Conductivity is one of the important parameters for studying the physical and chemical properties of the Earth's internal materials. Because it is sensitive to the internal conditions of the atmosphere such as temperature, fluid, chemical composition, partial melting, and redox state, it explains the material inside the Earth and other planets. Composition, structure and structure, thermal state, movement, origin and other aspects play an important role. The crust, as the outermost layer of the solid earth layer, is an important window for exploring other physical layers in the deep earth.
Recently, under the guidance of researcher Li Heping, a researcher at the Institute of Geochemistry of the Chinese Academy of Sciences’ Institute of Geochemistry of Earth’s Internal High Temperature and High Pressure, the research team members Dai Lidong, Hu Haiying, Jiang Jianjun, Hui Keshi, etc., used the YJ-3000t tight-fitting six-sided. The first high-voltage equipment and the advanced Solartron-1260 impedance spectrum analyzer performed systematic in-situ measurement of the electrical properties of typical crustal mineral rocks such as anorthosite, basalt, andesite, gabbro, and made important progress. This study obtained the quantitative functional relationships between conductivity and influencing factors (temperature, pressure, water content, melt fraction, chemical composition, etc.) of minerals and rocks, in order to explore the distribution and content of water in the crust and the redox state. Such information provides important experimental evidence and is the essential basic data for inversion of Earth's internal material composition and motion information from field magnetotelluric soundings. The element diffusion coefficient calculated from the conductivity data provides an independent constraint for the experimental results and provides important guidance for understanding the high temperature processes inside the earth, such as metamorphism, isotope chemical equilibrium, and phase transition.
This achievement was supported by the “135†Project of the Institute of Geochemistry, the 100-person Plan of the Chinese Academy of Sciences, the Special Fund for the Youth Innovation Promotion Association of the Chinese Academy of Sciences, and the National Natural Science Foundation of China (41474078, 4130406, and 41174079).
Steel Structure House refers to the
building which is structured by steel beam and column, its advantages are: 1,
light weight, high strength, the weight of Steel Structure is about 1/2 of
concrete structure. 2. Safety and reliability, good resistance to wind and
earthquake. 3. The steel structure components are made in the factory, reducing
the work load in the field, shortening the construction time, and meeting the
requirements of the industrialization. 4. The steel structure factory is made
of reliable quality, accurate size, convenient installation, and easy to
cooperate with the related parts. 5, steel can be recycled, and the environment
is less polluted when it is built and dismantled.
