drag law 中文意思是什麼
drag law
解釋
阻力定律-
Abstract : a fast drag system is designed to simulate the law of speedvariations of a certain power system engine in the process of its start by means of electric power drag and the theory of automatic control and through adopting a new type of electric machine and frequency - change techniques, thus enabling the system to achieve quick start, instantaneous breakdown and accurate following of the electric machines speed variations curve set in advance at will
文摘:運用電力拖動與自控理論，採用新型電機及變頻技術，設計一種快速拖動系統藉以模擬某動力系統發動機啟動過程轉速變化的規律，使該系統能夠達到快速啟動，瞬間制動，精確跟隨事先設定的電機轉速變化曲線的目的。
