Losses of soluble forms of organic carbon in relation to different agro-technical treatment of meadows
dissolved organic carbon meadow experiment mineral soil total organic carbon
2016/8/2
Studies were performed to determine the loss of soluble forms of organic carbon in differently used meadows on mineral soil. In a long-term experiment two variants were distinguished: a productive mea...
Labile forms of carbon and soil aggregates
ecosystem labile carbon macro-aggregates soil type
2016/8/2
Soil organic matter (SOM) plays an important role in the soil aggregation and vice versa, its incorporation into the soil aggregates is one of the mechanisms of soil organic carbon stabilization. In t...

牡丹籽油超临界二氧化碳萃取工艺（Supercritical Carbon Dioxide Extraction of Paeonia suffruticosa Andr. Seed Oil）
牡丹籽油 超临界二氧化碳萃取 中心复合设计
2009/12/28
以牡丹籽为原料，利用超临界CO2萃取提取牡丹籽油。采用单因素试验对影响牡丹籽油得率的5个影响因素（筛分粒度、CO2流量、压力、温度和时间）进行考察。以油得率为响应目标，对3个主要影响因素（筛分粒度、压力和温度）运用中心复合设计法，并经响应面法优化分析得到二次多项式回归方程预测模型，确定了超临界CO2萃取牡丹籽油的最佳条件为：筛分粒度60目，CO2流量20L/h，压力35MPa，温度45℃，时间12...
