To define distance, limit, a delay operator, which is consistent to practical problems in waveform space.

在波形空间中定义了与实际问题相符合的距离，极限，延迟算子；

Using the fundamental operator family theory, they give some equivalent conditions for robust stability with respect to small delays for the kind of delay equations.

作者首先引入基本算子族的概念，然后应用它得到了几个小时滞鲁棒稳定性的等价条件。

In addition, the transfer of numerous facilities from one operator to another will cause inefficiencies and delay production, if a new plan must be prepared prior to operation of the facility by the new owner.
