In addition to pic method, the numerical computation method is used as a compensation for the study of the characteristics of electron beam. the two methods are used separately to attain the trajectory of axially - emitted electron beam in diode region and drift region, and the trajectory of radially - emitted electron beam with axial, azimuthal, as well as compounded axial and azimuthal magnetic field. three two - dimensional codes and two three - dimensional codes have been made out to compute the trajectories
本文特點之一就是採用粒子模擬和數值計算相結合的方法進行模擬計算，分別得到了軸向發射條件下電子在二極體區域和漂移區的軌跡，徑向發射條件下電子在角向磁場、軸向磁場、角向和軸向復合磁場中電子的運動軌跡，分別編制了三個二維電子軌跡計算程序和兩個三維電子軌跡計算程序，最後將粒子模擬和數值計算得到的結果進行了對比，得到了較為滿意的結果。 -
The combination of statistical modelling, genetics, and developmental biology begs many questions, such as the patterns of genetic control over development, the duration of qtl effects, as well as what causes developmental trajectories to change or stop changing
函數作圖綜合了生物學機制的數學特性和性狀遺傳作圖的統計學特點，結合統計模型、遺傳學和發育生物學的函數作圖策略，力求解決諸如發育的遺傳控制模式、 qtl的持續效應以及引起發育過程中啟動和終止的遺傳機制等問題。 -
The simulated profiles of flow field, temperature and humidity of the air phase, as well as particulate phase, in the drying chamber were showed. the simulation also showed that a large - scale vortex was observed in upper part of the drying chamber because of the unstable process of flow field and particle trajectories
通過模型的求解，得到了乾燥室內氣體運動狀態，氣體溫度、濕度分佈，顆粒運動軌跡，顆粒沿運動軌跡質量變化，顆粒沿運動軌跡的溫度變化等各種動力學和熱力學參數分佈信息。 -
These controllers demonstrate effective performances by numerical simulations. the simulations also indicate that the system track the reference trajectories well under the control of trajectory track control laws. in the end, an experimental apparatus for tethered mass system is utilized to
數值模擬表明，線性二次型最優控制律對系統的面內和面外運動均具有良好的控制效果，在參考軌跡控制中系統能較好地追蹤參考軌跡。
