本文結合空軍裝備部某「十五」預研課題，圍繞著戰術數據鏈、多機協同多目標攻擊、超機動攻擊、空對地攻擊這四個方面展開了一系列的研究工作:本文首先給出了適應三軍聯合作戰的戰術數據鏈系統的基本方案，建議採用時分多址的工作模式，並利用移動自組織網路的概念構建數據鏈網路，同時針對數據鏈傳輸信息的時間延遲特性和指揮機指揮下的多機協同作戰特點，應用一種極坐標系下的卡爾曼濾波演算法對該傳輸延遲誤差進行補償，並在此基礎上進行目標運動參數的轉換，以獲得目標相對于某無人機的當前運動信息，且利用模擬驗證了方法的有效性。During its operation, the rotor of the machine is always under the great suppression of centrifugal force. the surface of rotor is the most important part to enduring the forces and thermal energy. so the windings of rotor are in a common problem of happening one - point to earth short fault, two - point to earth short fault, or turn - to - turn short fault
汽輪發電機是一種高速隱極式同步電機，在其運行時，轉子受到強大的離心力的作用，而轉子表面是承受機械應力和發熱的最關鍵的部件，因此汽輪發電機轉子繞組容易發生一點接地、匝間短路和兩點接地短路故障。They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射，發現其中兩組數據顯示，輻射脈沖的周期隨時間縮短，而其強度則隨時間衰減至消失，這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉，放出的輻射因為重力紅移而衰減的情況相符。This model not only reckons in the effects of the space distribution and the connection pattern of the windings, the position of the short circuit point and the space harmonics of the gap magnetic field, but also takes into account the pole geometry, slot effects, saturation and eddy current in the rotor
該模型不僅能考慮繞組的分佈與聯接方式、故障的空間位置、氣隙磁場的空間諧波，還能細致地考慮磁極形狀、鐵芯的飽和和渦流等因素。分享友人
