Objective: To probe into the mechanism of Gusheng Pill, a traditional Chinese preparation, in the treatment of femoral head necrosis at the early stage after femoral neck fracture. 目的:探讨中药制剂骨生丸治疗股骨颈骨折后早期股骨头坏死的作用机制。
The dynamics model of multi-rigid-flexible bullet-fuze system was established, the transfer function of projectile-fuze system was derivated, the three-dimension overload of fuze and pill were simulated, as well as the three-dimension overload at the head of fuze under random pressure at projectile base. 建立了弹引多刚柔体动力学模型,推导了弹引系统传递函数,仿真了引信三维过载、弹丸质心三维过载,以及随机弹底压力下的引信头部三维随机过载。
