Bochum 5. 15 pm on saturday afternoon : the final minute of the round 29 clash is almost over, as chinedu ede, who had come on for marko pantelic after 73 minutes, received a pass from gilberto and advances on the vfl bochum keeper drobny, before calmly finishing to make the final score 3 - 1 to hertha
波鴻，周六下午5點15分：第29輪比賽的終場哨聲即將吹響， 73分鐘后才替換馬爾科?潘特里奇上場的希內杜?埃德，接到吉爾伯托的傳球后晃過波鴻的門將德洛尼，冷靜將球射入網窩為赫塔將比分最終定格為3比1 ！Aiming at the high control performance of the mach number system in nf - 6 wind tunnel, we introduce the self - adapt control strategy based on bp neural network ( nn ), which it use adapt character of nn to control mach number of nf - 6 wind tunnel
針對nf - 6風洞對馬赫數控制系統提出的高要求，本文採用了一種基於bp神經網路的自適應控制方法，即：用神經網路自適應特性對風洞馬赫數進行控制。All the improvements included the modifications on the sound velocity, characteristic mach number and the mach number at the grid interface. several 2d flow fields which had shock, shear flow, rarefaction wave, or turbulent boundary layer and the combination of them were computed
該格式改進了聲速、特徵馬赫數的處理方式，對網格界面馬赫數進行了修正，並求解了含有脫體激波、斜激波、剪切流、膨脹扇、及湍流附面層等流動特徵的復雜流動。The two - dimensional axisymmetric subsonic - transonic - supersonic flow in an experimental arcjet thruster is simulated numerically using flux vector splitting method. the profiles of density, velocity, temperature, pressure and mach number can be obtained by the computation. the computation grid and some computed results are given here. the test equipment such as power supply system, ignition system, propellant supply system, arcjet thruster, thrust measuring device and vacuum system are introduced briefly. some working phenomena of the arcjet are observed and discussed. three different kinds of instability appeared in the process of the experiments. except some important parameters are measured, it is found that the operating stability of argon is better than that of nitrogen
