| water distribution ratio between inner and outer curved surfaces of strand | 铸坯内外弧面配水比 |
| water distribution ratio of inner to outer curved surface of strand | 铸坯内外弧面配水比 |
| water ratio | 含水率 |
| water soluble zinc ratio | 水溶锌率 |
| weight ratio | 重量比 |
| width-to-thickness aspect ratio | 宽厚比 (A width-to-thickness aspect ratio of 2.5 to 1.0 could be taken as the division between flat and long products. 宽厚比 2. 5比 1.0 可以作为扁平材和长材的分界线。) |
