magnitude of stresses
解釋

因此，織物在使用過程中所承受的摩擦壓力的類型和大小，將根據衣服和製品的類型而變化。 -
Results : 1 ) under the same condition of loading, the stress and displacement of mesial occlusal rest design was smaller than that of distal occlusal rest design in abutment teeth and soft tissue under the base, however, the magnitude in the soft tissue under base was bigger. 2 ) when a distributed vertical load was applied to the artificial tooth abutment teeth regions, the stress distribution was similar to that of concentrated load in the artifitial tooth, and stress magnitudes were higher. 3 ) under the condition tested, the mesial occlusal rest design caused the stresses that were more in line with the long axes of the abutment teeth than did the distal occlusal rest design
結果： 1 ）在同一加載條件下，近中（牙合）支托設計與遠中（牙合）支托設計相比，基牙及基托下軟組織的應力和位移值減小；基托下軟組織的應力和位移值大於基牙； 2 ）基牙及義齒整體加載時，各基牙應力分佈規律與人工牙加載相同，但應力值增大； 3 ）近中（牙合）支托設計使基牙受力更趨于軸向。 -
The main work of this paper was as fellows : ( 1 ) generalized the development of pre - stressed steel structure in our nation and abroad, and pointed out the main problem in practice ; ( 2 ) presented the mechanism of pre - stressed steel structure and revealed its applicable range ; ( 3 ) established the optimization design model for pre - stressed steel structure, which accounts for constraints on stresses and displacements of structure ; ( 4 ) brought forward the optimization design method, which combined linear programming and the principle of full restriction, through which we can obtain the magnitude of each time pre - stress and the optimized sections of each members of structure ; ( 5 ) analyzed the best times of pre - stress and pointed out that 2 ~ 3 times is preferable ; ( 6 ) conducted optimization design on large - space steel roof, horizontal parallel steel truss with local cables, horizontal parallel steel truss with global cable, and ultra - static steel truss, the result of which indicated that the multiple pre - stress structure is very economic ; ( 7 ) compared different schemes of cable placement for horizontal parallel steel truss, and the results showed that the local cable only unloaded the second girders, but had no response on the first girders and stomach poles, while global cable could unload the second girders and the stomach poles outside of turning point of cable, thus proving that global cable is more economic than local - cable
本文的主要工作是：對國內外預應力鋼結構的發展歷史及現狀作了綜述和總結，指出當前預應力鋼結構工程實踐中存在的主要問題；闡述了預應力鋼結構的受力機理，並指出預應力鋼結構的適用范圍和特點；在考慮結構應力和變位約束的條件下，建立預應力鋼結構優化設計模型；提出多次預應力鋼結構優化設計方法和步驟，採用線性規劃和滿約束準則相結合的優化方法，可優化設計出施加的每一級預應力的大小，並得到結構各部分的優化截面；對多次預應力最佳的施加次數作了分析，並建議以2 3次為宜；為驗證文中理論和方法，分別對大跨多次預應力鋼屋架、局部布索的水平平行弦鋼桁架、整體布索的水平平行弦鋼桁架和局部布索的超靜定鋼桁架等算例進行了優化設計，經濟效益明顯；對水平平行弦鋼桁架的幾種施加預應力的方案進行比較，對于局部布索，預應力只對下弦起到卸載作用，對上弦和腹桿基本不起作用；而整體布索預應力除對下弦卸載外，對索折點以外部分腹桿也起到卸載作用，經濟效益好於局部布索。 -
The total normal stresses arc then modified by satisfying the rigorous equilibrium conditions for the whole sliding body, resulting in an closed form expression for the required magnitude of anchoring force
再進行修正，使錨固后邊坡體滿足所有整體平衡條件，最後得到邊坡滿足給定安全系數要求的錨固力解析表達式。 -
Experimental results indicated that for the two reverse - bias stresses the degradation of the devices depended on magnitude and energy of the injected carriers. fc stress condition may speed up the degradation of devices and shorten the time of evaluating the devices life
在實驗中我們發現對這兩種應力，器件的退化與注入的熱載流子的數量以及能量有關， fc應力方法可以加速器件的退化，縮短評估器件壽命的時間。
