结果表明：土壤释放的含硫气体是微生物分解含硫氨基酸、硫酸酯、还原硫酸盐的产物。
The results show that these sulfur gases emitted from soils were identified as products of microbial decomposition of sulfur-containing amino acids, diethyl sulfate and reduction of sulfate.
孢粉种属突变以及还原硫含量变化对水体深度比较敏感，是划分深水环境层序边界以及体系域的良好指标。
The abrupt changes in spore-pollen species and in the content of reduction sulfur are sensitive to water depth, and can be used as indicators for sequence boundaries and system tracts.
