symmetric balance 中文意思是什麼
symmetric balance
解釋
對稱平衡-
Second, we discuss the influence of environmental referance potential temperture and thermal wind on mesoscale symmetric instability. we find the expression of disturbance stream function and criterion of symmetric instability by analytical method and conclude that change caused by environmental referance potential temperture with height and thermal wind make critical richardson number and disturbance critical half - wave length of symmetric instability larger, that is to say, they benefit the occurance of symmetric instability. third, we study nonlinear perturbation analysis of mesoscale vertical circulation and evolution equation by means of f - plane. non - hydrostatic balance and filiter model
第二，討論了環境位溫與熱成風因子對中尺度對稱不穩定的影響。運用解析的方法求出了擾動流函數的表達式和對稱不穩定的判據，發現環境參考位溫隨高度的變化與熱成風因子使得對稱不穩定臨界理查遜數及擾動的臨界半波長都變大，這有利於對稱不穩定的發生。第三，採用f平面、非靜力平衡、濾聲波模式，討論了中尺度垂直環流非線性攝動分析及演變方程。 -
For these reasons, we can apply the theory of the model reference self - adaptive control syetem design based on the theorem of balance point stabilization in the force system of asymmetric cylinder controlled by symmetric valve. the main idea of model reference self - adaptive controller is to make the self - adaptive control error incline to zero as time passed. the task to design adaptive controller is to find the control input that can make the output of the controlled system to follow that of the reference model
因此將基於平衡點穩定定理的模型參考自適應控制系統設計理論應用於閥控非對稱缸力系統中，其基本原理是使自適應控制誤差隨時間的推移而趨向于零，自適應控制器設計的目的是尋找使被控系統的輸出漸近一致的跟隨參考模型的輸出的控制輸入，以此來改善被控系統的性能。 -
The simulation models of balance traction transformer with two connection symbols are established. the operating state of transformer with symmetric and unsymmetric loads in secondary side is analyzed
摘要構建了兩種聯結平衡牽引變壓器的模擬模型，分析了二次側對稱和非對稱負載時變壓器的運行狀態。 -
After comparing superiority development under thermal wind balance to that under non - thermal wind, we find that non - thermal wind strengthens the superiority development of mesoscale symmetric disturbance. at the same time, the dynamic reasons for emerging non - thermal wind are noticed
比較了熱成風平衡及非熱成風時的中尺度對稱擾動的優勢發展后，發現非熱成風因子使得對稱擾動優勢發展得以加強，同時也導出了大尺度定常流非熱成風產生的動力原因。
