Mechanism of low thermal conductivity of xonotlite-silica aerogel nanoporous super insulation material

引用

Journal of University of Science and Technology Beijing 2008年第5期15卷 649-653页

作者： Hailong yang Wen Ni deping Chen Guoqiang Xu Tao Liang Li Xu Civil and Environmental Engineering School University of Science and Technology Beijing Beijing 100083 China

In an effort to incorporate the low thermal conductivity of the silica aerogel and the superior structure strength of the xonotlite,a composite material of these two was produced. It was synthesized under vacuum condition and dried by supercritical drying technique. The thermal conductivity of the new material,which is at 298K with the gas pressure ranging from 1.01×10^5 to 1×10^-2 Pa,was measured using the transient hot-strip method. The mechanism of the low thermal conductivity was studied. The results indicate that the low thermal conductivity mainly results from the significant decrease of gaseous thermal conductivity of the new material due to the restriction of the motion of gas molecules in its fine structures. The formation of the fine structures is because the new material takes the pore structure of the silica aerogel which consists of mainly nanometer-sized pores.

The macroscopic and microscopic magnetic properties for amorphous and nanocrystalline Fe73.5Cu1Nb3-Si13.5B9 powder have been investigated and their giant mag-neto-impedance (GMI) effect is reported for the first time. The experimental results show that powder sample annealed at 510℃ possesses the optimum soft magnetic properties. However, the maximum longitudinally driven GMI (LDGMI) ratio (about 52%) is found in the sample annealed at 600℃. This means that the LDGMI ratio depends on not only their magnetic properties but also their electric properties.

Deep Structural Framework and Genetic Analysis of Gold Concentration Areas in the Northwestern Jiaodong Peninsula, China： A New Understanding based on High-Resolution Reflective Seismic Survey

引用

Acta Geologica Sinica(English Edition) 2018年第5期92卷 1823-1840页

作者： YU Xuefeng SHAN Wei XIONG Yuxin GENG Ke SUN Yuqin CHI Naijie GUO Baokui LI Dapeng LI Hongkui SONG Yingxin yang deping Shandong Key Laboratory of Geological Processes and Resource Utilization in Metallic Minerals Jinan 250013 Shandong China Key Laboratory Of Gold Mineralization Processes and Resources Utilization Minister of Land and Resources Shandong Institute of Geological Sciences

The gold concentration areas in the northwestern Jiaodong Peninsula constituted an important gold metallogenetic region in Eastern China during the Mesozoic. The deep geological bodies＇ texture characteristic is important for exploring the resources thoroughly and understanding the metallogenic process. The detailed textures were revealed using high-resolution seismic profiles through the three major ore-controlling structures-Sanshandao fault zone, Jiaojia fault zone and Zhaoping fault zone. This study aims to establish a deep structural framework of this area. Based on their formation mechanism, the fault structures developed in the area can be divided into regional and local fault structures. The structural styles are characterised by superimposing their compressional, strike-slip and extensional multi-stage activities. The crust is cut by vertical structures corresponding to a left-lateral strike-slip fault system on the surface. Nearby these structures are the arc-shape structures formed by multi-stage magma intrusions into the upper crust. Bounded by the Tancheng–Lujiang and Muping–Jimo fault zones, the current Jiaodong block, developed a series of NE-trending strike-slip fault systems, was probably formed by the assemblage of several obliquely aligned blocks. The intensive magmatism and hydrothermal activity between the blocks induced large-scale mineralisation. It provides a new angle of view for understanding the cratonic destruction and large ore-concentration formed during the Mesozoic.
