We shall take a closer look at the concept of functional dependence . 我們將周密地考慮一下函數(shù)相關(guān)的概念。
To solve the equations these functional dependences must be determined by empirical or other means . 為解這些方程,必須用經(jīng)驗的或其他的方法來確定這些函數(shù)的相關(guān)性。
Based on functional dependence of relation algebra , the paper available expresses the coordination relation between primary and backup prection and it is fds which can generate directed basic loops and form optimal coordination sequences of protection setting , and accordingly achieve the optimal coordination of prections in the whole network . 本文充分運用關(guān)系代數(shù)中函數(shù)依賴的概念,有效地表達主后備保護配合關(guān)系? ?保護函數(shù)依賴集( fds ,即functionaldependencyset ,并用其自動生成網(wǎng)絡(luò)有向基本回路,形成保護整定最優(yōu)配合順序,從而達到全網(wǎng)的保護最優(yōu)配合。
