从《分》看冰心小说创作风格的转变

《分》是冰心创作突破青春期的感伤,开始走向社会直面人生的标志。其创作风格也由早期的热烈率真而趋向宁静沉潜。而《分》的文本价值不仅在于它的现实性和阶级性,更在于其独特的儿童视角和温柔细腻的母性风范。     

司法应用写作实验教学的构想

要使课程体系既科学又实用,必须将理论课和实验课配套开设以解决理论与实践脱节的问题.应用写作学科开设实验课,不仅必要,而且可行,它既可以使学生对未来职业角色有深刻认识、理解,又能将理论知识转化为扎实的专业能力.为此,必须突破传统实验教学中"重理轻文"的模式,强调文科类职业院校同样必须重视实验教学.本文从司法应用写作入手对实验教学的内容和形式进行了有益探索.     

侵权债权在破产程序中的优先受偿顺位建构——基于“给最少受惠者最大利益”的考量

破产法的公平理念以及侵权债权的非自愿属性,决定侵权债权具有从现行破产法所规定的普通破产债权中分立出来,并优先于一般交易债权受偿的正当性。基于侵权债权类型化以及罗尔斯的公平的正义理念——给最少受惠者最大利益,侵权债权在区分人身侵权债权和财产侵权债权的基础上,应做以下受偿顺位安排:破产费用和公益债务之外,人身侵权债权——工资债权和社会保险费用——劳动补偿金债权——财产侵权债权——国家税收——一般交易债权。人身侵权债权甚至有可能优先于担保债权,如果担保债权的设立发生于人身侵权债权产生之后。社会强制责任保险费用债权视其保障范围可以先于人身侵权债权或财产侵权债权。     

公外精读课教学要加强写作能力的培养

从目前高校学生英语状况来分析,可发现公外精读课教学中存在的问题。精度课教师不仅要重视词、句的讲解,还应认识到写作教学的重要性,要把写作教学引入精读课的教学中,使写作教学以精读课教学为基础,通过多种方式的写作练习提高学生的写作技能,进而提高英语综合运用的能力。     

应用写作教学应注重课堂教学与现实写作训练相结合

应用写作是一门综合性和应用性都很强的基础课和能力课,在应用写作教学中只有将理论学习与写作实践结合起来,才能真正提高学生的写作能力。因而,教师要因地制宜地采取不同的写作训练方式,尤其要注重现实写作训练,使学生将所学的理论运用于写作实践,完成从理论到实践的升华。     

Experimental Research on Class Identification with a New Type of Erasable Gel Pens

A new type of erasable gel pen ink is becoming increasingly popular because of the modifiable characteristics for writing on documents. This study attempts to distinguish 12 types of blue and black erasable gel pens produced by mainstream stationery manufacturers using infrared (IR) visual analysis, Fourier transform infrared (FTIR) analysis, fluorescence analysis, and microspectrophotometry. The results demonstrate that IR visual, FTIR, and fluorescence analysis can be used to help distinguish each type of erasable gel ink. While microspectrophotometry can be used to effectively differentiate the blue gel inks in this study, there are limitations with respect to distinguishing black erasable gel pens. When these four optical analyses methods were used in combination, the gel inks could be accurately distinguished.     

Visualising the past – An evaluation of processes and sequences for fingermark recovery from old documents

This study aimed to collect data on the effectiveness of most of the fingermark visualisation reagents currently used on porous surfaces on fingermarks aged for up to 90?years, significantly extending the timescales for which such information exists. A limited subset of the variables associated with processing of old fingermarks was explored, with a focus on the use of 1,8 diazafluoren-9-one (DFO), 1,2-indandione, ninhydrin, and physical developer. These techniques were used in sequence on batches of cheques between 11 and 32?years old, and on documents dating from the 1920s and 1940s. The potential for applying a physical developer enhancement process (blue toning) as the final step in the sequence was also explored. The benefits of using processing sequences on porous items were clearly demonstrated, with all processes in the sequence adding value in terms of additional marks found on the cheques up to 32?years old. In addition, physical developer was found to be capable of developing fingermarks up to 90?years old, whereas the amino acid reagents appear less effective on documents of 70?years and older. An experimental physical developer formulation with reduced environmental impact was found to be as effective as the existing process in these experiments. Blue toning was found to visualise an additional 10–25% of marks, and its wider use after silver-based deposition processes is recommended based on the evidence from this study.     

芽孢杆菌CY1-3株碱性纤维素酶基因celC的克隆及其在大肠杆菌中的表达

芽孢杆菌CY1-3株基因组DNA经Sau3AⅠ部分消化后回收2~7 kb片段,构建了部分文库。通过刚果红染色鉴定,筛选出6个纤维素酶基因的阳性克隆子,经酶切鉴定为同一克隆子,命名为pGJc-1。经测序分析,该片段包含一个由1 593个核苷酸组成的开放阅读框(ORF),命名为celC。经推导,celC基因编码由一531个氨基酸残基组成的CelC蛋白。氨基酸序列分析表明,CelC蛋白的氨基酸序列与多种细菌的-β1,4-内切葡聚糖酶具有很高的同源性。粗酶液的SDS-PAGE分析表明,celC基因在大肠杆菌中所表达的CelC蛋白具有纤维素酶活力,其分子质量约为58 ku。     

鸡传染性支气管炎病毒中国分离株S1基因的序列分析

采用RTPCR方法扩增了12株鸡传染性支气管炎病毒中国分离株的全长S1基因,并进行了序列分析。通过与GenBank中登录的其他IBV参考毒株S1基因序列比较,进行了系统进化分析。结果表明,12株分离毒株属于同一个进化群的2个不同进化亚群。其中11株分离株与国内一些分离株亲缘关系最近,属于同一进化亚群,而广西分离株GX041则与欧洲毒株4/91亲缘关系较近,属于另一亚群。这些结果说明,中国各地的流行毒株变异较大,实际免疫中要根据流行毒株的特性选择合适的疫苗株来进行。
