1.
Based on the analysis, contrast and conclusion of its secondary enrichment zones,the changing regulation of depth,thickness and grade of the secondary enrichment zones in the Leimengou gold deposit were brought to light,and the forming mechanism of secondary enrichment zones was further expounded in theory.
本文从三条典型含金蚀变破碎带入手 ,通过对其次生富集带的分析、对比、归纳 ,揭示出次生富集带的深度、厚度和品位变化规律 ,并进一步从理论上阐明次生富集带的形成机理。

Bauxite ore in Songqi area,Henan province is characterized by secondary enrichment.
河南省嵩箕地区铝土矿具有明显的次生富集规律:次生富集最强的部位在潜水面附近,通常为矿体埋深40~70 m的部位;深度大于130 m的含矿地段氧化程度变低、矿石质量下降;矿石氧化富集的内因为Al2O3和SiO2的地球化学差异,外因是矿体内地下水的补给量及其排泄能力的强弱,铝土矿在次生氧化作用中不断地脱硅富铝,形成富铝土矿石;适宜的构造和地貌条件是地下水补给、排泄的有利保证,上石炭统底部靠近铝土矿层的岩溶溶洞是向矿层内补充大气降水的主要通道。
4) secondary enrichment zone
次生富集带

2.
In order to understand the enrichment mechanism of heavy metals in soil particulate organic matter(POM),four chemical species of Cu and Pb in the POM,including exchangeable,complex,organic tightly bound and mineral bound,were characterized by chemical selective extraction.
为了解土壤颗粒态有机质(POM)中重金属的富集机理,采用化学试剂选择提取方法,把POM中铜和铅分为可交换态、络合态、有机质紧结合态和矿质态等4种形态。
6) element enrichment mechanism

【诗文】：
寿宿腾光，寿香袅碧，郁葱枝上梧桐。记＊麟令旦，门挂弧蓬。今年东阁郎皆侍，怀章绶、拜捧金钟。荣华富贵，眼前谁似，堪展眉峰。秋高景物俱浓。正阶前金菊，巧对芙蓉。爱菊名寿客，寿与公同。醉蓉初莹凝脂面，酣天酒、芳脸潮红。何妨判饮，与花双醉，醉似花容。
