另外，慣性穩定性的作用以往不受重視，本文通過對西南低空急流左前方和高空偏北大風軸右後方的慣性穩定性和對稱穩定性的理論分析和實例計算，表明慣性穩定性在伴有高低空急流的暴雨中有重要意義，揭示了梅雨暴雨的一種新的高低空急流耦合機制：低空急流左前方慣性穩定度大值區的存在，有利於低層濕熱能量的積累，使低層傾斜對流的不穩定發展更多期望于條件性對稱不穩定或對流不穩定；高空偏北大風軸（西風急流）的存在，是其右後方（右側）出現對稱不穩定的有利條件，高空相對容易出現干對稱不穩定；慣性穩定性的作用，使低層的傾斜對流更偏向於垂直方向，有利於對流發展，使高層的傾斜對流更偏向於水平方向，有利於高層輻散。A simulation is carried on three swirling flow with different nonaxisymmetric tangential injection in a horizontal straight pipe to find if neglect their deflations whether they equate to axisymmetric module. a conclusion can be found that when nonaxiwymmetric conditions are occurred, there will be deflections near entrance that are different from axisymmetric condition, and these deflections will be erased on area far from entrance

計算結果表明，由彈簧質量模型算得的地下結構在地震作用下縱向振動和橫向振動產生的縱向和彎曲正應力及剪應力明顯高於由二維平面有限元算得的橫向平面內產生的正應力和剪應力，由此可見軸向應力和彎曲應力是地下結構抗震設計中不容忽視的因素。The previous discussion addressed the theory required to compute the relative phase shift between adjacent radiating elements in order to position the beam of an array - type antenna to a specific angle off of the antenna boresight axis
前面的討論中給出了計算使陣列天線的波束相對天線視軸線偏移一個給定角度所需的相鄰單元間相對相移的理論。If the reference element has a phase of zero, compute the phase applied to element five when the beam is scanned 40o above the boresight axis
如果參考單元的相位是零，計算第五單元當掃描視軸線以上40度的相位。Similarly, to position the beam below the boresight axis requires the use of a negative angle. this yields a negative and equation ( 7 - 4 ) again yields the applied phase of each element
同樣的，要使波束低於視軸線要求負的角度。增量就是負的，式（ 7 - 4 ）仍可用於計算每個單元的增量。But the traditional static design method is based on statics and seldom contains guidelines for incorporating the dynamic behavior of the moving belt. large safety factors are employed to accommodate most dynamic stresses in the belt. this can not only increase total cost but also give rise to system instability and higher dynamic stresses that can damage the belt, drums, idlers, bearings and other parts of the conveyor
在高速情況下，帶式輸送機存在的主要問題之一是起制動過程中輸送帶的動張力問題，而傳統的靜態設計方法將輸送帶視作剛體，並且在靜力學基礎上按靜止或勻速運行狀態對輸送機系統進行受力分析和參數設計，將動張力以一定系數計入，用加大安全系數方法提高設計可靠性，這不僅會使帶式輸送機的成本提高，還可能引發起制動過程中較大的輸送帶動應力及運行過程中的不穩定性，從而導致輸送帶接頭的失效及滾筒、托輥、軸承乃至其它部件的損壞。At first, configuration method of stabilization of los and survey of development of aoep in the world are summarized in this paper, and then principal of how movement of airplane can be isolated by a two - axis - platform is analyzed theoretically. requirements of stabilization of los to servo system are put forward. it provides the basis of theory for designing servo system
