查询词典 autotrophic

The carbon dioxide in the atmosphere is taken up by autotrophic organisms and incorporated into carbohydrates.

在大气中存在的二氧化碳被自养生物体所吸收并合成为碳水化合物。

Y structure and function, BLSS can be divided into two parts: autotrophic unit and heterotrophic unit.

LSS在结构和功能上可以分为自养单元和异养单元两部分。

Autotrophic mutants were prepared from six different stocks of a special group.

Biofilm is one of the key factors of the one-step completely autotrophic nitrogen removal process under high DO.

生物膜是高溶解氧条件下实现单级自养脱氮的一个关键因素。

This stage can be divided into three growth phases: heterotrophic, heterotrophic and autotrophic, autotrophic nutrition.

按营养方式，将该期划分成异养、异养和自养并进及完全自养三个生长阶段。

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。

After comparison of various process, a optimum process—ANIS process can be drawn; A autotrophic denitrifying process is successfully started up and stable operated; ANIS nitrous nitrifying process and autotrophic denitrifying process are joining-up in series to operate, and sound nitrogen removal effect can be achieved.

本论文广泛研究了各类C/N均小于1、甚至低至0.5以下的低、中、高氨氮浓度废水进行亚硝化处理的效果，综合比较了各种不同的处理工艺，得出了最佳工艺——ANIS工艺和运行条件；成功启动并稳定运行了自养反亚硝化系统，并将ANIS亚硝化工艺和自养反亚硝化工艺串连运行，取得了良好的脱氮效果。

In filicophytes, there was a relatively high ratio of VA mycotrophy in the eusporangiates, and there was no autotrophic in the eusporangiates; but the ratio of autotrophic was up to 71%, and the ratioes of VA mycotrophic and facultative mycotrophic were low, 15% and 14% respectively in the leptosporangiates.

用碱解离、酸性品红染色法对云南热带、亚热带自然生长和部分移栽到温室中的256种（拟蕨类植物20种，真蕨类植物236种）蕨类植物孢子体的VA菌根状况进行了调查研究，结果发现，在拟蕨类植物中，孢子体只存在兼性VA菌根营养和自养两种菌根营养类型，两种类型，两种类型所占的比例相当；在真蕨类植物中，厚囊蕨类植物VA菌根营养的比例较高（92%），且无自养类型；而在薄囊蕨类植物中，自养型占71%，VA菌根营养和兼性菌根营养所占的比例都不高，分别是15%和14%。

In the fern allies, there was no obviously evolutional trend among the mycotrophic, facultative mycotrophic and autotrophic, however, the evolutionary trend may be from the mycotrophic to facultative mycotrophic, and at last to the autotrophic which got rid of mycotrophism in the filicophytes

在拟蕨类植物中，VA菌根营养、兼性菌根营养和自养之间无明显的进化趋势；而在真蕨类植物中，则由VA菌根营养向着兼性菌根营养到最后摆脱菌根营养而行自养的方向演化

The kinetics process and temperature impact of natural groundwater denitrified by sulfur autotrophic was investigated. The results revealed that the denitrification rate of up-flow sulfur autotrophic denitrification filter followed a half-order kinetics model; and the reaction rate constant was mainly affected by the temperature. Based on the Arrhenius calculation, the activated energy was 80.38 kJ/mol.
