extracting shoreline features from remote sensing imagery and LiDAR data. Conceptually, shoreline features are treated as boundary lines between land objects and water objects. Numerical algorithms have been identified and de-vised to segment and classify remote sensing imagery and LiDAR data into land and water pixels, to form and enhance land and water objects, and to trace and vectorize the boundaries between land and water ob-jects as shoreline features. A contouring routine is developed as an alternative method for extracting shore-line features from LiDAR data. While most of numerical algorithms are implemented using C++ program-ming language, some algorithms use available functions of ArcObjects in ArcGIS. Based on VB .NET and ArcObjects programming, a graphical user’s interface has been developed to integrate and organize shoreline extraction routines into a software package. This product represents the first comprehensive software tool dedicated for extracting shorelines from remotely sensed data. Radarsat SAR image, QuickBird multispectral image, and airborne LiDAR data have been used to demonstrate how these software routines can be utilized and combined to extract shoreline features from different types of input data sources: panchromatic or single band imagery, color or multi-spectral image, and LiDAR elevation data. Our software package is freely available for the public through the internet.
