  1. In this application, the lorentz force generated by the interaction between the current in the wire and the geomagnetic field produces an electro - dynamic drag leading to a fast orbital decay. in this paper, we make an intensive study of the process of de - orbiting using electro - dynamic tether system. the concrete work includes : firstly, i have studied the basic principle of how to generate the electro - dynamic drag, modeled via accuracy geomagnetism, made a concrete analysis of the de - orbiting duration, the magnitude and direction of electro - dynamic drag under the action of the dipole and accurate geomagnetic models, set up a counterbalance between electro - dynamic torque and gravity gradient torque, emulate the de - orbiting process of spacecraft, and compared the change of six orbital factors and the de - orbiting duration under the action of the dipole and accurate geomagnetic models

    本文對基於電動力纜繩的航天器離軌過程進行了深入研究,具體工作如下:首先,本文研究了電動力纜繩產生電動力拉力的基本原理,建立了精確地磁場模型;分別在偶極子模型和精確地磁場模型作用下,對電動力拉力的大小、方向、離軌時間及電動力纜繩傾角的大小進行了計算分析;建立了電動力力矩與纜繩系統重力梯度力矩的平衡關系;分析了電動力力矩為系統提供能量的原理;最後分別在偶極子地磁場模型和精確地磁場模型作用下,對受電動力纜繩作用的航天器的離軌過程進行模擬,分析了在不同精度地磁場模型下,航天器離軌過程中各軌道參數的變化情況,並比較了不同模型對離軌時間的影響。
  2. At the heart of slcad is a sophisticated three - dimensional engineering model. this model includes the terrain, the structures and all the wires. the model can be viewed in plan profile sheets. the slcad model is much more than just a picture or cad drawing since slcad understands the relationship between these elements. when you drag a structure off the current alignment slcad will update wire positions. the effects of this structure move will be instantly visible in the plan profile sheet view. in slcad you concentrate on designing your line instead of wasting your time drafting

    有時控制尺寸會有所調整,有時節點板設計會變化一下。傳統繪圖時,面對修改,面對審圖人員發現的錯誤,繪圖人員往往只能夠手工一筆一劃地修改dwg圖形,工作量非常大。雖然有自動成圖軟體的支持,但是對待修改圖的工作,依賴自動成圖軟體重新從頭再生成一遍圖形既麻煩又可能帶來其它意想不到的問題。
  3. If the ide is running in tabbed documents mode, select a tab and drag it below or above the current document tile

    如果ide正以「選項卡式文檔」模式運行,請選擇一個選項卡並將其拖動到當前平鋪文檔的下方或上方。
  4. You can drag the current statement indicator to another line to either skip or re - execute code

    可將當前語句指示器拖到另一行,以跳過或重新執行代碼。
  5. As you drag, the table displays its current dimensions

    拖動該表時,表格會顯示其當前尺寸。
  6. The following table shows the events that occur on the current target of a drag - and - drop operation

    下表顯示在拖放操作的當前目標上所發生的事件。
  7. Event is raised when the user drags the cursor out of the control or the user cancels the current drag - and - drop operation
