内折

试验证明了“隔墙现象”的存在，阐明了连铸坯内部缩孔不会被氧化而产生内折。

The test proves the existence of walling phenomenon and that the shrinkage cavities inside billet are not oxidized to form infoldings .

结果：①B组、C组高柱状上皮及内折乳头逐渐减少，扁平或立方状上皮逐渐增多。

Results : 1 High cylindrical epithelium and papillary became less and less , pavement epithelium or cubical epithelium became more and more step by step in group B and group C.
