使用电位滴定法，测定了水杨酸与铜离子生成的配合物条件稳定常数。分别采用半整数生成函数法、直接计算生成函数法和分段拟合生成函数法等3种方法对条件稳定常数进行计算。3种不同的生成函数方法测得的条件稳定常数之间存在一定的差异，这和计算过程及数据处理方法不同有关，由于直接计算方法简捷快速，推荐在这类稳定常数的测定工作中，使用直接计算生成函数法。

Three kinds of method of formation function, including semi-integer formation function, direct calculation formation function and piecewise fitting formation function, were applied to the determination of stability constants of complex of copper(Ⅱ) with salicylic acid, and the method of pH potential titration was used in this determination. There were some differences in the stability constant calculation results of three formation function methods because of the difference in the calculation procedure and data processing method. Direct calculation method was recommended for the determination of the stability constant because of its simple and fast.
