Instead of burning biomass directly , it can also be gasified .

除了直接燃烧之外，生物质也可以气化。

Scientists use these changes in ocean color to estimate chlorophyll concentration and the biomass of phytoplankton in the ocean .

科学家利用海洋颜色的变化来估计叶绿素含量以及海洋浮游植物的生物量。

Biomass is a regionally available energy resource that could help reduce co2 emissions .

生物质是区域性现有能源，有助于减少二氧化碳排放。

Moreover , supply chains for biomass are still being developed , so the availability of feedstock will change .

此外，生物质的供应链仍在发展，所以给料供应的可操作性有待改进。

They multiply rapidly-some species double their biomass in as little as five hours .

他们繁殖迅速一些品种（硅藻）的生物质在短短5小时内即可翻一倍。
