国际地理联合会区域会议在智利圣地亚哥召开(英文)

The IGU Regional Conference (UGI 2011) was held on November 14-18, 2011 in Santiago, Chile. It was organized by the Military Geographic Institute (IGM). Nearly 1000 geographers across the world participated in this event. The Geographical Society of China (GSC) sent a delegation consisting of more than 40 members to attend the conference.     

Comprehensive tests on rising height of capillary water for coarse grained soil

According to the comprehensive tests on the rising height of capillary water for seven kinds of different coarse grained soil by use of the method of standpipe,the relationship between the rising height of capillary water and time was obtained,and the influencing factors and rules were analyzed.The data of the steady rising height of capillary water were obtained,and the regression equation of coarse grained soil on steady height and physical indexes(effective grain d 10 and porosity n) was found.Compared with Hazen’s and other expressions that could estimate the steady height of capillary water of coarse grained soil,the proposed method is satisfactory and the defects of the latter were pointed out.     

铁磁形状记忆合金研究进展与展望（Ⅱ）：本构模型

阐述了铁磁形状记忆合金（Ferromagnetic Shape Memory Alloy,简写为FSMA）本构模型研究的重要性。以时间为顺序,重点介绍了FSMA本构模型研究的发展历程和研究现状。仔细分析了各种FSMA本构模型在理论基础、适用范围、精度以及复杂程度等方面的特点,讨论了各种理论应用于FSMA本构模型的局限性,指出了它们在面向应用时存在的问题。研究表明,由于FSMA兼具磁致形状记忆效应、热弹性形状记忆效应等多种独特性能,使对其本构模型的研究存在一定困难,进一步的研究还有待开展。最后指出,对既能揭示FSMA微观机理又能预测其宏观热磁力学行为的本构模型、描述FSMA所有特性的统一模型、面向应用的FSMA简化本构模型等问题,尚有待深入研究。     

中国冰川系统对气候变化响应的敏感性分析

Data of 44 glacier systems in China used in this paper were obtained from Chinese Glacier Inventories and the meteorological data were got from Meteorological Atlas of Plateau of west China. Based on the statistical analysis and functional model simulation results of the 44 glacier systems in China, the glacier systems were divided into extremely-sensitive glacier system, semi-sensitive glacier system, extremely-steady glacier system and semi-steady glacier system in terms of glacier system＇s level of water-energy exchange, rising gradient of the equilibrium line altitudes and retreating rate of area to climate warming, their median size and vertical span distribution, and their runoff characteristics to climate warming. Furthermore the functional model of glacier system to climate warming was applied in this paper to predict the average variation trends of the 4 types of glacier systems, which indicate that different sensitivity types of glacier systems respond to the climate warming differently.     

新时期吉林省参与图们江区域合作研究

吉林省参与图们江地区合作正面临着新一轮全球产业分工体系的调整、区域经济合作进程的加速、东北老工业基地振兴的深入、“长吉图”开放带动先导区的提出等新的发展背景。因此,必须重新审视吉林省与图们江地区的产业分工与合作,并对其进行重新的功能定位,提出新时期的重点发展战略,以进一步推动吉林省全面参与图们江地区的经济合作。
