求助Ei核心和非核心检索！！！
|

|
有困惑！ 本人有一篇论文被EI收录，可以在统计的时候中国科学技术信息研究所认为属于：非核心收录。我打电话对方说是：通过高级检索设定范围，不在核心的范围之内，请高人明示：如何通过高级检索设定检索范围？我的论文到底是Ei核心还是非核心收录，谢谢！！！ 第一作者：peizhong feng 题目：effect of high-tempreture 来源：Journal of alloys and compounds 年卷：2009,473:185-189 Accession number: 20091011948319 |

Accession number: 20091011948319 Title: Effect of high-temperature preoxidation treatment on the low-temperature oxidation behavior of a MoSi2-based composite at 500 °C Authors: Feng, Peizhong1 ; Wang, Xiaohong1 ; He, Yaqiong1 ; Qiang, Yinghuai1 Author affiliation: 1 School of Materials Science and Engineering, China University of Mining and Technology, Xuzhou, 221116, China Corresponding author: Feng, P. (fengroad@163.com) Source title: Journal of Alloys and Compounds Abbreviated source title: J Alloys Compd Volume: 473 Issue: 1-2 Issue date: April 3, 2009 Publication year: 2009 Pages: 185-189 Language: English ISSN: 09258388 CODEN: JALCEU Document type: Journal article (JA) Publisher: Elsevier Ltd, Langford Lane, Kidlington, Oxford, OX5 1GB, United Kingdom Abstract: In order to investigate the effect of protective scale formed by high-temperature preoxidation process on the low-temperature oxidation behavior of a MoSi2-based composite, the oxidation experiment at 500 °C in air was performed by employing X-ray diffraction, scanning electron microscopy and thermo-gravimetric analysis. The results show that the preferred low-temperature oxidation/pest sites are the externally cylindrical face of the sample without high-temperature preoxidation treatment. With the prolonging of oxidation, the pest advances radially in cylinder sample. When the oxidation time reaches 288 h, the mass gain is arrived at 0.466 mg cm-2. A glass protective scale is formed on the surface of material by high-temperature preoxidation treatment. The scale can play a role of barrier layer of oxygen. This results in a reduced rate of low-temperature oxidation, and the pest is restrained. When the oxidation has been for 288 h, the mass gain of high-temperature preoxidation sample is only -0.007 mg cm-2, and the surface microstructure is still smooth, without undergoing the pest oxidation. High-temperature preoxidation treatment can effectively restrain the low-temperature oxidation behavior, and avoid the pest phenomenon of MoSi2-based composite. © 2008 Elsevier B.V.
