多样性

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。

Perception is filtered by our cultural mores.interpretation will siverge :the same sting of hesrtbreak inspires a flok singer's melancholy ballad and a rocker's deafening song.harmony is obtained through respect,while firmly grasping personal beliefs.this equation balances one's own passion and embraces individual perspectives.

文化道德观念可以提升我们对事物的理解。面理解通常都具有多样性；同样的悲伤可以创造出民族歌谣或是摇滚乐曲。相互的尊重产生和谐之美，同时兼顾个体的信仰。这样既平衡了自身的情感又包含各自的特性。
