The growth and biomass of understory plants in different site indexes and forest age existobvious difference.

不同地位指数不同林龄杉木林下植物生长和生物量存在明显差异。

Totally, these results indicated that tailing pile could be the new source for finding new heavy-metal-tolerant microorganisms. Two morphologically distinct types of colonies investigated in this study may include more than 4 undescribed bacterial species.

同时还初步发现几个有进化生态学意义的现象：(1)矿渣极强的重金属选择作用和环境隔离条件可能导致新物种在短期内形成；(2)自然选择可能在物种以上层次发挥作用；(3)不同环境因子对微生物生物量、抗性细菌比例、物种和遗传多样性等生物指征的作用不同；(4)不同的生物特征对环境因子修饰作用的敏感程度也不一样。

For year round unfenced grazing land,the total above ground biomass,overall vegetation coverage,and average plant height were all lower than for fenced land.

在全年放牧草地中，地上总生物量、植被总覆盖度、植被平均高度等指标均低于围栏内的草地。

Cougars that were displaced from their kills by bears lost an average of 0.64 kg/day of ungulate biomass, or 17-26% of their daily energy requirements.

美洲狮因被棕熊从他们的猎物边赶走而失去了平均0.64kg/天的有蹄类生物量，相当于其每日所需的17~26%。

The total mass of living matter within a given unit of environmental area.

生物量：在给定单位环境面积中生命物质的总量 2。

Software sensors, which can provide on-line estimations of unmeasurable process variables from available sensors, are very useful and promising tools in biochemical industry.

然而，目前缺乏可靠的生物量在线测量方法，使及时、迅速的控制与优化难以实现。

The analysis results for community species component and plant diversity showed that exclusion did change the species component and increase plant diversity remarkably, while the indicateor life-form structure, palatability analysis indicated that community for old exclusion is becoming perennity and unpalatability, whereas community for comparative exclusion is under stable non-equilibrium condition, in the view of vegetation coverage, mean height, biomass, palatability of plant composition, community for old exclusion has lower than new, comparative exclusion which proves partly that long-term exclusion can not increase grazing values for semi-arid rangeland.

对3种封育措施群落组成和生物多样性的分析结果表明，封育改变了群落的组成成分并增加了生物多样性，同时对群落植物的生活型、饲用价值分析计算结果则显示，老封育的群落植物逐渐向多年生发展，放牧价值开始降低，而对照区则明显处于一种非平衡的稳定状态。从3种措施植被的盖度、高度、生物量和饲用价值来看，老封育区均低于新封育区和对照区，表明长期封育不利于促进并提高草场的放牧利用价值。

The forest area in the Delta almost kept unvaried, and the forest biomass was increasing year after year, with an annual increment of about 1.2%.

随着珠江三角洲区域中、幼林不断发育成熟，区域森林的生物量将不断增加，其环境效应也将不断增强。

It indicated that vegetative growth is of very important value during the process of biomass accumulation.

在獐毛种群的生物量积累过程中，营养生长起着极其重要的作用。

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。
