1·Slag, blowholes, and paint on unfused regions were observed at the welded junctions.
在焊接处看到了夹渣，气孔及未熔透区的油漆。
2·The result shows that there are no casting defects, such as shrinkages, blowholes, and slag inclusions and the quality of casting is steady.
生产结果表明，铸件没有气孔、夹砂、夹渣、收缩等铸造缺陷，铸件品质稳定。
3·Defects such as blowholes, cracks can be easily formed during welding process of nickel materials, which will severely affect the quality of the welding joint.
镍材焊接时易形成气孔和裂纹等缺陷，严重地影响焊接接头的质量。
4·Batch production shows there are no shrinkage cavity and porosity in casting, and no blowholes and sand inclusions on the top surface. The yield of the casting is 81%.
经批量生产验证，铸件内无缩孔、缩松缺陷，上表面无渣孔、气孔缺陷，工艺出品率81%。
5·It has been speculated that, as the blowholes evolved and migrated to the top of the head, the neural pathways serving sense of smell may have been nearly all sacrificed.
据推测，由于鲸鱼的气孔进化并最终移到了头部的正中，所以掌管嗅觉的神经纤维几乎全部不见了。
