金川铜镍硫化物矿床是仅次于加拿大Sudbury和俄罗斯Noril’sk-Talnakh的世界第三大在采镍矿床。金川岩体主要由含二辉橄榄岩、二辉橄榄岩、斜长二辉橄榄岩和橄榄辉石岩组成,岩相学观察表明主要造岩矿物的结晶顺序为:橄榄石→斜方辉石→... 金川铜镍硫化物矿床是仅次于加拿大Sudbury和俄罗斯Noril’sk-Talnakh的世界第三大在采镍矿床。金川岩体主要由含二辉橄榄岩、二辉橄榄岩、斜长二辉橄榄岩和橄榄辉石岩组成,岩相学观察表明主要造岩矿物的结晶顺序为:橄榄石→斜方辉石→单斜辉石→斜长石。为了进一步探讨金川岩体母岩浆成分及其分离结晶过程,本文在前人工作基础上根据主要造岩矿物结晶顺序及其电子探针成分,借助熔浆热力学软件"MELTS"的计算,获得金川岩体更为准确的母岩浆成分为:SiO248.2%,TiO21.00%,Al2O311.3%,FeO12.9%,Fe2O31.30%,MgO12.6%,CaO10.1%,Na2O1.51%,K2O0.72%,NiO0.04%。MELTS模拟计算表明金川岩体母岩浆的分离结晶经历了两个阶段,在深度约为10.9~12.5km的深部岩浆房经历了约5%的橄榄石以及约4%的斜方辉石分离结晶,并伴随硫化物熔离。在重力作用的影响下,橄榄石、斜方辉石和硫化物向下沉降,形成由下至上的分层:橄榄石-斜方辉石-硫化物-硅酸盐熔浆层,橄榄石-斜方辉石-硅酸盐熔浆层和硅酸盐熔浆层。硅酸盐熔浆首先挤出形成贫硫化物的岩体或喷出地表,之后橄榄石-斜方辉石-硅酸盐熔浆被挤入到7.6~9.2km的浅部岩浆房,经重力分异形成金川I号岩体的上部岩相带和II号岩体顶部的含辉橄榄岩。橄榄石-斜方辉石-硫化物-硅酸盐熔浆层最后被挤入金川岩体,并再次结晶出橄榄石、单斜辉石、斜长石,形成金川岩体的主要岩相和硫化物矿体。这些计算结果不仅与野外和室内岩相学观察吻合,也与硫化物熔离过程的最新研究结果相一致。 展开更多

Based on the molecular theory of non-linear viscoelasticity with constrained entanglements in polymer melts, the material functions in simple shear flow were formulated, the theoretical relations between. eta((gamma) over dot), psi (10)((gamma) over dot) and shear rate ((gamma) over dot), and topologically constrained dimension number n ' and a were derived. Linear viscoelastic parameters (eta (0) and G(N)(0)) and topologically constrained dimension number (n ' a and <(<upsilon>)over bar>) as a function of the primary molecular weight (M-n), molecular weight between entanglements (M-C) and the entanglement sites sequence distribution in polymer chain were determined. A new method for determination of viscoelastic parameters (eta (0), psi (10), G(N)(0) and J(e)(0)), topologically constrained dimension number (n ', a and v) and molecular weight (M-n, M-c and M-e) from the shear flow measurements was proposed. It was used to determine those parameters and structures of HDPE, making a good agreement between these values and those obtained by other methods. The agreement affords a quantitative verification for the molecular theory of nonlinear viscoelasticity with constrained entanglement in polymer melts. 展开更多

Electrochemical deposition and nucleation of aluminum on tungsten electrode from AlCl3-NaCl melts were studied by cyclic voltammetry, chronopotentiometry and chronoamperometry. Cyclic voltammetry and chronopotentiometry analyses showed that Al (Ⅲ) was reduced at 200℃ in two consecutive steps in an electrolyte of molten AlCl3-NaCl system with a composition 52:48 molar ratio. The current-time characteristics of nucleation aluminum on tungsten showed a strong dependence on overpotentials. Chronoamperometry showed that the deposition process of aluminum on tungsten was controlled by an instantaneous nucleation with a hemispherical diffusion-controlled growth mechanism. The results could lead to a better understanding of the AlCl3-NaCl melt system that has technological importance in electrodeposition of metals as well as in rechargeable batteries. 展开更多

Based on the atomicity and molecularity as well as the consistency ofthermodynamic properties and activities of metallic melts with their structures, the coexistencetheory of metallic melts structure involving compound has been suggested. According to this theory,the calculating models of mass action concentrations for different binary metallic melts have beenformulated. The calculated mass action concentrations agree well with corresponding measuredactivities, which confirms that the suggested theory can reflect the structural characteristics ofmetallic melts involving compound and that the mass action law is widely applicable to this kind ofmetallic melts. 展开更多

Raman spectrum of molten cryolite was recorded. Based on the new understanding of the scattering coefficients, contents of various structural entities in acidic NaF-AlF3 melts at 942-1 024 ℃ in previous research were reanalyzed. The new quantitative analysis results show that when cryolite ratio(CR) is less than 2, AlF4- is the dominant anion in the melts, and its mole fraction is about 0.70 for melts with CR=1.5 and 0.50 for melts with CR=2. When CR is more than 2.5, the mole fraction of AlF6^3- is relatively large, which is around 0.45 for melts with CR=2.5. Ionic structure of Na3AlF6-Al2O3 melts was investigated by UV-Raman spectroscopy. Octahedral AlF6^3- and tetrahedral AlF4- are proved to exist with possible partial replacement of F- by O^2-. Al2O2F4^2- with a large scattering coefficient also exists in the melts in which alumina concentration is more than 4% (mass fraction). The increase of temperature causes blue-shift of the bands in the Raman spectra. 展开更多

The gravitational field affects the evolution of multiphase media, such as rocks, soil, and alloy melts. Hypergravity increases the body force of matter, enhancing the driving force of the relative motion between substances with different densities and accelerating the evolution of multiphase media. Hypergravity experiments provide a new approach to exploring the motion of multiphase media and solving engineering problems. Hypergravity experiments have been conducted in different disciplines,such as materials science, geological science, and geotechnical engineering. However, the knowledge barriers between various research fields have caused the development of centrifuges/inflight devices and theoretical research on the mechanisms of matter in motion in hypergravity to lag behind the application of hypergravity experiments, limiting the progress in these experiments.This article systematically summarizes and proposes the fundamentals of hypergravity experiments, while the scientific challenge of the nonlinear hypergravity effect induced by high hypergravity on multiphase media evolution is clarified. Evaluation criteria are proposed for the noninertial frame effects of the centrifugal hypergravity field. The development of the high-centrifugal acceleration, large-capacity, and long-beam centrifuges are determined as the future research direction. Representative cases are used to demonstrate the effectiveness and great potential of the hypergravity experiments for the solidification of alloy melts and physical modeling. Challenges in the experimental methodology are also clarified. This paper reviews the fundamentals and applications of hypergravity experiments in various disciplines, pointing out the research direction of hypergravity experiments on multiphase media evolution. 展开更多
