shrinkage losses 中文意思是什麼
shrinkage losses
解釋
短期損失-
Considering the characteristics of internal force and structures of simply supported pc bridges, a novel automatically step - up method ( asum ), taking into account the influence of steel arrangement, steel ratio, stress losses of tendons and time - dependent concrete modulus, to analyze creep and shrinkage effects is presented. this method accepts all kinds of expressions of creep and shrinkage, and it is easy to calculate total stress, strain of concrete and steel and deflection of bridge at any time, the expected prediction accuracy will be obtained by further dividing the time - step within duration
首先，針對預應力混凝土簡支梁橋的受力特徵和構造特點，提出了徐變效應分析的全量形式自動遞進法，可考慮截面上鋼筋位置、配筋率、預應力鋼筋鬆弛、混凝土彈性模量隨時間變化等影響，且計算式可適用於任何形式的收縮、徐變特性表達式；建立的公式可方便地求解任意時刻混凝土、鋼筋的應力與應變和跨中梁體的豎向變形，計算精度可方便地通過計算時段的細分來控制，直至給出滿意的結果。 -
The paper indicates that the impact of nfpp upon state - owned forest regions is not only some direct economic losses caused by decreasing or forbidding deforestation, but also some indirect ones rendered by the shrinkage of wood processing industry, enterprise ' s disability to invest in projects of high productivity for lack of fund, and its difficulty in forming new economic growth, etc
