creep resistance of metal alloys. 增加金屬表面強度的放像去思考 因為creep是由表面開始發生為小裂縫 所以防止第一階段的發生----最有效 表面硬化處理---珠擊法(增加強度)--表面拋光(減少表面粗糙度)--奈米塗料或是表面塗佈強度較高的材料都可以 太久遠了----兩年多看過材導...
第一段是說要分離啥，第二段是說他用啥儀器(Thremo)，第三段是說他用啥牌子的column，第四段是elute的條件與配置溶液
實驗時以100cc含有製得之奈米TiO2濃度0.02g/cm3，使用0.1M的HCl或NaOH調整pH，在超音波水浴中攪拌30分鐘以期能精確控制PAA在溶液中的濃度。 PAA以溶液狀態加入。定量PAA溶於100cc水後再取出其中10cc加入TiO2溶液，然後...
