台湾当局推行国际公关的基本状况及其对海峡两岸关系的影响

1987年以来,台湾的公关事业进入新的迅速发展时期,特别是政治公关得到重视,大量运用,发展出一批具有拓展国际公关业务的专业公司,走上专业化的道路。也就在这一时期,台湾当局谋求制造“两个中国”、“一中一台”的企图日益凸显。台湾当局利用所处的特殊政治、经济地位和当前国际环境,利用台湾刚发展起来的公关技术手段,在国际上有计划,有步骤地开展公共关系活动,为其所谓的“拓展国际

遥感-岩石力学(III)——交汇断层粘滑的热红外辐射与声发射规律及其构造地震前兆意义

以构造地震孕震机制之三即交汇断层粘滑发震为模拟对象,利用双轴加载实验系统和红外热像仪对自然界经常出现的断层组合模式——不同交汇角度的组合断层的物理模型进行了室内加载实验,利用红外热像仪和声发射仪分别测定了加载过程中试样表面的红外辐射及断层活动的声发射时间序列。结果表明:(1) 声发射及红外辐射的时间序列特征受加载过程中试样的力学行为所控制,并表现出阶段性变化特点;(2) 声发射与红外辐射特征与断层几何结构有密切关系,当主应力与主断层成45°角时,红外辐射异常区主要沿主断层发育;(3) 垂直交汇的断层与斜交断层的声发射及红外辐射特征有明显差异,交汇角度(1°～90°)越大,交汇点处的红外辐射异常越明显

针对金川二矿区大体积充填体稳定性问题,简要论述近年来地表岩移和井下地压显现特征,并开展大体积充填体的变形机制研究。制定针对大体积充填体变形的监测方案:采用自制的变形监测装置对1 150~1 200 M水平50 M高充填体的相对变形进行监测,采用水准仪对大体积充填体和围岩体的下沉变形进行量测。监测结果表明,大体积充填体综合下沉变形速率为16.00~51.44 MM/月,最大累计下沉量达515 MM,大体积充填体自身相对变形速率为1.953~28.585 MM/月,最大累计相对变形为285.85 MM。进一步分析大体积充填体综合变形、自身相对变形和围岩体变形的发展趋势。研究成果对于深刻认识二矿区大体积充填体的稳定性、围岩体的变形等提供了重要的依据。The characteristics of surface subsidence and ground pressure in recent years in No.2 mine area,Jinchuan were briefly described and the mechanism of deformation was carefully analyzed.A monitoring scheme was implemented based on the results of deformation analysis.A device was made to monitor the relative deformation of bulky backfill of 50 m in height at the altitude level of 1 150 to and 1 200 m.Bubble level was used to monitor the vertical displacement of the bulky backfill and the surrounding rock.The monitoring results shows that the rate of total deformations of measurement points is 16.00 – 51.44 mm/month and that the maximum accumulated deformations is 515 mm.The rate of relative deformations at measurement points is1.953 – 28.585 mm/month, and the maximum accumulated relative deformations is 285.85 mm.The development trends of the total deformation,the relative deformation and the deformation of surrounding rock are also studied
