以喷雾干燥 H2还原法制备的纳米级90W 7Ni 3Fe复合粉末为原料,针对不同稀土元素La,La Y,Y含量对90W Ni Fe合金性能和显微结构的影响进行了研究。
Based on the problem reduction method, robustness problem of discrete multi-agent system in the ideal distributed environment was reduced and transformed into that of single agents and discrete control processes. So the problems were simplified and research difficulty degree was descended.
In this paper, attribute reduction method based on rough set is used to pretreatthe historical data of various period, and the forecasting model based on supportvector machine is used to calculate the power supply-demand index of warningstatus from 2005 to 2008, then forecast the situation of power supply-demandaccording to warning degree.
Using the direct and potential symmetry reduction method (CK method), the generalized Camassa-Holm equation with full nonlinear terms, its exact solutions and the effect of nonlinear terms are studied.
Bifurcation of Cahn-Hilliard-Schlogl reaction diffusion equations,in which the reaction term is Schlogl's one and the diffusion term is governed by Cahn-Hilliard's generalized diffusion law,are studied by means of Lyapunov-Schmidt reduction method. singularity theory and perturbation method.
It's well known that the symmetry reduction method related to group theory, such as Lie point symmetry method, generalized symmetry, conditional symmetry, generalized conditional symmetry and etc, is an effective tool to the study of the exact solutions for the nonlinear Partial Differential Equations.
The Pt-Sn-B/carbon nanotubes (CNTs) catalyst was prepared by impregnation-chemical reduction method.
