1) Perikymata
[,peri'kaimətə]
釉面横纹
1.
Perikymata were clearly shown on the entire crown surface,and the density of perikymata showed a gradual increase towards the cervix.
发现:禄丰古猿牙齿釉质表面有明显的釉面横纹结构;釉面横纹的密度向牙颈方向逐渐增大;观察记数了4枚牙齿的釉面横纹数,进而推算出牙冠的形成时间和年龄。
2) Cracks in the glaze
釉面裂纹
3) crackle
[英]['krækl] [美]['krækḷ]
(釉面)冰裂纹
4) surface transverse crack
表面横裂纹
1.
The surface transverse cracks on AISI304 strip produced by twin-roll strip casting were studied using optical microscopic observation and colored metallographic analysis,with consideration of the near rapid solidification characteristics of strip casting.
采用化学侵蚀和彩色金相等手段,对双辊薄带连铸304不锈钢铸带表面横裂纹的成因进行了研究,并结合双辊薄带连铸亚快速凝固的特点,对薄带表面横裂纹形成的原因进行了综合分析后认为,铸带表面横裂纹均为凝固时产生的高温热裂纹,熔池的液面波动、冷钢和铸辊的表面缺陷等因素导致的铸带表层凝固速度不一致是产生表面横裂纹的根本原因,而在随后的冷却和卷曲过程中,铸带受到各种形式的拉应力则是表面横裂纹得以扩展和加深的主要原因。
2.
The strengthening mechanism of low-alloy high strength steel and the cause of slab surface transverse crack formation were analyzed,the reasonable measures were adopted and AH60 quality slabs were produced,and afterwards AH60 plate was produced successfully.
分析了板坯表面横裂纹产生的原因及低合金高强度钢的强化机理,采用合理的工艺优化措施生产出无缺陷铸坯,特别是在控轧控冷前提下,利用细晶强化和相变强化,并结合缓冷工艺实现微合金的后期析出强化,成功开发出AH60微合金高强度钢板,达到设计强度要求。
3.
With the actual production,generated reason of surface transverse crack,slit and argon blister of wide slab have been analyzed.
结合实际生产,对宽厚板坯表面横裂纹、纵裂纹、氩气泡疤产生的原因进行了机理性分析。
5) weavecross-sectiondiagram
织纹横断面
6) lug type tread
横纹胎面花纹
补充资料:梨皮纹釉
梨皮纹釉 瓷器釉色名。早期结晶釉。又称“梨皮”。古代青瓷窑变产品。青釉釉料中含碱金属较低,并含少量磷酸或硅酸锌,入窑烧时由于窑变使釉面产生析晶。
