This paper discusses how the Graphic Tracing Method is used to solve the problem of di mensions between procedures in terms of its principle, process and computer-aided calculation.

The offset curves are generated through image tracing,i.

The goal of this paper is to prove 3×3 lemma by diagram-chasing, and talk about exact property of the second row when the first row and the third row are exact.

Aiming at impoving the efficiency of the anti radar aircraft, we adopt the tracking method in our research on the guidance law of the aircraft.

A new algorithm for fuzzy clustering, tracking method is presented, which can overcome the difficulty of programming and reduce the workload of fuzzy clustring.

The equivalent fuzzy matrix was calculated with the tracking method and the serial number of the pulses was obtained,these have greater practical significance.
