摘要

进行了耐用性测试（RT）实验，以评估影响低离子强度水溶液中pH测量的各种主要因素的重要性，并确定主要因素之间存在相互作用。搅拌对pH值的测量有不利影响，因为它不仅会增加随机噪声，还会使测量值产生偏差。将温度控制在最接近的0.5°C就足以将测量值保持在0.01 pH。在精确的pH测量中，不能容忍添加NaNO3或KCl。还揭示了三个小的双因素相互作用。

Effect of Variables on pH Measurement in Acid-Rain-Like Solutions as Determined by Ruggedness Tests.

Ruggedness Test (RT) experiments were performed to assess the significance of the various main factors which affect pH measurements in low ionic strength aqueous solutions, as well as to establish the presence of interactions between the main factors. Stirring has an adverse effect on the measurement of pH, since it not only increases the random noise but also biases the measured value. Temperature control to the nearest 0.5 °C is sufficient for maintaining measurements accurate to 0.01 pH. Addition of NaNO₃ or KCl can not be tolerated in accurate pH measurements. Three small two-factor interactions were also revealed.
