The status must be clearly identified at all times. This can be accomplished by a physical Segregation or electronically by the use of a Validated, computerized Materials management System.

任何时候状态都应清楚地标识，这可以通过物理隔离或者使用验证过的计算机物料管理系统来完成。

Here there is physical data segregation.

这种策略采用的是物理数据分离方法。

Owing to both physical and chemical properties of metal material, there are inevitably shrinkage cavities, porosity and segregation in ingots.

由于钢锭内部不可避免地存在偏析、疏松、缩孔及微裂纹等冶金缺陷。
