查询词典 ceramics

Machinable bioactive glass-ceramics containing mica and fluorapatite were prepared byhigh-temperature melting. The glass-ceramics were analyzed by means of X-ray diffractometry, scanning electron microscopy with energy dispersive spectrometer and Fourier transform infrared reflection spectrometry. The bending strength, hardness and fracture toughness of the materials were measured.

Ceramics and soldering iron. With white and blue porcelain and powder colors, Wu created the nonobjective half-length statue, bright and vivid in color. Through repeated application of symbols in Chinese traditional ceramics, the ornaments on the household wares were finally turned into a cultural symbol of extremely simplified human figures. That is how Wu handled the transformation from traditional to modern.

青花和粉彩的近乎抽象的陶瓷半身人像，被赋予鲜艳的色彩，传统陶瓷提炼的符号不断重复，从附着于器物用品的装饰转而成为极简的现代人形的文化符号特征，完成了现代与传统的对话，是颠覆也是重生。
