The time of the pedogenic process was in the last ice age, therefore this area was colder and drier in climate and lower in sea level than today. The main chemical process in the soil was oxidation, a period of the formation of oxide minerals such as limonite. With the deposition and covering of the marine facies layer in the postglacial period, the soil turned into diagenetic process. Consequently the chemical process in the soil was dominated by reduction and this process was the main development period for nodules of iron-manganese carbonate to form.

成土期处于末次冰期低海面、气候寒冷干燥期，土壤的化学过程是以氧化作用为主，是褐铁矿等氧化性矿物形成时期；冰后期海相层的沉积覆盖使土壤层进入成者阶段，土壤层的化学过程以还原作用为主，成岩过程是铁锰碳酸盆结核的主要生成期。

The redox separation conditions were investigated in detail. It was indicated that TBAPI exhibited appropriate oxidation intensity and well selectivity, thiolethers can be oxidized into sulphoxide, but it cannot oxidize thiols.

详细考察了氧化还原分离条件，实验结果表明，TBAPI具有适宜的氧化强度和良好的选择性，它能将硫醚硫氧化成亚砜，且在同条件下，对噻吩硫不起作用。
