本文采用pH 电位滴定法测定磺基水杨酸铜络离子的稳定常数，得到了比较准确的结果（与文献值比较）。
It has been a good result by using PH-electrometric titration to determine stable constant about copper sulfo salicylic acid complex ion, in comparison with reference data.
其中优化手段主要包括预测策略的改进，采用理论公式计算值替代经验常数，通过实际数据回归修正公式系数等。
Optimization means include improvement of prediction strategy, theoretical formula calculation instead of empiric constants, and correction of formula factors with actual data regression.
为全面实现以上原则通过理论分析指出采用偏差输入将优于采用绝对值输入； 采用时间常数可变的时限电路将优于采用平方电路。
It proves that it is superior to use the "deviation input" to the "absolute-value input" and better to use time circuit with variable time constant than to use square circuit.
