More recently, the perovskite manganite compounds, la1 - xsrxmno3 have been used as the cathode of the solid oxide fuel cell ( sofc ) because of their electro - ion conductivity properties. in manganite perovskites, substitution of divalent ions ( alkaline earth metals viz
近幾年來， la _ （ 1 - x ） sr _ xmno _ 3這類鈣鈦礦型結構的氧化物材料因為其具有混合電子-離子導電特性而被廣泛的應用於固體氧化物燃料電池陰極材料。 -
In manganite perovskites, substitution of divalent ions ( alkaline earth metals viz. ca, sr, ba ) in the a sublattice, introduces mn4 + ions or holes into the system. it is generally considered that the concentration of holes is equal to the concentration of divalent cations because of the charge compensation by controlled valencies
在類鈣鈦礦型晶體結構中通過摻入二價堿土金屬（如ca ， sr ， ba ）可以在系統中產生mn ~ （ 4 + ）或氧空位，由價格補償的原理，理論上摻入的二價離子的濃度和氧空位的濃度相等。 -
By means of static and dynamic experiments, lots of research on the effect of micro - quantity heavy metal ions ( hmi ) removal by weakly basic anion exchange resins ( wbaer ) from drinking water ( dk ) with alkali metals, alkaline - earth metals and anions at high concentration, has been done
本文採用靜態和動態兩種試驗方法，對弱堿性陰離子交換樹脂在堿金屬、堿土金屬離子以及陰離子相對較高濃度的背景下去除飲用水中微量重金屬離子（以hg2 +為研究處理對象）的效果進行了大量試驗研究。 -
In a word, wbaer can effectively remove micro - quantity hmi from dk with alkali metals, alkaline - earth metals and anions at high concentration. on the basis of lots of regeneration experiments of wbaer ( d301g ), the best regeneration manner ( regurgitation regeneration ), the optimal regeneration agents ( h2so4 and naoh ) and the optimum operating parameters of regeneration are obtained
論文進而對d301g型弱堿性陰離子交換樹脂進行了再生試驗研究，確定了最佳再生方式（逆流再生） ，最佳再生劑（ h2so4和naoh ）以及酸液再生時的最佳濃度范圍（ 2 % 4 % ）和最佳流速范圍（ 3 4m / h ） ；並通過正交試驗確定了逆流再生過程中的最佳運行參數組合。
