Industrial asynchronus data link and physical layer . part 1 : physical interconnection and two - way alternate communication 工業(yè)異步數(shù)據(jù)鏈和物理層.第1部分:物理互連和雙路交替通信
By the method of dde , established information ' s two - way alternate between the kingview and vb , realized the automation in coke oven pushing management , the automatic recording and saving of the parameters 摘要利用dde方式,在組態(tài)王與vb之間建立信息雙向交換,實現(xiàn)對焦爐推焦管理的自動化和參數(shù)的自動記錄與存儲。
A condition arising when two or more data stations attempt to transmit at the same time over a shared channel , or when two data stations attempt to transmit at the same time in two - way alternate communication 當兩個或多個數(shù)據(jù)站想在同一時間通過共享信道發(fā)送數(shù)據(jù),或兩個數(shù)據(jù)站想在同一時間在雙向交替通信中發(fā)送數(shù)據(jù)時產(chǎn)生的一種狀態(tài)。
This paper investigates the closure property of sublogarithmic space - bounded 1 - inkdot alternating pushdown automata with only existential universal states , and shows , for example , that for any function l such that l loglogn and l o , the class of sets accepted by weakly strongly l space - bounded 1 - inkdot two - way alternating pushdown automata with only existential universal states is not closed under concatenation with regular sets , length - preserving homomorphism , and kleene closure Chandra kozen和stockmeyer提出了交替性alternation作為并行計算的一個理論模型。交替式alternating圖靈機是非確定性圖靈機的推廣,它的狀態(tài)集合被分為萬能狀態(tài)universal state和存在狀態(tài)existential state 。非確定性圖靈機可看作只有存在狀態(tài)的交替式圖靈機。
