西藏蛇绿岩中硅铁合金组合及成因探讨

在雅鲁藏布江蛇绿岩带的东端罗布莎蛇绿岩的铬铁矿中发现不寻常的硅铁合金组合。4种硅铁合金的理论分子式分别为Fe0.84Si2.00(Fe3Si7)、Fe7Si3、Fe6Si4以及Fe4Ti3Si2P。这些合金均选自铬铁矿石的人工重砂中，在少数颗粒中见到由3种硅铁合金组成的交生结构，明显表明这些合金的同生和同成因性。推测它们为化学反应成因,来自于核幔边界地带。

科技期刊编辑应具备的基本素质

对科技期刊质量和编辑素质的关系进行了研究，认为编辑是期刊的设计师。一本期刊从总体创意、策划选题、编审稿件到排版设计，无不体现编辑的主体意识。期刊质量的好坏，读者评价的高低都与编辑息息相关。编辑的素质关系到期刊的生存和发展。得出不断提高科技期刊编辑的素质是十分必要的结论。     

Sediment deposition from flow at low gradients into a buffer strip—a critical test of re-entrainment theory

The spatial and size distribution of sediment deposited from short periods of overland flow due to the effect of a simulated grass buffer strip was measured for low slopes of 1.6, 3.4 and 5.1%. These data were analysed so as to critically evaluate two alternative models of the process of re-entrainment of recently deposited sediment. A model of re-entrainment, previously thought to be appropriate only for a steady-state or equilibrium situation, was found to give better agreement with experiments than did a model previously used in the literature on this subject.     

Evaluation of Sea Water Quality in the Coastal Zone of Primor'e Using the Method of Microbial Indication

The response of marine microorganism community to variations in the concentrations of heavy metals in the environment is investigated for the coastal waters of Peter the Great Bay and the northern part of Primor'e. The fact of the existence and sensitivity of the individual response of plankton community microorganisms to variations in the concentrations of metals in the water under the conditions of water contamination with a complex of metals are confirmed on the basis of microbiological data and the results of their comparison to the data of chemical analysis. Microbial indication is shown to serve as an operative method of monitoring and short-term forecasting of changes in the environmental conditions of sea coastal waters. This method allows obtaining preliminary information at the stage of selecting environmental quality observation stations.     

A numerical method of viscoelastic finite element coupled with spring-block model to simulate the interaction of faults and crustal blocks

A numerical method of viscoelastic finite element coupled with spring-block model is developed to study temporal processes from the slow tectonic motion of large-scale crust to the rapid failure of small-scale faults. Our modeling demonstrates that the motion of crustal blocks is driven by forces from tectonic plate boundaries, and the deformation is distributed on faults for the stress accumulating. The coupling model generates earthquake sequences that display a magnitude-frequency scaling consistent with Gutenberg-Richter law. The frictional heterogeneities affeci earthquakes occurrence and stresses distribution of crustal blocks. Rupture of earthquakes starts at the nucleation node, and propagates bilaterally along faults with the stress triggering, release and redistribution. The failure of faults releases part of crustal stresses, the stress state of crustal blocks near fault is affected by the rupture of local segments on the fault, and the stress state of crustal blocks far away from the fault is controlled by the seismic activity of the whole fault.
