查询词典 heterotrophic

The test also reveals that the removal of CODCr could not keep in pace with that of ammonia in the process of film formation , while the increasing rate of the aerobic heterotrophic bacteria is higher than that of the autotrophic nitrobacteria in the process of biological film growth.

试验还显示，挂膜过程中，CODCr 和氨氮的去除率的提高不是同步的，生物膜增长过程中，好氧异养菌的增殖速度较快，硝化菌的增殖速度较慢。

However, the sequence of their contribution is: heterotrophic nitrification 〉 autotrophic nitrification 〉 denitrification.

由于自养硝化作用在不同季节的发生，使得草甸草原土壤N2O的产生潜势也高、低起伏变化。

In the area , heterotrophic bacteria and coliform bacteria of sea water exceed serious , this showed the water be polluted.

调查海区海水中异养细菌和粪大肠杆菌超标严重，海水受到了一定的污染。

And this strain degraded H〓S without lag time. The heterotrophic bacteria's generation period was short and its growth was rapid. The result of experiment indicated when the strain Hm-6 was applying to the packed tower, the startup was more quickly and the control was more convenient than the autotrophic bacterium. Applying to deodorize the H〓S, the better removalability could be got. At the same time, comparing with the system used at home of which the biofilm directly formed with activated sludge, it runs in the neutral condition, has lower corrusivity to the equipment and was liable to handle. And this system didn't need the acclimation to become biofilm, so it can save a rather long acclimation time.

异养菌虽然不以硫化物作为能源物质，但其世代周期短、生长迅速，运行管理比自养菌更为方便，具有周期短，启动迅速等优点，接种了菌株Hm-6泥炭生物填料塔，对低浓度H〓S有较高的去除效果，且没有延迟期，与国内通常采用的直接以活性污泥挂膜的方式相比，应用该菌的脱臭系统在中性条件下运行，对设备的腐蚀性较低、运行过程较易控制，具有很好的应用前景。

The grazing of micrzooplankton,especially heterotrophic dinoflagellate was one of the important factors of diatom bloom decline.

微型浮游动物的摄食，尤其是异养的螺旋环沟藻的摄食，是水华消亡的主要原因之一。

In this paper, species diversity, community structure and feeding ecology of heterotrophic flagellate were summarized.

异养鞭毛虫物种多样性及生态学方面的系统研究将有助于对水生态系统结构、功能和过程深入了解。

The mechanism in nutrient recycling and the function in water ecosystem of heterotrophic flagellate were also discussed.

综述了异养鞭毛虫多样性、群落结构、摄食生态学以及在氮、磷循环中的作用，分析了其在生态系统中的功能。

When heterotrophic bacteria were washed out while autotrophic bacteria were accumulated, the sludge mainly was bacilliform floccule, but the sludge was petallike when the steady nitrification was set up and part nitrogen removal function was reached. The lack of organic carbon source made autotrophic bacterium become the dominates and the microbial community structures become simple.

经过成功启动并稳定运行后，单级自养脱氮系统内随着反应器内有机碳源的减少，系统中自养细菌在同异养细菌的竞争中逐渐占据优势地位，适应能力较弱或对有机碳源量要求较高的异养细菌则被大量淘汰，微生物群落结构与接种污泥相比已变得简单且较稳定，种群多样性降低。

Gracilis were applied to investigate the effect of proplastid on adaptability, in which such structure was found to be important to the competitiveness during heterotrophic growth in the dark; 2 a new procedure for differential display technology was developed and used to study the influence of plastid on nuclear gene expression, with which it was shown that the loss of plastid could cause remarkable changes in expression of certain nuclear genes.

本文主要有两点突出之处：1）应用裸藻褪色突变株与野生型的生长竞争实验探讨了原质体对于裸藻的适应意义，发现在黑暗环境和异养生长条件下原质体对于细胞的生存竞争有重要作用；2）改进了一种差异显示技术并利用该技术来研究质体的有无对基因表达的影响，证明质体丢失可导致某些核基因表达的显著变化。

We can not live without some sustenance from the biological point of view, we are heterotrophic aerobic type.

我们的生活离不开一些寄托，从生物学的角度看，我们就是异养需氧型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
