根据Emissions are caused by all sorts of human activities,such as burning fossil fuels (coal,oil and gas) to make energy,cutting down forests and some types of farming.(排放是由各种人类活动造成的,例如燃烧化石燃料--煤、石油和天然气,来制造能源、砍伐森林和某些类型的农业。)可知,...
Black carbon (BC) is the carbonaceous component of particulate matter formed by incomplete combustion offossil fuelsand biomass. Complete combustion would turn all carbon into CO2. In practice, combustion is never complete, and CO2, CO,volatile organic compounds, OC (organic carbon) and BC are al...
Professor John Beddington, who has warned that relying on the cutting down and burning of trees as a replacement for the use of fossil fuels could rebou... EG Ellis 被引量: 0发表: 2016年 Are Climate Claims for Burning Renewable Trees a Smokescreen? | The Tyee The answer surprised us too...
buildings need to be provided with artificial sunlight the whole year.But compared to traditional farms that take up a lot of space,vertical farming has a low carbon footprint.It can do without fossil fuels because it relies on energy from the sun.Critics are not sure whether v...
800 degrees.That's hot enough to begin manufacturing cement (水泥) and other industrial products—processes that typically rely on burning fossil fuels—and to potentially cut up to 10 percent of global greenhouse gas emissions.(由总部位于帕萨迪纳的Heliogen公司制造,每个16平方英尺...
题目Despite modem society's heavy dependence on fossil fuels for energy, most people are aware that the supply of these fuels is finite (有限的). As oil, in particular, becomes more costly and difficult to find, researchers are looking at alternative energy sources, includ...
There has been worldwide interest in finding solutions to the problems of fossil fuel shortage, air pollution, and climate change. Moreover, of concern is the kinetics of reactions, which can involve hundreds of reactants and form an enormous number of intermediate species. For these reasons, ...
The primary sources of CO are the combustion of fossil fuels, biomass burning, and the atmospheric oxidation of methane and other hydrocarbons. Whereas fossil fuel combustion is the primary source of CO in northern mid-latitudes, the oxidation of isoprene and biomass burning play an essential role...
As chemical and physical burning processes produce several compounds not attributable to other sources (e.g., fossil fuels), the detection of such specific markers is essential to evaluate the contribution of biomass burning to airborne particulate matter. A number of relevant mostly laboratory-based...
