| 1 | Peat molecular fossils recording paleoclimatic change and organism replacement显示文摘The occurrence of the dominant C23 n-alkane derived from bryophyte was demonstrated to be related to the cold climate, based on the GC and GC/MS analyses on a 40-cm long peat core, in which this compound exponentially varies in abundance with the depth corresponding to the well-known second Little Ice Age. Both the variation of the chemical components of modern bryophyte resulted from climatic change and the ecological data about the biological growth influenced by climate shed light on the point that the variation of this compound in the peat was related to the cold climate. This was also evidenced by the previously-reported lacustrine data. In addition, the variations of the ratios of ketones/esters and C24 n-alkene/n-alkane (C24:1/024:0) display the trend identical with that of organisms, implicating the replacement between bryophyte and monocotyledon occurring in the peat core. | XIE Shucheng & R.

| 2 | Manufacturing Titanium Metal Matrix Composites by Consolidating Matrix Coated Fibres显示文摘Titanium metal matrix composites (TiMMCs) reinforced by continuous silicon carbide fibres are being developedfor aerospace applications. TiMMCs manufactured by the consolidation of matrix-coated fibre (MCF) method offeroptimum properties because of the resulting uniform fibre distribution, minimum fibre damage and fibre volumefraction control. In this paper, the consolidation of Ti-6AI-4V matrix-coated SiC fibres during vacuum hot pressinghas been investigated. Experiments were carried out on multi-ply MCFs under vacuum hot pressing (VHP). Incontrast to most of existing studies, the fibre arrangement has been carefully controlled either in square or hexagonalarrays throughout the consolidated sample. This has enabled the dynamic consolidation behaviour of MCFs to bedemonstrated by eliminating the fibre re-arrangement during the VHP process. The microstructural evolution of thematrix coating was reported and the deformation mechanisms involved were discussed. | Hua-Xin PENGDepartment of Aerospace Engineering, University of Bristol, University Walk, Bristol, BS8 1TR, UK | 2005 | Journal of Materials Science & Technology2005，21，5： | 3 |
