Digintel mechanics refers to the mechanics studies that would govern the scientific rules for the digintel era,with digintel abbreviates the combination of digital and intelligence.Digintel mechanics is defined herein as the exploration for the mechanisms concerning the interactions,both within and between,physical space,cyber space and cognition space,and as the revelation of causa-tion or/and correlation laws.Eight basic scientific issues concerning digintel mechanics are listed.At-tention is then focused on 7 routes of methodologies confined in the X-4 tetrahedron.Five research thrusts suitable for the preliminary development of digintel mechanics are enumerated,they are digin-tel mechanics formalism,mechanics of intelligent flexors,convergent digintel computation,cross-scale mechanics,and mechanics for embodied intelligence.
