In this study, La2O3 was investigated as an additive to TiC/W composites. The composites were prepared by vacuum hot pressing, and the microstructure and mechanical properties of the composites were investigated. Experimental results show that the grain size of the TiC/W composites is reduced by TiC particles. When 0.5 wt.% La2O3 is added to the composites, the grain size is reduced further. According to TEM analysis, La2O3 can alleviate the aggregation of TiC particles. With La2O3 addition, the relative density of the TiC/W composites can be improved from 95.1% to 96.5%. The hardness and elastic modulus of the TiC/W ＋ 0.5 wt.% La2O3 composite are little improved, but the flexural strength and the fracture toughness increase to 796 MPa and 10.07 MPa·m^1/2 respectively, which are higher than those of the TiC/W composites.

Using next-generation sequencing technology alone, we have successfully generated and assembled a draft sequence of the giant panda genome. The assembled contigs (2.25 gigabases (Gb)) cover approximately 94% of the whole genome, and the remaining gaps (0.05 Gb) seem to contain carnivore-specific repeats and tandem repeats. Comparisons with the dog and human showed that the panda genome has a lower divergence rate. The assessment of panda genes potentially underlying some of its unique traits indicated that its bamboo diet might be more dependent on its gut microbiome than its own genetic composition. We also identified more than 2.7 million heterozygous single nucleotide polymorphisms in the diploid genome. Our data and analyses provide a foundation for promoting mammalian genetic research, and demonstrate the feasibility for using next-generation sequencing technologies for accurate, cost-effective and rapid de novo assembly of large eukaryotic genomes.

Chronology and geochemistry of the volcanic rocks in Woruo Mountain region,Northern Qiangtang depression:Implications to the Late Triassic volcanic-sedimentary events

引用

Science China Earth Sciences 2008年第2期51卷 194-205页

作者： WANG Jian FU XiuGen chen WenXi WANG ZhengJiang TAN fuwen chen Ming ZHUO JieWen Chengdu Institute of Geology and Mineral Resources Chengdu 610082China Graduate Department of Chinese Academy of Geological Sciences Beijing 100037China

A suite of sedimentary-volcaniclastic rocks intercalated with the volcanic rocks unconformably overlies the Triassic Xiaochaka Formation in the Woruo Mountain region, Qiangtang Basin, northern Tibet. The vitric tuff from the base of these strata gives a SHRIMP zircon U-Pb age of 216 ± 4.5 Ma, which represents the age of the Late Triassic volcanic-sedimentary events in the Woruo Mountain region, and is consistent with that of the formation of the volcanic rocks from the Nadi Kangri Formation in the Nadigangri-Shishui River zone. There is a striking similarity in geochemical signatures of the volcanic rocks from the Woruo Mountain region and its adjacent Nadigangri-Shishui River zone, indicating that all the volcanic rocks from the Qiangtang region might have the same magmatic source and similar tectonic setting during the Late Triassic. The proper recognition of the Late Triassic large-scale volcanic eruption and volcanic-sedimentary events has important implications for the interpretation of the Late Triassic biotic extinction, climatic changes and regressive events in the eastern Tethyan domain, as well as the understanding of the initiation and nature, and sedimentary features of the Qiangtang Basin during the Late Triassic-Jurassic.

Design of robust non-fragile H-infinity controllerbased on Delta operator theory

控制理论与应用（英文版） 2007年第4期5卷 404-408页

作者： Ruiquan LIN fuwen YANG Qiugang chen College of Electrical Engineering and Automation Fuzhou University Fuzhou Fujian 350002 China

Considering that the controller parameters are of additive norm-bounded uncertainties when realized, a design method of robust non-fragile H-infinity controller for uncertain systems based on Delta operator theory is illustrated in this paper. A sufficient and necessary condition of the existence for the controller is given, which is presented in LMI forms. Finally, the designed method is used in the speed control system of a permanent magnet linear synchronous motor （PMLSM）. With the designed controller, the resulting speed closed-loop system is still stable and has the expected Hinfinity performance even if the sample period is reduced and the parameters of the controller and the controlled object are varied. The results show that the designed method is effective.

采用高能球磨手段制备了W-10%TiC(质量分数,下同)纳米复合粉体,并采用热压方法烧结成致密块体,研究了高能球磨、烧结温度、烧结时间及烧结压力对复合材料致密度和力学性能的影响。结果表明:高能球磨后,复合粉体的颗粒形状近似球形,粒径均匀,平均粒径为100nm,并且纳米复合粉体的烧结温度大大降低,其原因是粉体的颗粒细小、扩散系数高、表面能高等性质及球磨过程中少量Fe,Ni杂质的引入。对所制备纳米粉体而言,较合适的烧结工艺为:1700℃,30MPa压力下烧结60min,在此工艺条件下制备的复合材料的致密度达到98.4%,抗弯强度和断裂韧性分别达到:681MPa,6.24MPa·m1/2。

南岭地区地质工作程度较高,但近20年来地质找矿与科研工作投入不足,导致南岭地区一些优势矿产储量消耗过快,影响到矿业的可持续发展。近年来,南岭地区芙蓉锡矿等一批新矿产地和八仙脑式破碎带蚀变岩型钨矿等一批新矿床类型的发现,充分说明,只要认真开展成矿预测研究,配合地质找矿实践,在南岭地区取得找矿突破的可能性并不亚于西部地区。因此,目前迫切需要加强对南岭地区成矿规律的深入研究,尤其是加强矿床成矿系列、成矿体系、成矿物质来源及其超常规富集成矿机制、大型超大型矿床与矿集区、常规优势矿产与非优势矿产之间相关关系等方面的创新性研究与探索,为危机矿山“探边摸底”和新矿产地的发现提供理论指导和科学依据。
