II Realization of the zone charge recognition technology
A Building virtul prototyping model of the gun
Firing experiment of the gun may be dangerous and will use many human and material resources, it was advisable to build a virtual prototyping model of the gun by the many-body dynamics software ADAMS and then analyzed the dynamic characteristic of the gun.

Abstract: This paper propose a two-tiered network in which lower-power users communicate with one another through repeaters, which amplify signals and retransmit them, have limited capacity, and may interfere with one another if their transmitter frequencies are close and they share the same private-line tone.
