Abstract：
Using a“preselection-register-operation for reselection”program,a selection systemof the Yunan big cloud chamber set used for cosmic ray reseach is projected andconstructed.A small on-line digital computation technigue is applied to the momentumselector of the system,and a special computation element is designed.According tothe deflection angle and momentum of a charged particle passing through the magniticfield,computation and logieal judgment can be done immediately for the track signal registered before.
