고문 교육에 있어서 허사는 가장 중요한 부분이자, 가장 어려운 부분이다. 본문은 인민교육출 판사의 『普通高中課程標準實驗教科書(必修)』에 수록된 고문을 대상으로, 현재 고등학교의 고 문 교육과 평가 영역에서 다루는 18종의 주요 허사의 의미 분포와 주석 양상에 대해 전면적인 통계 분석을 진행하고, 그 분석 결과를 바탕으로 고문 허사 교수법에 대한 몇 가지 의견을 제시하 였다. 이를 통해 고문의 허사 교육이 과학적이고 체계적인 방향으로 발전하기를 기대해 본다. Function words are the key and difficult points in classical Chinese teaching. In this paper, the author takes the classical chinese materials from the standard experimental textbook (compulsory) of senior high school printed by People's Education Press as the research object. A comprehensive statistics on and analysis of 18 key function words distributed and noted in the textbook during teaching and tests were taken. Based on the results, some practical suggestions on the teaching of classical Chinese function words are put forward in order to promote the scientific and systematic development of the teaching of classical Chinese functional words.

The effects of aging for improving wastewater sludge electro-dewatering performances
Hang Lv,Daoguang Liu,Siqi Xing,Dandan Wu,Fang Wang,Jiakuan Yang,Xu Wu,Wenbiao Zhang,Xiaohu Da 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.80 No.-
The effects of sludge aging on improving sludge electro-dewatering (SED) performance were studied,with the sludge properties variation during aging process investigated. Sludge electro-dewateringperformances were explored by constant voltage method (25 V) on various samples. The organic matterin the extracellular polymeric substances (EPS) was gradually consumed and decomposed during sludgeaging process. Under identical electro-dewatering conditions, dewaterability and time-space yield ofaged sludge achieved 49.33% solid content and 223.46 kg m 2 h 1 respectively. Such results indicate thebeneficial effects of sludge aging process in terms of SED performances, which needs further explorationinto fundamental mechanisms.

BACKGROUND: Nowadays, biological tissue engineering is a growing field of research. Biocompatibility is a key indicator for measuring tissue engineering biomaterials, which is of great significance for the replacement and repair of damaged tissues. METHODS: In this study, using gelatin, carboxymethyl chitosan, and sodium alginate, a tissue engineering material scaffold that can carry cells was successfully prepared. The material was characterized by Fourier transforms infrared spectroscopy. In addition, the prepared scaffolds have physicochemical properties, such as swelling ratio, biodegradability. we observed the biocompatibility of the hydrogel to different adult stem cells (BMSCs and ADSCs) in vivo and in vitro. Adult stem cells were planted on gelatin-carboxymethyl chitosan-sodium alginate (Gel/SA/CMCS) hydrogels for 7 days in vitro, and the survival of stem cells in vitro was observed by live/died staining. Gel/SA/CMCS hydrogels loaded with stem cells were subcutaneously transplanted into nude mice for 14 days of in vivo culture observation. The survival of adult stem cells was observed by staining for stem cell surface markers (CD29, CD90) and Ki67. RESULTS: The scaffolds had a microporous structure with an appropriate pore size (about 80 lm). Live/died staining showed that adult stem cells could stably survive in Gel/SA/CMCS hydrogels for at least 7 days. After 14 days of culture in nude mice, Ki67 staining showed that the stem cells supported by Gel/SA/CMCS hydrogel still had high proliferation activity. CONCLUSION: Gel/SA/CMCSs hydrogel has a stable interpenetrating porous structure, suitable swelling performance and degradation rate, can promote and support the survival of adult stem cells in vivo and in vitro, and has good biocompatibility. Therefore, Gel/SA/CMCS hydrogel is a strong candidate for biological tissue engineering materials.
