非靜力中尺度數值模式mm5的四維變分資料同化系統進行的數值試驗結果表明: 「開關」變量保持與基態一致,所構造的切向線性模式能夠提供關于非線性模式擾動的一階近似,伴隨模式所計算的梯度值能夠為最小化過程提供較好的下降方向;郭氏降水參數化方案中對流每隔一個積分步的交替發生並不影響目標函數最小化的收斂速度; 「開關」變量的存在也不影響將風、溫度、氣壓和比濕結合起來同化對mm5降水預報準確性的提高。Subjects tested in the current " ability credential of tcafl " still emphasize the static knowledge accumulation, while abilities of dynamic transference, interpretation teaching organization are not embodied
目前的《漢語作為外語教學能力證書》的考試科目,側重點仍放在靜態的知識積累層面,而實際教學中的動態傳遞、闡釋、組織教學等能力的考核似乎沒有落腳點。Firstly mathematic model of the micro cantilever structure is established by elastic mechanics analysis, during which small - displacement and large - displacement are both discussed. also the direct current exiting voltage and alternating current exciting voltage are both discussed. then we investigate the bifurcations of the conditions which have been mentioned above
首先基於彈性力學的方法建立了微懸臂梁的動力學模型,包括微懸臂梁為精確撓度和近似撓度兩種系統,以及作用電壓為直流和交流的情況,並對各種情況進行了靜態分叉的分析。Topics covered include : static equilibrium, force resultants, support conditions, analysis of determinate planar structures ( beams, trusses, frames ), stresses and strains in structural elements, states of stress ( shear, bending, torsion ), statically indeterminate systems, displacements and deformations, introduction to matrix methods, elastic stability, and approximate methods
