Result enunciation: Pramecium's thriving period was very different in different polluting water, and it relatived to the totle living of plankton. 结果表明:污染程度不同的水体中,草履虫的繁盛期有很大差别,且与浮游植物总生物量呈一定的相关性。
This relativity and some target of plankton's totle living could be used to appraise water quality. 利用该相关性结合浮游植物总生物量的有关生态指标来鉴定水质。
In the end, the TQM ( Totle Quality Management) system of region Road-network OD Survey was formed out through applying the relative theory of Management Economy theory. 最后,运用管理经济学中的全面质量管理理论,对区域公路网OD调查工作的全面质量管理体系进行了研究。
After Sanxia Raservoir was stored with water, its water ecological environment varied, favorable for the increase of totle fish resources. 三峡水库蓄水后,水域生态环境的变化,有利于鱼类资源总量的增长。
