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,但其分佈形式沒有改變。
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. 通過分析高鉻鑄鐵件在凝固過程中應力的產生特點,得出高鉻鑄鐵件裂紋的產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更耐交變應力而不發生接頭缺陷,在針織時能保持彈力風格。
