Results It was shown that periodontal support loss results in increased stress of the terminal abutment tooth without sudden changes. 結果基牙牙周組織吸收導致支持組織應力增加，但其分布形式?jīng)]有改變。
The conclusion that its the thermal stress and phase -change stress that made the crack appear was made according to the forming str ess characters in high-chrome cast. 通過(guò)分析高鉻鑄鐵件在凝固過(guò)程中應力的產(chǎn)生特點(diǎn)，得出高鉻鑄鐵件裂紋的產(chǎn)生是熱應力和相變應力共同作用的結果。
This splicer in the first knot woven more resistant to stress instead of alternating joint occurrence of defects in knitted elastic can keep the style. 這種捻接結頭在機織時(shí)更耐交變應力而不發(fā)生接頭缺陷，在針織時(shí)能保持彈力風(fēng)格。
