诗歌中的盛唐气象

盛唐时期的经济、社会、文化孕育了繁荣的盛唐诗歌和诗歌中独特的盛唐气象。这种气象 ,不仅从边塞诗歌作品豪迈、雄浑的风格中体现出来 ,也从山水诗歌作品清新、优美的风格中体现出来 ;不仅从天真、浪漫的诗人作品中体现出来 ,也从现实、沉潜的诗人作品中体现出来 ;不仅以诗歌的艺术形式来表现 ,也以诗人的情怀、理想、精神风貌来表现 ;不只是某个诗人的创作表现出这种气象 ,而是该时期诗人群体创作共同形成的时代气象     

杜甫诗歌的色彩艺术

杜甫善于运用色彩这种绚丽的视觉语言,很注意色调的运用,他的诗本身就是五色缤纷的世界,用形象事物特有的光彩来描述人生旅途的见闻和感慨。在杜甫诗歌中,色彩又是意境创造的重要方式,也是理想人格的有效载体。杜诗色彩的运用极富特点,有着完整的、成熟的、自成体系的用色技巧。后代诗人在用色方面大多是继承了杜甫的手法,再没有人能在体系上全面超过他。这与杜甫"语不惊人死不休"的写作追求是分不开的。     

In situ spectroscopic ellipsometry: Application to Sb coverage measurement in the monolayer range on Si (111)

In this paper, we present an analysis of antinomy deposition on silicon in the range of 0.1 to 1 monolayer by in situ spectroscopic ellipsometry. After a careful choice of viewpoint material, ellipsometric measurements are found to be sensitive to small surface perturbations, especially with antimony. In fact, less than a 0.1 monolayer of antimony on silicon at room temperature is detectable. Moreover, a linear dependence of the ellipsometric signal on Sb coverage is observed in the monolayer range. Consequently, the signal versus time variation directly gives the Sb adsorption kinetics on silicon. The saturation to one monolayer of compact antimony on silicon surface is used in order to calibrate the spectra.     

杜诗评解志疑（续）

唐诗的解释工作历来做的人很多，而且十分深入，这也是一笔丰富的文学遗产。本文就杜甫诗若干名篇名句的评解提出讨论，归综诸说，较论异同，断以己见，供阅读和研究参考。     

杜牧诗歌中数字入诗的艺术

在中国古代诗歌中,早就存在以数字入诗的现象,但杜牧却将这一手法加以充分的运用。在他现存的诗歌中,有一半以上的诗歌中用到了数字。在他的以数字入诗的诗歌中,运用数字的方式多种多样,收到了很好的艺术效果。     

鸿都门学设立的原因及其文学思想史意义

汉末两次党锢之祸加剧了经学的式微,士人普遍表现出一种疏离政权的倾向,朝廷以经学取士的方式无法正常进行,灵帝在此际设立鸿都门学即是对选举制度所作的一次改革。当时社会围绕鸿都门学的争论映照出不同的文学观念:汉灵帝及鸿都诸生皆以书法辞赋作为利禄之途,是功利主义文学观;以杨赐、阳球为代表的正直士大夫主张罢除鸿都门学,对文学持否定的态度,是功利主义文学观的极端发展;蔡邕则从反对鸿都门学的角度认识到了文学的审美娱乐功能。三者皆反映出文学独立于经学的事实,因此鸿都门学的设立在文学思想发展过程中具有转折意义。     

论杜诗中的悯农题材

唐代大诗人杜甫在其一生的诗歌创作中,有许许多多关注农耕、忧心农事的悯农之作。在这些作品中,诗人以其现实主义的创作手法,将其所处"安史之乱"前后农夫所遭受的众多天灾、兵祸之苦真实记录下来,并将自己对他们的哀悯、同情与赞许等诸多情感寄寓其中;这与其所继承的重农耕的儒家思想传统密切相关。同时,这一题材的开拓,对后世悯农诗创作产生了深远的影响,在中国古代文学史上具有重要的地位。     

论《牡丹亭》、《红楼梦》之孝亲意识与中国古代孝文化

中国古代孝文化是立足家庭教育,面向社会的,培养子女孝的意识不仅是为了父母,也是为了社会和谐。《牡丹亭》与《红楼梦》不仅在大胆张扬男女爱情上有共同点,在保留孝亲意识上也是相同的。这是对中国古代孝文化的继承,显示了汤显祖与曹雪芹这两位伟大作家的共同认识,是他们对明清官方文化突破中的保留,与20世纪初的全盘抛弃传统文化并不相同。     

Atomic force microscopy studies on phase transitions and surface morphology transformation of CMTC crystals

Atomic force microscopy (AFM) has been used to investigate the phase transitions and surface morphology transformation of cadmium mercury thiocyanate (CMTC) crystals, which are highly efficient nonlinear optical (NLO) materials for generating blue-violet light by laser frequency doubling. Amorphous aggregates at the crystalline steps become greatly contracted and much more crystalloid after the crystal was kept for one day. Elimination of dangling bonds, which lower the surface free energy at the crystal surface, and structural adjustment inside the crystal are assumed to cause this phase transition. Surface morphology transformations were also observed in CMTC crystals during and after multiple scanning by AFM tips. We have visualized the continuous translation process from two-dimensional nuclei to trigonal microcrystals with almost equal sizes during multiple scanning. In other cases, however, the surface morphology did not change at all during scanning, but became greatly altered hours after scanning. These experimental results suggest that reconstruction is a characteristic growth phenomenon on CMTC crystal surfaces. Reconstruction probably results from the formation of intervening metastable phases that have the potential to arrive at more stable stages; however, multiple scanning of AFM tips greatly affects this translation process.
