一种新的振幅滤波法在化磁极中的应用

本文针对低纬度地区频率域化磁极存在的问题，在频谱分析的基础上，提出了一种新的滤波方法即振幅滤波法。该方法能将低纬度地区化极磁场的频谱恢复到垂直磁化磁场的频谱，大大提高了低纬度地区化磁极的精度。     

Geochemical survey of thermal system in Northeast China and their geothermometric characters

The chemical composition of several thermal springs around Changbaishan area has been investigated. Cenozoic basaltic rocks are widely distributed in Northeast China and geothermal characteristics have been described. About one hundred hot springs exist around Changhaishan Volcano at the border between China and D.P.R.Korea with high temperature about 82~C. The pH values of the spring water range from 6.9 to 7.1 and the total flow rate is about 4.8 L/sec. The chemical composition of the thermal springs is sodium carbonate; the high-mineral contents of thermal water are believed to have medicinal properties. Bathhouses are already built along the hot springs to take the advantage of the supposed healing properties. The high quality of those hot springs is believed to be utilitized for mineral water. The chemical equilibrium temperatures were estimated at about 160℃ based on the Na-K-Ca geochemical thermometer.     

西秦岭温泉花岗岩体岩石学特征及岩浆混合标志

温泉花岗岩体由酸性端元的寄主岩石和暗色微细粒镁铁质包体群及基性岩墙群组成。无岩浆混合作用或岩浆混合作用较弱区段，寄主岩石以似斑状二长花岗岩为主．显示正常的花岗岩结构构造岩浆混合作用强烈区段。岩石的异常结构构造十分发育．矿物之间自形程度差异显著．常见包晶反应、包含结构、交代边、熔蚀边、交代蚕食的港湾状结构构造及交代缝合线、矿物镶边、斜长石异常环带和矿物残留等，多见指示岩浆混合的标志性矿物针状磷灰石。暗色微粒包体中多见寄主二长花岗岩中的捕掳晶。包体的形态、结构构造以及与寄主岩石强烈地成分交换等均是岩浆混合作用的标志。     

省厅人事部门开展“树组工干部形象”效果好

2003年7月中旬以来,历时近半年的河南省国土资源厅人事部门开展的“树组工干部形象”活动,目前已取得显著成效。人事部门广大干部“对己清正、对人公正、对内严格、对外平等”的良好品德,赢得了各方面的交口称赞。 从近半年厅人事部门开展的“树组工干部形象”活动开展情况看,有四个明显特点: 一是厅党组及各级领导普遍重视。厅里成立了以厅党组书记、厅长林景顺同志为组长的“树组工干部形象”活动领导小组,领导小组下设办公室,厅“学教”办结合河南国土资源工作的实际和特点,统筹安排,制定了比较详细的开展“树组工干部形象”集中学…     

百姓之事皆大事

日前，一位下基层督促信访的好友入室小坐。问起下面情况怎么样时．他深有感触地说：“要想为群众办成一件事，光人下去还不行，还得对老百姓有感情，真正把百姓之事当成大事办，一句话．‘得上心’”。
