Experimental results showed that, in this process, the optimal pH of the shortcut nitrification was 8.0～8.5; when the pH was less than 6,the nitrification is completely inhibited; when the pH was 6～7, at the end of aeration, the Nitrobacteria become the dominant bacteria because of the dropping of the free ammonia concentration.

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。
