polar current 中文意思是什麼
polar current
解釋
極地氣流-
Mems ( micro electromechanical system ) has become one of the most rapidly development technologies. along with the rapid development of mems techniques, capacitive sensor is used widely whose capacitance changes small, which has put forward the new request to the measurement technique. the common measure for capacitance measurement is that convert capacitance to voltage, electric current or frequency. the area of polar plate of the capacitor becomes smaller and smaller, and the total capacitance of micro capacitive sensor is usually several pico farad only. as a result, its change amount is smaller
Mems （ microelectromechanicalsystem ）近年來發展最快的技術之一，隨著mems技術的快速發展，電容式加速度計的電容變化變化量越來越小，對檢測技術提出了新的要求。在電容式傳感器中，常用電容檢測電路是將其轉換為電壓、電流或者頻率信號。目前的微型電容傳感器的極板面積變得越來越小，電容總量只有幾個pf ，變化量就更小。 -
The anomalous fac pair creates a transient dusk - dawn electric field over the polar cap, tailing behind the original region current and drifting towards the night side until it falls into oblivion

In the meantime, the new region current keeps increasing and expanding towards the night and equator side, and it eventually replaces the original region current, so the polar cap returns to a state as original with a dawn - dusk electric field
與此同時，新生的區電流不斷增強並向夜側和赤道方向延伸，最終取代原區電流，相應極蓋區又恢復到原來的晨昏電場狀態。 -
First of all, we bring forward the basic project of tadil, which adapts to combined operations. it is suggested to use tdma ( the abbreviation of time division multiple access ) as the working pattern and utilize the concept of mobile ad hoc network to construct the data link network. aiming at the impact of time delay on data link and the characteristic of cooperative combat under the command of director aircraft, this thesis applies a kind of kalman filtering algorithm in polar coordinates to compensate the error of time delay, and then does the transformation of target motion parameters to obtain the current information of target
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。 -
