  1. The envelop functions of ground motion for the small - moderate earthquakes in the near - source field are different with those of the larger earthquakes. there are not stationary part any more in the envelop function of these ground motions. after we analyze the characteristics of these envelope functions we take a exponent function instead the three part function

    近場的中小地震由於其在到震源的距離與震級方面的特殊性，其時程包絡函數的形狀與遠震、大震有很大的區別，在遠震、大震包絡函數中很常見的平穩段不再存在。
  2. It shows that the envelop function in the previous references is good only for wider well in the binding energy calculation

    這說明，前人選取的包絡函數，在計算雜質束縛能時，只在阱寬較大時適用。
  3. In the calculation of the photoionization cross - section, we find that with the changing of the photon energy, the variation scope of the photoionization cross - section of the envelop function in the previous references is much smaller than that in this paper

    本系列產品過流部件全部採用氟塑料合金製造，最突出的優點是具有自吸功能，是專為一些特殊的化工工藝工段需要在液面以上抽取原料而設計的。
  5. Finally, we make a specific analysis for our results, ani compare the result with that of the envelop function in the previous references

    最後對結果進行了詳細的討論，並將所得結果與包絡函數以x沙）取作一維有限深量子阱中波函數的乘積的兩種情況進行了比較。
  6. In the first part, following ref [ 27 ], the expression of the envelop function is obtained. then, considering the dismatch of effective mass between the well and the barrier, using the variational approach, we calculate the binding energy of hydrogenic impurity

    在第一部分，我們按照文獻[ 27 ]中的方法，得到了包絡函數的表達式，並利用變分法計算了類氫雜質的束縛能，其中考慮了阱壘中電子有效質量的失配性。
  7. We find, in the narrower wire, the binding energy calculated from the envelop function in this paper is better than that from the previous function ; in the wider wire, the binding energy of the three cases is closer because the quantum wire is close to gaas bulk

    我們發現:在窄阱時，由我們選取的包絡函數計算得到的束縛能比前人的結果要大一些;在阱寬較大時，由於量子線趨于gaa 、體材料，三種情況計算得到的束縛能幾乎重合。
  8. There were troubles in the continuity of the function and of its - derivative divided by band - mass on the boundary. in the theoretical calculation, the wave function is relative to the physical properties of the impurity greatly, the envelop function f ( x, y ) is expanded in terms of the one - dimensional linear harmonic oscillator function in this paper. it satisfies the continuity of the function and of its - derivative divided by the band - mass, so it improves the precision of the function and binding energy

    與以往工作不同的是，以前選用的x ， y方向電子的包絡函數f （ x ， y ）是一維有限深量子阱中波函數的乘積，在邊界上波函數的連續性和粒子流的守恆條件存在問題；而在理論計算中，波函數的選取與雜質的物理性質有密切關系，本文選取的電子的包絡函數是用一維線性諧振子的波函數展開而成的，在邊界上能夠同時滿足波函數的連續性及粒子流（ 1 / m ~ * ） f ' （ x ， y ）的守恆條件，從而使得波函數和束縛能的精確度得到了改進。
  9. And the use - case diagram, state diagram and class diagram are used in uml diagram, which describe the software model from its function, logic and static structure. and the main arithmetic is shown. during the detail design process the com component technology is applied to envelop the logical part, hence to update and improve the software ; the software system of evaluation of the virtual prototype of the high power tf co2 laser is developed

    本文採用面向對象的軟體工程方法對高功率橫流co _ 2激光器虛擬樣機評價軟體的需求進行了分析，並用uml中的用例圖、狀態圖和類圖分別從功能、邏輯和靜態結構三個方面對軟體模型進行了描述，提出了主要演算法，在詳細設計過程中應用com組件技術對其中邏輯部分進行封裝，以便於升級和改進，開發了高功率橫流co _ 2激光器的虛擬樣機評價的軟體系統。
