RUL abbr. 剩余使用寿命(Remaining Useful Life);荷重软化温度(Refractoriness Under Load)
- The RUL series can also be used in the long length cutting line.
对于长尺材剪料生产线亦可使用。 - Rul Safety #30: It is mainly the incompetent that donot like to show off their work.
那些不愿意展示自己工作的人大部分都是不称职的人。 - Now, this is in NO WAY a criticism of the rul, and I wish every success to those it helps.
但这绝对不是对这个原则的批评,而且我希望那些使用这个的都能成功。
