Null 包大杰1 (1.上海柴油机厂,上海,200432) 摘要: 问:何谓钢铁中全碳量(总碳量)和游离碳?答:碳在钢,铁中主要以化合状态和游离状态存在.在钢中主要以铁的碳化物如:Fe3C,Fe23C6等以及与某些合金元素的碳化物如:Mn3C,WC,TiC,MoC,VC,Cr3C2,Cr6C2等形式存在,统称为化合碳,钢中很少有游离碳.在铁中碳除以化合碳存在外,还以游离状态(石墨碳)存在,而且是主要形式.但是在白口铁中则多以碳化铁(Fe3C)形式存在. [全文内容正在添加中] ......
J. Cent. South Univ. (2017) 24: 2438-2448 DOI: https://doi.org/10.1007/s11771-017-3655-x Multi-scale regionalization based mining of spatio-temporal teleconnection patterns between anomalous sea... by existing work. Therefore, in this study, the multi-scale regionalization is embedded into the spatio-temporal teleconnection pattern mining between anomalous sea and land climatic events. A modified......

Faculty of Science, Jiangsu... modes, the matrix-based system reliability method (MSR method) was studied. With multi-scale method, the slope system was decomposed into many parallel sub-systems which were regarded as "super......
environments (AIDE) was proposed based on a biological immune response principle. The dynamic process of artificial immune response with operators such as immune cloning, multi-scale variation... clonal proliferation was proposed. In addition, with the introduction of multiple populations and multi-scale variation, the algorithm can well maintain the population diversity during the dynamic......
to be an efficient means of numerically simulating of multi-scale rock and soil media and studying the mechanical properties of soil samples. Key words: meso particle; three-dimensional micromorphology; spherical harmonic function; random reconstruction; multi-scale 1 Introduction Natural rocks and soil are composed of particles of different sizes cemented to each other. For instance, soil-rock......
