本文剖析了LabVIEW 數(shù)據(jù)流語言的特點，提供了其若干有效控制方法，指出LabVIEW 本身即可解決數(shù)據(jù)流控制上的變量沖突、響應(yīng)時序控制、初始狀態(tài)自適應(yīng)調(diào)整等問題并保證其通用性，而不必求助于其它代碼語言（如C 語言），這樣，既減輕了程序的復(fù)雜性，提高了效率，還豐富了LabVIEW 的應(yīng)用。文中以單選功能按鈕設(shè)計實例詳述了變量
沖突、響應(yīng)時序控制、初始狀態(tài)自適應(yīng)調(diào)整等問題的具體解決方案，在某型裝備測試系統(tǒng)的實際運行中驗證了該方法可行有效。

Abstract: The character of LabVIEW dataflow programming is analyzed and some methods
on the control of dataflow in LabVIEW are given. Problems such as variable conflict, time
responding sequence control and initial status self-adjustment are able to be settled out without sing other codes (e.g. C language)，so that the programming complexity is less and the efficiency s higher and the application of LabVIEW is more extensive. The example of the design of ingle-activated buttons is detailed showing how to solute the problems above concretely and the xperiment result running on some measurement systems proves the solution is feasible and eliable.
