2 . on simulating events ’ sequential - quality , we gave an idea of “ batch ” ; instead of conforming to events ’ physical time precisely , we consider about their logical sequence . we proposed an events simulation method based on the idea “ batch ” , considering spreading quality of events and time - mapping logic simulating methods 2 .對(duì)于繼電控制系統(tǒng)中事件時(shí)序的把握,我們沒有拘泥于其物理上的時(shí)間次序,而是從邏輯上來考慮事件的先后相繼關(guān)系,提出了邏輯清晰的“批”概念。
