The crowd of french soldiers fled with continually accelerating velocity , with all their energies directed to the attainment of their goal 法國的烏合之眾在逃跑過程中不斷加快逃跑速度,為了能逃到目的地而竭盡了全部力量。
The influence of double - push accelerated velocity , spin - rate regularity and unfolding fins on air rocket dispersion and the mechanism of decreasing of air rocket dispersion are also studied respectively 分別研究了雙推力加速度,轉(zhuǎn)速規(guī)律和尾翼延時張開,對地面火箭彈和航空火箭彈散布的影響,以及減小航空火箭彈散布的機理。
Now , the reported fgs can measure many physical parameters including temperature , strain , stress , displacement , pressure , torsional angle , twist moment ( moment of torque ) , accelerated velocity , current , voltage , magnetic field , frequency , density , coefficient of thermal expansion , trembling etc . some of the fiber grating sensing systems have been put into practical use 目前,已報道的光纖光柵傳感器可以檢測的物理量有:溫度、應(yīng)變、壓力、位移、壓強、扭角、扭矩(扭應(yīng)力) 、加速度、電流、電壓、磁場、頻率、濃度、熱膨脹系數(shù)、振動等,其中一部分光纖光柵傳感系統(tǒng)已經(jīng)實際應(yīng)用。
Using method of sumt and powell , the thesis carries out optimization design for air rocket with double - push accelerated velocity and spin - rate regularity , which dramatically decreases air rocket dispersion . in the end , some valuable conclusions are achieved for application 綜合利用雙推力加速度,轉(zhuǎn)速規(guī)律,同時采用內(nèi)點罰函數(shù)法和powell共軛方向法,對航空火箭彈的主要參數(shù)進行優(yōu)化設(shè)計,實現(xiàn)了大幅度減小航空火箭彈散布的目的,得到了一些有應(yīng)用價值的結(jié)論。
