离子选择性电极测量法发展极为迅速。Gran提出标准加入法测量电位的图算法,应用于离子选择性电极电位测量,提高了测量精度。现有专门印制的Gran计算图纸,因它仅适用于20℃时的标准斜率,且要采用特制的多线束计算图,限制了它的应用和推广。赵藻藩提出以ΔE和Δ_(px)为纵轴的图算法;陈洪渊等提出多点增量三元计算图。此二 Ion selective electrode rapid development of measurement. Gran proposed a standard addition method of measuring the potential of the map algorithm used in ion selective electrode potential measurement to improve the measurement accuracy. There is currently a specially prepared Gran calculated drawing that limits its application and promotion because it only applies to the standard slope at 20 ° C and uses a special multi-beam calculation chart. Zhao Zhaofan proposed a graph with ΔE and Δ_ (px) as the vertical axis. Chen Hongyuan et al. Proposed a multi-point increment ternary calculation graph. This two
