1A 780-year record of explosive volcanism from DT263 ice core in east Antarctica显示文摘从极的冰表恢复的冰核心从爆炸暴烈的爆发收到了并且保存硫磺的酸放射性尘埃, DT263 冰核心从东方 Antarcticlocation 被检索。冰核心用年度层作为 780 年(1215-1996 A.D ) 数和暴烈的 timestratigraphic 地平线的联合被标明日期。冰核心记录在约 1460 的时期期间表明那 - 1800 A.D,累积是比层次在以前并且在这个时期以后严厉地低的。这个时期与最近的 neoglacial 与气候的事件一致,“很少冰川期(LIA ) ”,那在众多的北半球代理和历史性的记录被发现了。non-sea-salt SO_2 集中在 DT263ice 核心显示十七个暴烈的事件。与那些相比从以前的南极冰核心,重要差异在几个著名事件的相对暴烈的流动在这些记录之间被发现。在这些记录之中的差异可以被差别在在冰核心上加亮本地冰河学的潜在的影响的表面地形学,累积率,雪飘移和分发解释暴烈的记录,分析技术为硫酸盐测量使用了,等等。在中间、高的南部的纬度的暴烈的爆发在低纬度比那些更强烈地在南极雪中影响暴烈的记录。ZHOU-Liya LI Yuansheng Jihong Cole-dai TAN Dejun SUN Bo REN Jiawen WEI Lijia WANG Henian 2006Chinese Science Bulletin2006,51,22:9
2Hydrogen isotope geochemistry of lherzolitic shergottite in Martian meteorite GRV99027 from the Grove Mountains in Antarctica显示文摘Hydrogen isotopic composition was measured using an ion microprobe for lherzolitic shergottite in Martian meteorite GRV 99027 from the Grove Mountains in Antarctica. The D/H ratios of phosphate whitlockites were analyzed and water concentrations of tested points were calculated. The result show that their δ D values vary from +1300‰ to +4700‰, and water contents from 0.04 wt% to 0.43 wt%. Comparing the results with the hydrogen isotopic compositions of whole rock, hydrous miner- als and phosphates in SNC meteorites indicates that water highly enriched in deuterium is a unique feature of Martian meteorites, especially the phosphates prominent. It is interpreted as the result of isotopic exchange between magmatic water and Martian crustal fluids. The high D/H ratios observed in GRV 99027 phosphates indicate that they have hydrogen isotopic compositions similar to those of apatite in other Martian meteorites. The results further con- firmed the association of GRV 99027 with the Martian meteorite group.WANG Henian HSU Weibiao GUAN Yunbin LIANG Ying 2006Chinese Science Bulletin2006,51,16:5
3Kinetic model for the smectite to illite transformation in active geothermal systems显示文摘The smectite to illite transformation in active geothermal systems of New Zealand can be simulated by a first_order reaction kinetic model, which provides direct estimates about the minumum ages of active geothermal systems themselves. The derived kinetic values show that the smectite to illite transformation is sensitive to both temperature and time.Ji Junfeng P. R. L.

4Estimating leaf mercury content in Phragmites australis based on leaf hyperspectral reflectance显示文摘Introduction:Highmercury(Hg)concentrations affect the chlorophyll in leaves,therebymodifying leaf spectra.Hyperspectra is a promising technique for the rapid,nondestructive evaluation of leaf Hg content.In this study,we investigated Hg contents and reflective hyperspectra of reed leaves(Phragmites communis)in a gold mining(Jilin province,China).Spectral parameters sensitive to Hg content were identified through basic spectral transformations,continuous wavelet transformation(CWT),and spectral indices techniques.Leaf Hg inversion models were developed using stepwise multiple linear regression,partial least squares regression,and random forest algorithms.Outcomes:The results indicated that:1)leaf Hg content decreased with increasing distance from the mine:Jiapigou(JPG)>Erdaocha(EDC)>Laojingchang(LJC)>Erdaogou(EDG)>Lingqian(LQ)>Weishahe(WSH).2)Hg–sensitive wavelengths were primarily in the visible region;CWT increased the correlation between hyperspectral data and leaf Hg content,and improved the regression and accuracy of inversion;3)the continuumremoval–CWT–stepwise multiple linear regression was better for estimating low leaf Hg content;while the differential spectral index–partial least squares regression was better for estimating high leaf Hg content.Conclusion:These hyperspectral inversion methods could be used for rapid,nondestructive monitoring of wetland plants.Weiwei Liu Mengjie Li Manyin Zhang DaanWang Ziliang Guo Songyuan Long Si Yang Henian Wang Wei Li Yukun Hu Yuanyun Wei Hongye Xiao 2020Ecosystem Health and Sustainability2020,6,1:2
5OPTICAL OPTIMIZATION FOR LIQUID CRYSTAL TEST BY LASER-CCD SYSTEM显示文摘For the narrowband of liner charge-coupled device (CCD) receiver and the imaging rule thatcylindrical lens system can compress round facula into narrow and long one, the system is simplified andlight force can concentrate on a strip facula. Considered the effective CCD length and selection of lensparameters, the system can be optimized. Correspondingly to the CCD pixels, the ray is composed ofmuch angle information. By widening the parallel ray or increasing the lens aperture, luminous flux canbe ensured when oblique incidence. Meanwhile, the effective working range can also be improved. Basedon the experimental data, cylindrical system could be applied in accurate angle measurement. It has beenproved feasible that the cylindrical system can be used in anchor behavior study for liquid crystal (LC)case. The low-power He-Ne laser cylindrical system can carry out the previous effect in high power laserspherical system.Chang Ying Zhu Henian Zhang Ziliang Yang Changxi 2005Chinese Journal of Mechanical Engineering2005,18,3:2

15Kerogen——as a sort of organic bearer of gold in gold-bearing formations显示文摘Organic component, organic carbon and gold content analyses were used to study the relationship between gold mineralization and organic matter in major host rocks of three different chronological gold-bearing formations of South China. The results show that the organic matter of host rocks in various chronological major gold-bearing formations of South China has associated with gold mineralization in genesis. There is a positive correlation between gold and organic carbon in the host rocks of gold-bearing formations. Gold element was mainly enriched in insoluble organic matter——kerogen. Gold content of the kerogen is commonly higher from a few tens to several hundred times than that of the whole rocks, up to 5%—40% gold of the whole rocks. Gold remaining in the kerogen was considered an organic group of the kerogen to combine with ionic gold in solution through surface absorption, ion exchange complex reaction and chelation so that the kerogen could have become an important sort of organic bearerKai Hu Jianping Zhai Yingjun Liu Henian Wang 1999Chinese Science Bulletin1999,44,11:1

20Effect of forest on sediment yield in North China显示文摘Forest-sediment relationship is a hot and important issue in Ecohydrology studies.China has implemented many large-scale reforestation programmes in the last decades to address the growing soil erosion and desertification.In this study,we made statistical and graphic analyses on the long-term hydrological data of the 39 watersheds in the rocky mountain area of the North China,and then we were able to analyze the effect of forest on sediment yield.Our results show that the effect is weak in the lees-precipitation regions(when MAP<500 mm).And in the more-precipitation regions(when MAP>500 mm),the impact of forest on reducing sediment yield is different with the varied forest coverage(f),the relationship between the sediment yield and forest coverage show a quadratic polynomial.Yu Xinxiao Wang Henian Xin Zhongbao Lv Xizhi 2013International Soil and Water Conservation Research2013,1,1:1
