Even thought the students tell the illustration and the proposition correctly, only few of them know that merely one counter-example is needed to contradict the proposition. Most students are rather inclined to regard the counter-example as restrictions and exceptions just like Lakatos says when the number of counter-example is less and example more than contradict proposition of examples. As a result, they are less able to deny negative proposition.

结果发现即使拥有正确判断图例与命题间关系的学童，在面临同时有正反例图例时，只有极少数学生知道只要一个反例就可驳斥命题，大部分学生在反例较少而正例多时，会倾向如Lakatos所描述把反例视为题目的限制或是特例，而不与有较多正例支持的命题陈述来冲突，故较无法正确拒绝错误命题。

Thirdly, Lu Xun is undoubtedly "a man with eyes by which could see the subtle irony"-Not only could he see the subtleness of irony, but also the irony of himself, the nihil world as well as the nihility itself.

第三个方面即鲁迅无疑是一个"长着看得见反讽的眼睛的人"。他不仅看得见反讽，而且看得见自身的反讽，不仅虚无世界的一切，而且虚无这虚无本身。

According to the above study results, especially the steady operation of two-sludge system（2A/O+N 2SBR）, it can be proved that denitrification and excess phosphorus uptake are relatively independent and intersectant biological processes. The overlap is that denitrifying phosphorus removing bacteriawhich possesses the two bacterial metabolisms, could utilize nitrate as an electron acceptor for phosphorus uptake. The two-sludge system can not only combined biological phosphorus removal and denitrification processes to form a process in practical wastwater treatment , but also solved the main difficulties of current single-sludge systems:①the sludge age competition between phosphorus removing bacteria and nitrifier;② the substrate competition between denitrification and dephosphatation.

以上的研究结果，尤其是时间序列的双泥生物反硝化除磷脱氮系统工艺（2A/O+N 2SBR法）的稳定运行，不仅证明了生物脱氮与生物除磷是两个既相对独立又相互交叉的生理过程，其交叉点是同时拥有硝酸盐还原性和超量吸磷这两种生化特性的细菌进行的反硝化吸磷脱氮生化反应，而且双泥系统工艺克服了常规单泥生物脱氮除磷工艺的两大问题（①聚磷菌和硝化菌的SRT相互干扰；②反硝化与生物除磷竞争VFA），同时保证了脱氮和除磷效果，排水指标达到污水综合排水标准（GB8978-1996）的一级标准，具有实际工程使用价值。
