摘要：文章从视觉心理学和创造心理学的角度阐述了肌理在艺术创作中的作用。国画、油画、版画和其它艺术创作中肌理的运用和由肌理创造出的各异的艺术效果、艺术气氛所带来的和谐、活力和生命，给人一种奇幻的美感。肌理的运用为艺术家塑造物象、表现思想开辟了一个崭新的天地。

摘要：每一种新原素的发现使科学、社会前进一步,同样一种新材料的发现和利用也会给工艺美术增加一个新品种。如雕刻工艺品种的木雕,就有红木雕刻,东阳木雕、黄阳木雕、金木雕、鸟木雕、白木雕、樟木雕、树根雕等。由素材的冲动到形式的冲动。

摘要：黑和白是色彩中对比最为强烈的两个极端色,由黑白构成的艺术画面具有独特的魅力。本文探讨了有关黑白艺术的几个问题:黑白存在的客观依据是以物象的明度来区分的;黑白反衬既对立又统一;概括黑白的方法主要是物象的明暗关系、物象的固有色和深浅度、主观创作意图;黑白灰靠对比而存在,其比例大小给人以不同的视觉印象。

摘要：Quantum confinement effect（QCE）, an essential physical phenomenon of semiconductors when the size becomes comparable to the exciton Bohr radius, typically results in quite different physical properties of low-dimensional materials from their bulk counterparts and can be exploited to enhance the device performance in various optoelectronic applications. Here, taking Cs Pb Br3 as an example, we reported QCE in all-inorganic halide perovskite in two-dimensional（2D） nanoplates. Blue shifts in optical absorption and photoluminescence spectra were found to be stronger in thinner nanoplates than that in thicker nanoplates, whose thickness lowered below -7 nm. The exciton binding energy results showed similar trend as that obtained for the optical absorption and photoluminescence. Meanwile, the function of integrated intensity and full width at half maximum and temperature also showed similar results, further supporting our conclusions. The results displayed the QCE in all-inorganic halide perovskite nanoplates and helped to design the all-inorganic halide perovskites with desired optical properties.
