| 1 | Geochemistry of Ore-bearing Lamprophyre from the Cu-Ni Deposit in Dhi Samir,Yemen显示文摘Magmatic Cu-Ni 硫化物存款通常与 mafic-ultramafic 岩石被联系,煌斑岩是 Cu-Ni 硫化物存款的包围岩石之一,这没被报导。然而,在也门的 Dhi Samir 存款是在煌斑岩堤被招待的 Cu-Ni 存款的一个稀罕例子。在这篇论文,全面研究在 Dhi Samir 区域为 Cu-Ni-bearing 岩石在岩石学,石油化学和同位素地球化学上被做,结果证明与 Cu-Ni orebodies 有关的黑暗岩石是钠弱的钾并且属于计算碱的系列煌斑岩,特别 camptonite,由充实的碱,铁和钛描绘了。当高地力量元素稍微弄空时,在这些岩石 large-ion-lithophile,元素显然被集中,显示出清楚的否定异例 Ta 和 Nb,和 Ti 的弱缺乏。REE 是很,高度(225.67290.05 ppm ) 和 REE 分区弯扁平、使权利倾向,与低否定 Eu 异例展示一个充实 LREE 的模式。magmatic 来源区域的学习显示岩石有低(87Sr/86Sr ) 并且高 Nd (t) ,和岩浆可能从充实的披风被导出我(EM-I ) 结束成员。在锆石 U-Pb 同位素标明日期上基于 LA-ICPMS,在 Dhi Samir 采矿区域的煌斑岩有 602 precipi 的年龄吗?? | ZUO Liyan PEI Rongfu SHUAI Kaiye YANG Fengqi ZHU Riwei ZHANG Liemeng | 2011 | Acta Geologica Sinica(English Edition)2011，85，1： | 2 |

| 17 | Occurrence and Chemical Control Techniques of Rice Black-streaked Dwarf Disease in Rongshui County显示文摘The chemical control technologies of southern rice black-streaked dwarf disease in hybrid rice were studied in Rongshui County,Guangxi,through a combination of investigation,observation and experiments.Three treatments were set up,namely,no water,shallow water and deep water,and each of which had a treatment area of 67 m^(2).Each treatment was sprayed once with 40 g of 200 million/g Bacillus subtilis wettable powder and 20-30 g of 25%pymetrozine wettable powder per 667 m^(2) in a mixture with 30 kg of water.On the day of spraying,100 diseased rice hills in each treatment were marked for field observation.The test results showed that the control of southern rice black-streaked dwarf disease should be done by draining the field water and spraying the mixture of B.subtilis and pymetrozine evenly,and a better effect can be achieved by keeping the field moist for 6-7 d after spraying. | Riwei HUANG Rongqing MO Changhua TANG Zishuai SHANG | 2021 | Agricultural Biotechnology2021，10，6： | 0 |
| 18 | Fractal analysis of polyethylene catalysts surface morphologies based on wavelet transform modulus maxima method显示文摘Surface morphologies of supported polyethylene (PE) catalysts are investigated by an approach combining fractal with wavelet. The multiscale edge (detail) pictures of catalyst surface are extracted by wavelet transform modulus maxima (WTMM) method. And, the distribution of edge points on the edge image at every scale is studied with fractal and multifractal method. Furthermore, the singularity intensity distribution of edge points in the PE catalyst is analyzed by multifractal spectrum based on WTMM. The results reveal that the fractal dimension values and multifractal spectrums of edge images at small scales have a good relation with the activity and surface morphology of PE catalyst. Meanwhile the catalyst exhibiting the higher activity shows the wider singular strength span of multifractal spectrum based on WTMM, as well as the more edge points with the higher singular intensity. The research on catalyst surface morphology with hybrid fractal and wavelet method exerts the superiorities of wavelet and fractal theories and offers a thought for studying solid surfaces morphologies. | CEN Wei YANG ShiFeng XUE Rong XU RiWei YU DingSheng | 2007 | Science China Chemistry2007，50，3： | 0 |
