您要查找的是不是:
- S ratio (belowground to aboveground biomass ratio) has been widely used for estimating root biomass. 利用根冠比(R:S)和地上生物量来估算地下生物量是目前常用的方法,但目前缺乏根冠比的数据。
- When sleam to biomass ratio (S/B) is smaller than 0.37, the H2 content rises with the increasing of the S/B, but the H2 content decreases slowly when it is larger than 0.37. 发现在水蒸气和生物质比率(S/B)小于0.;37时,氢的百分含量随S/B的增大而增加,S/B大于0
