1·Although biomass fuel has the potential to be virtually carbon neutral, the demand for cooking wood is driving deforestation in some parts of the world.
尽管生物质燃料实际上有碳中立的潜力，但在世界上的某些地区，烹饪用木材的需求却推波助澜了滥砍滥伐。
2·Biochar is a type of charcoal produced by heating crop wastes, wood or other biomass in a simple kiln designed to limit the presence of oxygen.
生物炭是农作物废料、木材或其它生物质在简易窑(为限制氧存量而设计的窑)内经过加热而制成的一种炭。
3·But the carbon balance for biomass crops depends on the whole lifecycle.
但是，生物质农作物的碳平衡必需依赖整个生命循环。
4·Atmospheric brown clouds are made up mostly of soot - suspended carbon particles - produced by people burning biomass and fossil fuels.
大气棕色云主要是由人们燃烧生物质和化石燃料产生的炭黑(悬浮的碳颗粒)组成的。
5·The modified organism ferments sugars in the biomass to produce isoprene, in such a way that it bubbles out as a gas.
这些改良的大肠杆菌发酵生物质中所含的糖类以生合成异戊二烯，并以气体形式释放出来。
1·In fruit mature period, muskmelon had higher biomass in organic production system, but there was no significant difference on market yield in both systems.
果实成熟期，甜瓜在有机生产体系中生物量较高，但两种体系的市场产量差异不显著。
2·That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels.
这一点很重要，因为理论表明，当目标鱼种的生物量为其原始水平的50%左右时，渔场才能达到可收获的最大可持续产量。
3·The biomass of Keteleeria has been investigated and analyzed.
对油杉种群的生物量进行了测定和研究。
4·Electricity can be generated by nuclear fission, hydropower, biomass, wind and solar energy; and cars and lorries can run on electricity or biofuels.
电能可以靠核裂变、水力发电、生物量、风和太阳能产生；轿车和卡车可以通过电或生物燃料运作。
5·They have takenover and now represent 90 percent of the biomass in the Illinois River.
它们已经成了伊利诺斯河的主人，如今占那里90%的生物量。
