In a trunked system, the switching station is known as the central controller. 在集群系統中，交換站通常被作為中央控制器。
This ability to combine multiple departments or agencies under one system while maintaining independent operations is the cornerstone of the trunking advantage. 這種在單一系統中融合多個(gè)部門(mén)或機構，同時(shí)保持其獨立運作的能力就是集群系統優(yōu)勢的基石。
Typical examples are the flows in the T-junction and the pressurizer in the cooling system of Pressurized Water Reactor. 典型的例子如在壓水反應堆核電廠(chǎng)主系統中的三通構件以及穩壓器內的波動(dòng)接管等構件中，射流與主流具有很大的溫差，這就會(huì )造成在非連續的射流與主流的混合過(guò)程中，構件承受著(zhù)巨大的熱沖擊，有可能使構件產(chǎn)生熱疲勞破壞。
