drift period 中文意思是什麼
drift period
解釋
漂移周期-
The appropriate maximum stories and the appropriate maximum height of buildings are determined by using the various of control index, such as period, shear - compression ratio, allowable value of drift angle etc when earthquake fortification intensity is 8 degree
用各項控制指標，如周期、剪壓比、軸壓比、層間位移角等進行對比分析，給出在8度區該結構的最大可建造層數和最大適用高度。 -
But the influence trend of the maximum rolling angle and the rolling period was not so simple, it was because the influence of which embodied in the phase relationship of mass flow and the pressure drop across the tube. the d - partition method was developed to separate the test tube into four regions and the drift flow model was imported into the two phase region, based on which the solution of the response of the pressure drop of tested tube to the inlet mass flow perturbation can be obtained
在不搖擺和搖擺工況下，採用d分區法對實驗段進行分區，在兩相區採用漂移流模型對實驗段的壓降對入口流速擾動的響應進行了求解，給出了各區壓降響應的表達式，進而得到了在不搖擺和搖擺工況下，壓降與入口流速擾動之間的傳遞函數。 -
By examining on the rainstorm process happened during the period of july 4th - 5, 2003, the rationality of using textural feature as the whole decision - making model ' s foundation was successfully testified. furthermore, the improved cloud - drift wind retrieval t echnique which based on this decision - making model also showed a remarkable performance in analyzing a meso - scale weather system
通過對2003年7月4 ? 5日暴雨過程的試驗分析發現，使用紋理特徵作為整個分析決策模型的基礎是十分合理的，另外改進的基於紋理分類的雲跡風反演技術，由於精度的提高，使診斷水平有了很大的改善。
