中文摘要：

冷散开方法被用来分开并且确定三减少的无机的硫种进酸在黄和华东海的沉积的不稳定的硫化物(AVS ) ，黄铁矿和元素硫(ES ) 。结果证明直到 AVS 的 25.02 mol/g，黄铁矿的 113.1 mol/g 和 ES 的 44.4 mol/g 在黄海和华东海的沉积被观察。黄铁矿是在沉积的占优势的硫化物矿物质，当 AVS 的集中至多是相当低的时在学习区域的车站。有机物的数量和反应是为硫化物形成的主要有限因素，当铁限制和硫酸盐限制没在黄海和华东海的沉积被观察时。三减少的无机的硫种的不规则的侧面也反映了沉积作文和沉积率的全面影响。

英文摘要：

Cold diffusion methods are used to separate and quantify the three reduced inorganic sulfur species into acid volatile sulfide （AVS）, pyrite-S and element sulfur （ES） in the sediments of the Yellow and East China Seas. The results show that up to 25.02 pmol/g of AVS, 113.1 pmol/g of pyrite-S and 44.4 pmol/g of ES are observed in the sediments of the Yellow Sea and East China Sea. Pyrite-S is the predominant sulfide mineral in the sediments, while the concentration of AVS is quite low at most stations in the study area. The amounts and reactivity of organic matter are the primary limited factor for the sulfide formation, while an iron limitation and a sulfate limitation are not observed in the sediments of the Yellow Sea and East China Sea. The irregular profiles of the three reduced inorganic sulfur sediment composition and sedimentation rates. species also reflected the comprehensive influence of
