Rare Metals, EarlyView.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

随机变幅载荷下海水腐蚀疲劳裂纹扩展速率的断裂力学参量选择 [PDF]
, 1994 ＃ 本文就随机变幅载荷下疲劳裂纹扩展速率的断裂力学参量的选择进行了分析;并与压机变幅载荷下焊接接头海水腐蚀疲劳裂纹扩展试验数据进行了比较;由此认为采用△K_(rms) ;作为断裂学控制参量是可取的;并且认为用常幅循环加载下的焊接接头海水腐蚀疲劳裂纹扩展速率曲线代替以△K_(rms)为参量的随机变幅加载下的裂纹扩展速率曲线;以此来估算其海水腐蚀疲劳裂纹扩展寿命;在工程应用上不仅方便可行 ...
