例如，沼泽贫瘠的土壤提供的氮和磷很少，所以肉食植物比那些通过更传统的方式获得这些营养的植物更有优势。
The poor soil of bogs, for example, offers little nitrogen and phosphorus, so carnivorous plants enjoy an advantage over plants that obtain these nutrients by more conventional means.
过高的氮磷比不利于浮游植物进行光合作用。
The high rate of nitrogen and phosphorus is unfavourable to the photosynthesis of the phytoplankton.
维持培养液中适当低的氮水平，并保证足够量的磷供应即较低的氮磷比是促进塔玛亚历山大藻生长的重要原因。
Maintenance of continues low level nitrate with sufficient supply of phosphate, namely low N:P ratio, may facilitate the growth of Alexandrium tamarense.
它们的氮含量均大于磷含量，周转期氮需13年比磷需12年为慢。
The turnover periods of N and Pwere 13 and 12 years respectively.
随着负荷、污水C／N比、温度、光照时间等因素的变化，氮磷去除呈一定的变化规律。
The removal rule of N or P in series ponds is affected by the changes of loading, COD…
