查询词典 biomass

Research on individual bamboo biomass and timber physical structure indicated that the allocation of Guadua amplexifolia biomass to branch is higher than moso-bamboo evidently. Root shoot ratio is larger than other sympodial bamboo, so it can be considered as a good breakwind plant because of developed root and branch. Every modularity biomass above ground had significant positive correlation with basal diameter and total height, it can simulated with allometric model. The culm had large relative wall thickness and low moisture content, so it can be cultivated as fine timber-used bamboo.

Total biomass, root morphological index, root activity and the amount of xylem sap excaudate were measured. Results showed that under non-water stress conditions, NH4+-N supply increased the average diameter of rice roots and accumulation of shoot biomass, while NO3--N increased total root absorption area and biomass accumulation in roots.

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

The shredding of agro-residues, such as corn stalk, straw, wood sawdust and other herbaceous biomass, were investigated in this dissertation. According to the machinery mechanics of shredding, the components, shearing strength and pressive strength of the biomass were analysed in theory, which played a critical role during the shredding process. And the powder was examined by Scanning Electron Microscopy. It was founded that shearing,splitting and grinding force were appropriate for shredding biomass. The results also showed that primary shredding was the bulk shredding model, which was mainly affected by shearing and splitting force, therefore the curly knife and the straight knife were useful; while the fine shredding was the surface shredding model, affected by splitting and grinding force, and the straight knife useful.

本文以农林废弃生物质为研究对象，结合机械力破碎基础理论，从影响其破碎的化学组分和剪切强度、抗压强度等力学角度进行了理论研究，并运用扫描显微镜对破碎产物的微观结构进行了实际分析，结合二者得出如下结论：最适合生物质的施力方式为剪切力、劈碎力和磨削力；生物质粗破碎为体积破碎，主要受剪切力和劈碎力作用，刀片宜设计成弯口刀和单面直刃刀；细破碎为表面破碎，主要受剪切力和磨削力作用，刀片宜设计成双面直刃刀。

The root biomass, stem biomass and total biomass of seedling in gap center plots were ratherish higher than those of seedling in gap middle plots, but the difference was not evident.

经过一个生长季后，林窗中心样地中幼苗的根生物量、茎生物量和总生物量均略高于林窗中部样地的幼苗，但差异并不显著。

Owing to the lack of awareness of developing forestry biomass energy,the weak foundation,the perfect less system, immature exploitation technology,high development costs,market risks,the unmatch relevant policies and regulations,the lack of science and possible development planning and development strategies,they result resulting in the difficulties of developing utilization of forestry biomass energy,and forestry biomass sources being industrialized.

由于人们对发展林业生物质能源认识不足，基础薄弱，工作体系不健全，开发利用技术不成熟，开发成本高，市场风险大，相关政策及法规不配套，缺少科学、可行的发展规划及发展战略，致使林业生物质能源开发利用困难重重，林业生物质能源未能形成产业化。

Results showed that the spatial distribution type significantly affected height of individuals, aboveground biomass, belowground biomass and total biomass of C.

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的C3植物特征，相比其它类型的荒漠植物具有较高的单位叶面积P高T及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。
