I want a rul. er.

我想要一把尺。子。

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.

Aiming at the linear time invariant system, a characteristic value was proposed and the prediction error of RUL was analyzed under some assumptions for system structure and hidden fault.

针对线性时不变系统构造了预测特征量，并分析了在一定的系统结构假设和故障假设下的剩余有效寿命预测误差。
