Through 2 experiments in Dingxi, China, and 3 experiments in New South Wales, Australia, the research was focused on aggregation characteristic of Huangmian soil and the effects of rotation and tillage types on topsoil structure properties and organic carbon accumulation.
为此,本文通过在黄土高原雨养农业区的2个定位试验以及澳大利亚新南威尔士州3个长期定位试验,研究了黄绵土表层土壤的团聚特征以及耕作方式和轮作对农田表层土壤结构性能和有机碳累积的影响,得出以下主要结论:1.长期耕种对黄绵土表层土壤结构和有机碳含量的影响1)从整体来说,黄绵土土壤结构稳定性很差,很容易被水所分散。

当个体向大气层里排放碳时，会产生微小的社会成本，而当这些微小的成本累积起来，就造成了全球气候的加速暖化和伴随而来更严重的社会问题。
When we emit carbon into the atmosphere, we impose a tiny cost on society as a whole in the form of more rapid global warming and a greater intensity of the accompanying social ills.
所罗门说，“但至于人类在地球上的长期碳足迹，还得看累积碳排放量。”
But it's the "cumulative carbon that will determine the long-term human footprint on this planet."
图6碳烟累积量与压降增量的关系，随着碳烟的增加，压降明显增加，呈线性关系。
Figure 6 is the relation between soot cumulant and pressure drop increment, as soot increases, pressure drop increases obviously, in linear relation.
