SHORT COMMUNICATION COMMENTS ON THE RESIDUAL BILINEARIZATION METHOD

Through theoretical analysis and computer simulation,this short communication comments on theresidual bilinearization(RBL)method and compares it with non-bilinear rank annihilation(NBRA)forthe treatment of second-order calibration with non-bilinear data.It is found that these two methods aremathematically equivalent but have different noise propagation properties.The second-order advantage,namely quantitation in the presence of unknown interferences,can be carried over to non-bilinear dataonly if there exists a net analyte rank(NAR)for the analyte of interest.     

警惕计算机“病毒”传染蔓延

所谓计算机病毒是指可以制造故障的一段计算机程序或一组计算机指令。它被计算机编制人员偷偷地塞进一个标准化的计算机程序或者计算机操作系统,尔后,该病毒会依照指令不断地进行自我复制。有些病毒能控制计算机磁盘系统,再去感染其它程序,     

衡山构造蚀变岩型金矿特征及其找矿方向

衡山南岳岩体北侧,地质构造复杂,岩浆活动频繁,金矿成矿地质条件有利,已发现一个具有远景的金矿带,其中石子坳矿区为构造蚀变岩型金矿。本文简要地介绍了区域和矿区地质特征,总结出花岗闪长斑岩,硅化带和As元素化探异常等3条找矿标志,建议在该区开展大比例尺化探测量和地质填图,普查北西向硅化断裂破碎带,并对石子坳含金破碎带进行深部验证,寻找隐伏金矿床。
