| 2 | Discovery of double-peaking potassic volcanic rocks in Langshan Group of the Tanyaokou hydrothermal- sedimentary deposit, Inner Mongolia, and its indicating significance显示文摘It is revealed that the protolith of gray-light brown potash-feldspar-leucogranulites and granulites in the 2nd formation of the LG in Tanyaokou deposit are quartz kerotophyre of synsedimentary eruption based on the following facts and features: (1) The rocks look compact and homogeneous without obvious crystals with naked eyes; (2) they contain blastoporphyritic or glomeroporphyritic and blasto-crystalloclastic crystals consisting of quartz with wavy extinction and albite with obvious alteration and deformation; (3) they also contain radiated and fibrous blasto-microspherulitic texture and swallow-tailed bifurcate and blasto-hollow-skeleton crystal texture, representing the rapid cooling characteristic of the magma during submarine volcanic eruption; (4) the major chemical compositions of the rocks are: SiO2 = 70.80%―76.00%, K2O (4.83%―6.22%)>Na2O(2.78%―3.80%), and K2O+Na2O = 8.63%―9.00%; and (5) their petro-chemical diagrams indicate that they are volcanic rocks. Together with the characteristic that they occur in the same sequence with potassic spilite (SiO2 = 46.12%―50.68%, K2O = 4.23%―5.93%>Na2O = 2.15%―3.14%, K2O+Na2O = 6.51%―8.08%), it can be confirmed that the vol-canics occurring in the 2nd Formation of the LG in Tanyaokou district are double-peaking potas-sic volcanic rocks. The discovery, together with the tuffs with ore minerals and the distribution of lead isotopic as well as the value of Co/Ni of pyrites >1 showing the obvious endogenic metali-zation, can prove that the Tanyaokou deposit is an untypical SEDEX-type deposit formed in the extension fault basin in the Mesoproterozonic aulacogen of the northern margin of the North China Platform, and its metallogenesis is related to the synsedimentary volcanic activities and the hydrothermal exhalation, and both the ore-forming material source and volcanics came from mantle or lower crust. These facts mentioned above, together with the meta-volcanic rocks (double-peaking) found in the Dongshengmiao and Huogeqi districts and the host stratigraphic sequence of LG, can further prove that the Mesoproterozoic aulacogen of passive continental margin of Langshan-Zhaertaishan area had been unevenly expanded. This provides some in-formation and new approaches for the study on tectonic-hydrothermal events in Lang-shan-Zhaertaishan aulacogen and their evolutionary process, hydrothermal dynamical source, the relationship between the volcanic activities and the ore-forming process, the regional ore-forming regularity as well as for the correlation with the similar deposits abroad. | PENG Runmin1, ZHAI Yusheng1, WANG Zhigang2 & HAN Xuefeng2 1.

| 3 | Hepatic blood inflow occlusion without hemihepatic artery control in treatment of hepatocellular carcinoma显示文摘AIM:To investigate the clinical significance of hepatic blood inflow occlusion without hemihepatic artery control (BIOwHAC) in the treatment of hepatocellular carcinoma (HCC).METHODS:Fifty-nine patients with HCC were divided into 3 groups based on the technique used for achieving hepatic vascular occlusion:group 1,vascular occlusion was achieved by the Pringle maneuver (n=20);group 2,by hemihepatic vascular occlusion (HVO) (n=20);and group 3,by BIOwHAC (n=19).We compared the procedures among the three groups in term of operation time,intraoperative bleeding,postoperative liver function,postoperative complications,and length of hospital stay.RESULTS:There were no statistically significant differences (P > 0.05) in age,sex,pathological diagnosis,preoperative Child's disease grade,hepatic function,and tumor size among the three groups.No intraoperative complications or deaths occurrred,and there were no significant intergroup differences (P > 0.05) in intraoperative bleeding,hepatic function change 3 and 7 d after operation,the incidence of complications,and length of hospital stay.BIOwHAC and Pringle maneuver required a significantly shorter operation time than HVO;the difference in the serum alanine aminotransferase or aspartate aminotransferase levels before and 1 d after operation was more significant in the BIOwHAC and HVO groups than in the Pringle maneuver group (P < 0.05).CONCLUSION:BIOwHAC is convenient and safe;this technique causes slight hepatic ischemia-reperfusion injury similar to HVO. | Shan Jin,Department of General Surgery,Affiliated Hospital of Inner Mongolia Medical College,Hohhot 010050,Inner Mongolia Autonomous Region,China Chao-Liu Dai,Department of Hepatobiliary Surgery,Shengjing Hospital,China Medical University,Shenyang,Liaoning Province,China | 2010 | World Journal of Gastroenterology2010，16，46： | 6 |
| 4 | Integrating MODFLOW and GIS technologies for assessing impacts of irrigation management and groundwater use in the Hetao Irrigation District,Yellow River basin显示文摘Due to severe water scarcity, water resources used in agricultural sector have been reduced markedly in Hetao irrigation district. Application of water-saving practices (WSPs) is required for the sustainable agricultural development. The human activities including WSPs and increase of groundwater abstraction can lower down the groundwater table, which is helpful to the salinity control. Meanwhile, an excessively large groundwater table depth may result in negative impact on crop growth and fragile ecological environment. In this paper, the Jiefangzha irrigation system in Hetao irrigation district was selected as a typical area, a groundwater flow model based on ArcInfo Geographic Information System (GIS) was developed and implemented to quantify the effect of human activities on the groundwater system in this area. The preand post-processing of model data was performed efficiently by using the available GIS tools. The time-variant data in boundary conditions was further edited in Microsoft Excel with programs of Visual Basic for Application (VBA). The model was calibrated and validated with independent data sets. Application of the model indicated that it can well describe the effect of human activities on groundwater dynamics in Jiefangzha irrigation system. | XU Xu1,2, HUANG GuanHua1,2 & QU ZhongYi3 1 Center for Agriculture Water Research, China Agricultural University, Beijing 100083, China 2 Chinese-Israeli International Center for Research and Training in Agriculture, China Agricultural University, Beijing 100083, China 3 Water Conservancy and Civil Engineering College, Inner Mongolia Agricultural University, Hohhot 010018, China | 2009 | Science China(Technological Sciences)2009，52，11： | 6 |
| 5 | Exchange bias for ferromagnetic/antiferromagnetic bilayers with the uniaxial anisotropy being misaligned with the exchange anisotropy显示文摘Using the principle of minimal energy and S-W model,the exchange bias for ferromagnetic/antiferro-magnetic bilayers has been investigated when the uniaxial anisotropy is misaligned with the exchange anisotropy. According to the relation between the energy of the bilayer and the orientation of ferro-magnetic magnetization,it is found that the bilayer will be in the monostable state or bistable state when the external field is absent in the initial magnetization state. The monostable state or bistable state of the bilayer,which determines the angular dependence of exchange bias directly,is controlled by the competition between the exchange anisotropy and uniaxial anisotropy. When the applied field is parallel to the intrinsic easy axes and intrinsic hard axes,one of the switching fields of the hysteresis loop shows an abrupt change,while the other keep continuous by analyzing the magnetization reversal processes. Consequently,the exchange bias field and the coercivity will show a jump phenomenon. The numerical calculations indicate that both the magnitude and direction of the exchange anisotropy will significantly affect the angular dependence of exchange bias. The jump phenomenon of exchange bias is an intrinsic property of the bilayer,which is dependent on the interfacial exchange-coupling constant,the orientation of the exchange anisotropy,the thickness and uniaxial anisotropy constant of the ferromagnetic layer. | BAI YuHao1 & YUN GuoHong1,2 1 College of Physical Science and Technology,Inner Mongolia University,Hohhot 010021,China 2 Key Laboratory of Physics and Chemistry of Functional Materials,College of Physics and Electronic Information,Inner Mongolia Normal University,Hohhot 010022,China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 5 |

| 8 | A density-dependent matrix model and its applications in optimizing harvest schemes显示文摘Based on temporal data collected from 36 re-measured plots, transition probabilities of trees from a diameter class to a higher class were analyzed for the broadleaved-Korean pine forest in the Changbai Mountains. It was found that the transition probabilities were related not only to diameter size but also to the total basal area of trees with the diameter class. This paper demonstrates the development of a density-dependent matrix model, DM2, and a series of simulations with it for forest stands with different conditions under different harvest schemes. After validations with independent field data, this model proved a suitable tool for optimization analysis of harvest schemes on computers. The optimum harvest scheme(s) can be determined by referring to stand growth, total timbers harvested, and size diversity changes over time. Three user-friendly interfaces were built with a forest management decision support system FORESTAR(R) for easy operations of DM2 by forest managers. This paper also summarizes the advantages and disadvantages of DM2. | Guofan Shao, WANG Fei, DAI Limin, BAI Jianwei & LI Yingshan Department of Forestry and Natural Resources, Purdue University, West Lafayette, IN 47907, USA Institute of Applied Ecology, Chinese Academy of Sciences, Shenyang 110016, China Inner Mongolia Agriculture University, Hohhot 010019, China Academy of Forest Inventory and Planning, State Forestry Administration, Beijing 100714, China | 2006 | Science China(Technological Sciences)2006，49，z1： | 4 |

| 16 | Microstructure evolution of laser rapidly solidified Al-Mn alloys显示文摘A series of laser surface remelting experiments of Al-1.1, 3.2 and 5.6 wt% Mn alloys has been conducted using a 5 kW CW CO2 laser, and the microstructures of samples have also been investigated. The experimental results show that no apparent eutectic growth appears in the whole growth rate range for Al-3.2 wt% Mn alloy under laser rapid solidification condition, and the microstructure grows in the form of α(Al) cell/dendrite. With the increase of growth rate, the microstructures of Al-5.6wt%Mn alloy change from Al6Mn dendrite to α(Al) +Al6Mn eutectic, α(Al) cellular/dendrite and segregation-free solid solution. The critical rates of Al-1.1, 3.2 and 5.6 wt% Mn alloys to attain absolute stability are 44.1, 134.6 and 230.1 mm/s respectively, and a reasonable agreement has been found between the experimental results and those calculated according to Mullins-Sekerka's theory. | YANG Sen, HUANG Weidong, LIU Wenjin and ZHOU Yaohe(1.

| 19 | Sequence Stratigraphy and Tectonic Environment of the Chartai Group,Inner Mongolia显示文摘The Middle Proterozoic Chartai Group separated by two unconformities consists of three depositional se-quences: the Shujigou Formation-Zenglongchang Formation (DS Ⅰ), the Agulugou Formation (DS Ⅱ), andthe Liuhongwan Formation (DS Ⅲ). The carbonate platform and back-platform basin are the basic environ-ment model of the Chartai Group. The syndepositional faults on the oceanward side of the carbonate platformand large-scale slumping in the soft sediments are important marks of facies tracts. The newly establishedZenglongchan uplifting, an epeirogenetic uplifting, plays an important role in the formation of thepalaeogeographic framework of the Chartai Group. The stratigraphic correlation between the Chartai Groupand the Bayan Obo Group is made for the first time by using sequence stratigraphic principle and model estab-lished by P.R. Vail. The Chartai Group, which was deposited on the northern passive continental margin of theNorth China platfom, represents the platform cover. | Qiao Xiufu Yao Peiyi Wang Chengshu Tan Lin Zhu Shenyu Zhou Shengde Zhang Yuqing Institute of Geology,Chinese Academy of Geological Sciences, Beijing Regional Geological Survey Party,Geological Bureau of Inner Mongolia,Hohhot Sun Sheping | 1991 | Acta Geologica Sinica(English Edition)1991，65，3： | 1 |
