清教主义对于美国人的思想影响极其巨大。最杰出的清教主义神学家爱德华兹与美国建国前后理想与价值观之父富兰克林分别代表了清教主义的两个方面:在绝对神权崇拜中赎罪和通过自己的善行与自律追求天赋的人权。木文通过对这两种典型思想的产生渊源与本质的分析,揭示了他们之间的差异以及宗教信仰上的延续性。  相似文献

Abstract

Metals cycle through the environment, and although many metals are required by biota, several have no known biological function and can be toxic. Metal concentrations [cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), palladium (Pd), vanadium (V), and zinc (Zn)] are surveyed with an eye toward soil chemistry, environmental and anthropogenic conditions, and potential remediation in 15 locations in and adjacent to Franklin County, MA. Road‐condition information was gathered, soil pH determined, and soils analyzed for soil metal content via a five‐phase sequential extraction and ICP‐AES analyses. Results indicate the majority of similarities are linked to soil pH and soil geochemistry, with only a few metals (Cr, Pb, and Zn) showing clear anthropogenic trends.  相似文献
