Shuitu Baochi Xuebao, 2017 通过室内模拟降雨试验，研究秸秆覆盖对西南岩溶区坡耕地产流产沙的影响。试验处理按照2个雨强（63，100 mm/h）和5个秸秆覆盖度水平（0，20%，50%，80%和100%）下进行。结果表明：在中雨强(63 mm/h)条件下，秸秆覆盖减少了地表径流的径流系数和径流强度，增加了壤中流径流系数和径流强度，在较大秸秆覆盖度下（50%，80%和100%），秸秆覆盖能有效减少土壤流失量；但在大雨强（100 mm/h）条件下，秸秆覆盖导致地表径流增加并同时显著减少了壤中流，地表径流的增加同时导致土壤流失量的增加。

Simulation Study of the Emission of Polycyclic Aromatic Hydrocarbons and Sugar Alcohols from Biomass Burning [PDF]
, 2015 选择水稻、小麦、玉米及棉花秸秆与马尾松枝,采集模拟燃烧时排放的PM2.5,分析PM2.5中多环芳烃(PAHS)和糖醇类化合物的含量,获得PM2.5及负载的两类化合物的排放因子;采用500 W汞灯直接照射收集了PM2.5的尘膜,获得了中、高环PAHS及左旋葡聚糖的光解动力学.结果表明,PM2.5的排放因子介于(2.26±0.60)g·kg-1(马尾松枝)~(14.33±5.26)g·kg-1(玉米秸秆)之间;19种PAHS的排放因子介于(0.82±0.21)Mg·kg-1(马尾松枝)~(11.14±5 ...

Variation characteristics of substrate and flora metabolism associated with co-fermentation of coal and corn straw [PDF]
Adding corn straw to the anaerobic fermentation system of coal can significantly increase the gas production of coal-to-biomethane. However, the changes in substrate and microbial metabolism accompanying this combined fermentation are rarely studied. The
