照相锌版印刷术和照相石印术的发明及传华时间新考

与国内印刷史界目前通行的观点不同,照相锌版印刷术和照相石印术皆由英国人詹姆斯和斯科特在1859年发明,并且早在1876年就通过《测地绘图》一书中所附的《照印法》首次被介绍到我国.     

被误用的纸币印刷术

大家在中学历史课本上都学过中国是纸币的故乡，产生于北宋时期的交子是世界上最早的纸币，比欧洲早600多年。然而，当1840年英国的坚船利炮轰开中国国门的时候，英格兰银行的纸币已经通行于世界，而中国却还在使用白银和铜钱作为货币。     

The research and progress of micro-fabrication technologies of two-dimensional photonic crystal

The novel material of photonic crystal makes it possible to control a photon, and the photonic integration will have breakthrough progress due to the application of photonic crystal. It is based on the photonic crystal device that the photonic crystal integration could be realized. Therefore, we should first investigate photonic crystal devices based on the active and the passive semiconductor materials, which may have great potential application in photonic integration. The most practical and important method to fabricate two-dimensional photonic crystal is the micro-manufacture method. In this paper, we summarize and evaluate the fabrication methods of two-dimensional photonic crystal in near-infrared region, including electron beam lithography, selection of mask, dry etching, and some works of ours. This will be beneficial to the study of the photonic crystal in China.     

图案化自组装有机单分子薄膜

目的图案化自组装有机单分子薄膜,开辟低成本、高效率制备有机单分子薄膜图案的新途径。方法采用光刻蚀的方法制备聚二甲基硅氧烷(PDMS)模子,通过模板诱导组装,将有机分子十六烷基硫醇(HDT)、1,10-癸二硫醇(DDT)和4-十二烷基硫醇邻苯二酚(MBD)选择性沉积在金表面。结果得到规则有序的有机单分子层图案。结论利用有机分子端基官能团功能化金表面,这种被功能化的金试样是形成纳米颗粒图案和制备有机分子器件的基础。     

Study on the Thermal and Mechanical Properties of the UV-cured SL5510 Stereolithography Material

In recent years, Vantico A ＆T US Incorporation has developed a type of the hightest accuracy photosensitive resin： SL5510 stereolithography material （briefly named SL5510） to use in the stereolithography apparatus（SLA）. In this paper, the thermal and mechanical properties were investigated for the fabricated specimens of SL5510 in the different UV post-cure time. This may instruct us to employ better the fabricated parts of SL5510.     

中国为什么难出大科学家——对我们科学研究缺陷的思考

纵观世界，中华民族历史悠久、灿烂，有着五千多年文明的发展。造纸、印刷术、指南针和火药都是由中国人发明创造的，传入世界各地对人类文明做出了重大贡献。     

传播的革命：印刷术对德国宗教改革的影响——由爱森斯坦的观点引发的思考

上世纪80年代以来,随着爱森斯坦专著《作为一种变革动力的印刷出版：欧洲近代早期的传播与文化变迁》的问世,学界对其给予印刷术对宗教改革乃至近代社会转型的巨大肯定就一直争议不断。爱森斯坦的观点虽然具有局限性,但对于我们思考印刷术对德国宗教改革的影响也非常具有启发性。     

Preparation of porous nanocrystalline TiO2 electrode by screen-printing technique

Different paste has been used for preparing porous TiO2 thin film by screen-printing technique, the main component of it comes from commercial TiO2 P25 power. The dye-sensitized solar cell based on this TiO2 thin film without further chemical treatments exhibits high overall conversion efficiency of 5.81%―6.70%, even with low TiO2 content and thin film thickness. The experimental repeatability is nice and the properties of the films are uniform.     

印刷术的起源地：韩国还是中国？

１９６６年韩国庆州发现印本《无垢净光大陀罗尼经》后，至今已三十年。然对其刊行年代仍众说纷纭，对刊行地点也有两种不同见解──韩国刊行说和中国刊行说。持韩国刊行说的学者提出韩国印刷起源最早，近来更要求世界公认此说。本文对此经的深入而较为系统的研究，考得其译于７０１年，７０２年刻印于中国洛阳，证明韩国刊行说不能成立，同时为印刷术起源于中国的定论提供了新的证据。     

地方志·印刷术与国情

上个世纪60年代一个寂寞的夏天,未名湖畔人影寥寥,聒噪的蝉声在山岗的绿荫里此起彼伏,而同窗多年的学友也各奔前程了。但是,我却仍然留在这寂寞的校园等候着即将奔赴的异地。大约是积习难改罢,依然是每日从人去楼空的宿舍沿着野草蔓长的湖畔去那宫殿式的图书馆。暑期的图书馆很少有人光
