查询词典 mycotrophic

On the base of mycotrophic status of different taxa, evolutionary stages and different ecophenotypes of pteridophytes, and refering to the relevant fossil materials and molecular evolution of VA mycorrhizal fungi , it could be concluded that

从不同分类群、不同进化阶段和不同生态类型的蕨类植物VA菌根营养状况以及有关的化石资料和VA菌根真菌的分子进化资料，可以初步得出

Herbs small, mycotrophic, without chlorophyll, with a slender, scaly rhizome.

小的草本，菌根营养，没有叶绿素，具一纤细，有鳞的根状茎。

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

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。
