EFFECT OF MODIFIED METHOD BASED ON RECOIL MOTION ON INTERIOR BALLISTIC PERFORMANCE OF ULTRALIGHT HIGH-LOW PRESSURE ARTILLERY

Effect of modified method based on recoil motion on interior ballistic performance of ultralight high-low pressure artillery

Light gun is of unique application prospect for its low body mass and projectile initial velocity.In order to solve the problem of calculation error caused by the large free recoil velocity of light artillery in traditional interior ballistic model, a more suitable internal ballistic model for ultralight artillery was proposed through the design an

Identifying genetic relationships among tarsier populations in the islands of Bunaken National Park and mainland Sulawesi.

Eastern tarsiers (Tarsius tarsier complex) are small nocturnal primates endemic to Sulawesi Island and small adjacent islands of Indonesia.In 2004, the hybrid biogeography hypothesis predicted this species complex might contain 16 or more taxa, each corresponding to a region of endemism, based on: 1) geological evidence of the development of the ar
