  1. With the development of space exploration projects, the atrophy and decreased function in antigravity skeletal muscles are one of major problems that need to be solved for the prolonged space flight. to understand the features of decreased contractile function and increased fatigability in unloaded hindlimb skeletal muscles will help to develop effective countermeasures during space flight, and contribute to the prevention and treatment of skeletal muscle atrophy in long - term bed - rest patients

    隨著載人天活動的發展,天飛行時間越來越長,抗重力肌廢用萎縮引起的強直收縮疲勞增加,使天員運動易疲勞的感覺更加明顯,了飛行時間和工作效率,在應急逃生時肌肉發生損傷的可能增大,且影響返回地面重力環境后的再應能力。
  2. The problem is then fed to a nonlinear programming routine to solve for all parameters. the flight dynamics model with yawing motion of uh - 60a is given, scale factors of state variables and control variables are applied based on the consideration of algorithm convergence. then, the optimization of trajectories is expressed as optimal control problem with a performance index constrained by helicopter performance limits, faa regulation and so on

    首先,建立帶偏運動的直升機點質量模型,然後對狀態變量和控變量進行無量綱處理,因為狀態變量和控變量量值相差較大,這使得優化演算法收斂效果變差,所以需要選擇當的縮放因子,最後把直升機單臺發動機停車后的飛行軌跡表示成一個最優控問題,即在考慮直升機和far規范后,指定一個優化能指標,選擇合的路徑約束,然後再解最優控問題。
