, 1996 利用激光气化铁氰化钾或亚铁氰化钾并利用飞行时间质谱检测方法对氰化钾团簇的形成机理进行了研究，结果发现：团簇正离子可归属为（Ｋ（ＫＣＮ）ｎ＾＋，ｎ＝０～３７，它们的幻数为ｎ＝４，１３，２２，３７；团族负离子可归属为（ＫＣＮ）ｎＣＮ）＾－，ｎ＝０～１３，它们的幻数为ｎ＝４，１３。这些幻数与氯化钠等碱金属卤化物团簇体系完全一致。这表明：它们的团簇结构应该是相同的，即１×３×３（ｎ＝４）３×３×３（ｎ＝

, 2013 本实用新型公布一种自动消除阴极结垢物装置，包括PLC控制器，继电器，钌铱钛电极，电流传感器、主回路、次回路等。PLC控制器检测到主回路电流减小时，断开主回路阴极继电器，闭合次回路继电器，将此阴极在次回路中改作阳极使用，实现了电极的正负转换，消除表面结垢物。几分钟后，断开次回路继电器，闭合主回路继电器，此电极继续作主回路阴极使用。用同样的方法，消除另一个阴极表面结垢物。阴极结垢物处理完成后，全部接入主回路，为主接驳盒供电。如此循环，保持阴极表面清洁 ...
