In this study,a necessary condition for quantitatively replacing metalic ions in displacement compleximetry is proposed:K′ R>K′ r;at the same time,the titration error formula of displacement compleximetry is established.
对置换络合滴定提出了定量置换出金属离子的必要条件：Ｋ′Ｒ＞Ｋ′ｒ；给出了置换络合滴定误差公式。
Based on substitution theorem,the virtual branch is replaced by a parameterized virtual power source.
基于置换定理,将虚拟支路用含参数的虚拟功率源置换,将虚拟支路的切除问题转化为虚拟支路两端点注入功率的增长问题。
