1黄土中的碳酸盐矿物特征与化学风化显示文摘从中国黄土沉积中提取古环境演化信息已取得重大进展,然而,如何有效区分黄土中原生和次生碳酸盐,进而用于追踪粉尘的来源和揭示风化成壤的强度,仍有很大困难。为了辨别黄土中不同成因的碳酸盐矿物,本文从黄土高原西部靖远和古浪剖面中选取2个典型古土壤和黄土样品(S0和L1),分为5个粒级(〈4μm,4~8μm,8~16μm,16~32μm和32~63μm),进行了热重分析(TGA)和X射线衍射测试(XRD)。结果表明:1)黄土中的碳酸盐主要由方解石和白云石组成,原生方解石和白云石在黄土中的含量比古土壤中含量高,并偏富集于粗颗粒组分;2)次生方解石在占土壤中的含量比黄土中高,并显著富集于细颗粒组分。在黄土和古土壤全样和分粒级样品中,TGA和XRD方法分别测出的Carb-B/Carb-A和(方解石+白云石)/方解石比值变化一致,有望成为反映黄土风化成壤强度的新代用指标。梁莲姬 孙有斌 Christiaan J.

4支持完整性决策的数据管理显示文摘大多数管道的运营、维护和其它设备管理部门,采用一系列各自独立的数据资源和应用程序来管理管道的完整性、维修和安全。将各个独立的数据整合成一个单一的、相互关联的数据管理系统可以提供很多重要的好处。然而,在给定管道早期投资的情况下,评价用于建立一个包含功能强大的数据采集程序在内的新系统的成本是非常困难的。采用静态的和独立的维护性数据的专用风险管理软件被作为一种快捷的、低成本的替代选择,以此来满足规章制度所规定的必须遵从的行业要求。通过开发传统数据等方法,以最小的启动成本来实现阶段性的完整性数据管理。John Beets Ed Wiegele Stuart Clouston 2005油气储运2005,24,B12:2
