Carbon nanotubes with larger inner diameter were synthesized by the chemical vapor deposition of carbon monoxide (CO) on iron catalyst using H2S as promoting agent. It is found that the structure and morphology of carbon nanotubes can be tailored, to some degree, by varying the experimental conditions such as precursor components and process parameters. The results show that the presence of H2S may play key role for growing Y-branched carbon nanotubes. The products were characterized by SEM, TEM, and Raman spectroscopy, respectively. Furthermore, the obtained carbon nanotubes were explored as electrode materials for supercapacitor.

This paper deals with the metallogenic model of the sandstone type uranium deposit in the northeastern Ordos Basin from aspects of uranium source, migration and deposition. A superposition metallogenic model has been established due to complex uranium mineralization processes with superposition of oil-gas reduction and thermal reformation.

中国发现的最古老铀矿床(点)集中分布在华北地台东部的鞍本地区及辽东地区其他铀矿化点、华北地台中部的中条山地区和华北地台西部的龙首山地区。通过多年来对这些地区所积累的47件晶质铀矿U-Pb同位素数据的整理处理,指出中国最古老铀矿床(矿点)尽管其成矿地域、成矿类型、成矿地质背景不同,但成矿年龄基本相同,在(1800±100)Ma左右成矿,铀成矿作用发生在早前寒武纪末吕梁造山期,而矿床可能主要在燕山运动期受到叠加改造。对华北地台东部诸省200多件方铅矿的铅同位素数据进行铅同位素数据处理:利用H-H模式分别计算了这些矿石铅源区的μ值及Th/U值,并统计了各省区μ值及Th/U值的均方差S和变异系数X;利用Pb构造模式获取不同地区铅的物质来源。文中还报道了特高放射性成因矿石铅的存在地域。矿石铅同位素示踪表明,我国辽东地区应该是很好的潜在铀成矿省。

介绍了某火电厂原水预处理系统在实现闭式循环运行过程中平流沉淀池出现出水浊度上升的问题,经分析发现其主要原因是污泥沉淀池排水泵至平流沉淀池进口位置设置不合理、进水水质不良、加药量不合理、排污量不足等问题造成的。采用回收水位置改造,排污量、加药量调整等方法,使得沉淀池出水浊度维持在0.2~0.4 NTU,每年节约水800 kt,实现了预处理系统的闭式循环运行。

本文提出用铀矿石样品U-Ra平衡系数修正样品的铀含量，再进行U-Pb等时线拟合，从而获得产铀盆地中地浸砂岩型铀矿的成矿年龄。通过对中国北方主要产铀盆地砂岩型铀矿成矿年代学研究，发现砂岩型铀矿的成矿作用具有“幕式”及多阶段性特征。不同构造单元的盆地铀成矿时代有差异，表明了铀的成矿作用与盆地构造抬升的演化历史及古气候关系密切。
