查询词典 biomass

The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time.

研究表明：生物质脱硝能力明显高于煤粉，提高再然比例及减小过量空气系数，3种燃料的脱硝率有不同程度的提高，其中秸秆脱硝率最高，稻壳中等，煤粉最低；在一定的再燃停留时间内(650 ms)，延长停留时间，脱硝率增加，超过这一停留时间，脱硝率增加缓慢。

Root dry weight and aerial biomass of Rumex bucephalopherus were relevant to SCR in growth solution under saline condi-tions.

盐渍条件下酸模的根系生长量及地上部分生长量与溶液SCR有密切联系，较高的溶液SCR制约酸模根系与地上部分的生长。

The biomass photosynthesis activity of Ruppia maritima and Potamogeton pectinatus and the proline,malondialdehyde,catalase,and chlorophyll contents in their leaf-tissues in response to salinity were studied by investigating the plants cultured with reclaimed wastewater of different salinities.

通过在不同盐度再生水中培养川蔓藻和蓖齿眼子菜，研究了它们的生物量、光合强度及其组织中的脯氨酸、丙二醛、过氧化氢酶和叶绿素的含量变化对再生水中盐度的响应。

Salicornia europaea L.; salinity tolerance ; biomass ; branching ; density ; water and salt stresses

盐角草（S.europaea L。）；耐盐性；生物量；分枝；密度；水分胁迫；盐分胁迫

Grazing reduced aboveground biomass of the communities except in the Stipa klemenzii community. In this case annual warm season plant, Salsola collina, became absolutely dominant species in the community under heavy grazing intensity.

群落地上现存量一般随放牧强度的增大而下降，但小针茅群落反之，主要与一年生植物猪毛菜的生物量迅速增加有关。

School of chemical engineering, ch ina university of mining and technology, xuzhou jiangsu 221008, china） abstract: pyrolysis gasification semicoke charateristics of two kinds of fresh b iomass were studied in order to better investigate the pyrolysis gasification me chanism of fresh biomass.

中国矿 业大学化工学院，江苏徐州221008）摘要：为了更全面地研究新鲜生物质的热解气化过程，对二种新鲜生物质不同热解气化条件下的半焦特性进行了研究。

Most herbivores feed in secondary forests because pioneer species in secondary forests do have little or no mechanical or chemical protection against herbivores and many early and late seral tree species in secondary forests produce edible fruits in large quantities. Environment and fire have some effects on secondary forest succession. In early succession, relatively more biomass is allocated to resource acquiring tissues and in later stages more is allocated towards structural materials.

大多数食草动物喜欢在次生林中取食，因为次生林中的先锋树种很少或没有机械和化学保护和林内许多树种产生大量可食用的果实；环境和火对次生林演替有一定影响；在早期的演替过程中，更多的生物量分配到资源需求旺盛的组织，在演替晚期阶段，更多的生物量则分配到结构组织中。

The metabolic energy and fodder unit of Arthraxon pricnodes per unit area reached a peak of 4.88×103 kJ*m-2 and 3891 FU*hm-2,77.5%and 80.8%higher than the lowest value. The effect of temperature on dry biomass of Setaria faberii and S. sudanense in each growing season was not significant, nor was relative humidity.

不论是单个生长季的温度，还是几个生长季温度的组合，对于狗尾草和苏丹草干重的影响都是不显著的，相对湿度也是如此。

"Biomass burning" from forest fires, vegetation clearing and fossil fuel was just as much to blame for the shrouding haze as dirty industries from Asia's great cities, the study found.

研究发现，除了亚洲大城市中一些污染环境的工业之外，森林大火、植被清除和燃料燃烧对环境同样造成了严重的污染，因而也是这片亚洲褐云形成的原因之一。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
