English英语 term
crazing
All concrete products and many natural stones, under varying conditions of moisture and temperature, are frequently subject to crazing. A manufacturer careful in proportioning of designs and watchful of compaction techniques and curing methods will minimize the likelihood of crazing as a result of manufacturing causes. (Cast Stone Institute, Inc.)
Crazing is generally undesirable; however, certain glazes, referred to as crackle glazes, are specifically composed to develop a controlled form of crazing. (About.com)
Crazing occurs when the surface of a moulding is stretched beyond its limit, due to localised surface stresses being too high at some time during moulding, finishing, or use. (Performance Plastics Ltd)

银纹
银纹和裂纹极相似，不同之处在于裂纹中间是空的，银纹中间的空洞中有银纹质相连。银纹发展变粗，银纹质断裂，即成裂纹。银纹的出现和发展，使材料的机械性能迅速变差。塑料件成型后，在胶料流动的方向上出现银色的条纹。这是由于原料粒子干燥程度不够或者在注塑过程中胶料热稳定不强造成的。抗银纹性是塑料抵抗银纹出现和增长的能力，是塑料的重要性能指标之一。 (银纹, crazing)
银纹化是玻璃态高聚物所特有的一种现象。聚合物的银纹损伤是一个复杂的多层次阶段,从微观层次的分子链间缠结链段的重排、滑移、取向、解缠及断链,到细观层次的银纹引发,生长及断裂,直到后继的微裂纹的产生、扩展、串接最终导致材料整体破坏。 (Crazing)
