『설문해자』는 중국문자학사에서 중요한 저작으로 한자의 학습과 연구에 매우 중요한 가치를 지닌다. 학술적으로 중요한 가치가 있는 이 책은 오랜 시간 동안 여러 사람의 전사와 판각과정을 거치면서 판본의 차이가 있게 되었다. 따라서 『설문해자』를 연구할 때 판본에 대한 개념이 있어야 하며 교독(校讀)을 통한 올바른 해석을 해야 한다. 특히 판본에 따른 글자의 차이(이문異文)를 비교해서 허신의 본래의 의도에 가장 부합되는 해석을 찾아야 한다. 전통적인 문헌교감의 보편적인 방법 외에도 『설문해자』 체제의 특성에서 출발한 교독 방법이 있는데, 해석체계 고찰법, 자형체계 고찰법, 어휘체계 고찰법, 문헌체계 고찰법 등의 다양한 방법이 있다. 이러한 교독 방법을 종합적으로 운용한다면 판본에 따른 이문(異文)으로 인해 발생되는 해석상의 어려움을 해결할 수 있을 것이다.
pH와 첨가제에 의한 이산화염소의 분해율 및 펄프 표백효과(2)-첨가제가 chlorate 생성량의 감소와 펄프 표백 효과에 미치는 영향

In CLO2 delignification and bleaching process, formation of chlorate corresponds to a loss of 20-36% of the original CKO2 charge. Because chlorate is inactive and harmful to environmental, it will be of benefit to find methods that can reduce the formation of chlorate during chlorine dioxide bleaching. Chlorate is mainly formed by the reaction HCIO +ClO2 $\longrightarrow$H+ + Cl_ +ClO3-2 On the other hand, AOX in chlorine dioxide bleacing is formed also due to the in-situ produced hypochlorous acid. THus both AOX and chlorate could be reduced by addition of hypochlorous acid. Some paper son the reduction of AOX by additives appeared , but systematic data on chlorate reduction as well as pulp and effluent properties are not available. THus this paper of focused on the effects on the reduction of chlorate and chlorine dioxide bleachability. The additives, fulfamic a챵, AMSO, hydrogen peroxide, oxalic acid were found to eliminate chlorine selectively in chlorine and chlorine dioxide mixture.However, when they were added to bleaching process, sulfamic acid and DMSO showed significant reduction of chlorate formation but hydrogen peroxide and oxalic aicd did not, and significant amount ofhydrogen peroxide was found resided in the bleaching effluent , In addition, sulfamic acid and DMSO decreased the bleaching end ph values while hydrogen peroxide and oxalic acid did not, which also indicated that hydrogen peroxide and oxalic acid were ineffective. The difference might be ascribed to the competitives of hypochlorous acid with lignin, chlorite (CKO2) and additives. Sulfamic acid and DMSO showed better pulpbrightness development but less alkaline extraction efficiency than hydrogen peroxide , oxalic acid and control, which means that insitu hypochlorous acid contributes to the formation of new chromophore structures that can be easily eliminated by alkaline extraction. DMSO decreased the delignification ability of chlorine dioxide due to the elimination of hypochlorous acid, but sfulfamic acid did to because the chlroinated sulfamic acid had stable bleachability. In addition, sulfamic acid, and SMSO shwed decreased color and COD of bleaching effluents, hydrogen peroxide decreased effluent color but not COD content, and oxalic acid had no statistically significant effects. No significant decreases of pulp viocosity were found except for hydrogen peroxide. Based on our results , we suggest that the effectiveness of hydrogen peroxide on the reduction of AOX in literature might be explained by other mechanisms not due to the elimination of hypochlorous acid , but to the direct decomposition of AOX by hydrogen peroxide.
