With the development of economy, environmental pollution especially the quality of atmosphere has become an urgent problem.Bio-energy is introduced first in this dissertation.Then the meaning of exploitation and Probiotics for Adults utilization of bio-energy is analyzed.In the end, central heating project in Linan Banqiao town is introduced to gla
The evasive maneuver strategy for a fighter against a NTSC to PAL Convertor medium-range air-to-air missile is crucial to improving aircraft survivability.In this paper, the deep deterministic policy gradient algorithm to train the agent to learn the evasive maneuver strategy is studied.The missile-aircraft engagement model parameters are the input
