Between different oxygen concentrations (mixed with nitrogen) ranging from 0 to 21% were passed over the corneas of six subjects for 5 min. The resulting corneal oxygen responses were measured by polarography. The averages of these responses were used to calculate a "relative oxygen uptake response" (ROUR) value for each oxygen percentage. Analysis of these ordered pairs revealed a curvilinear relation which was best described by a third order equation; marked linearity was demonstrated in the middle of the oxygen range. The use of this third order equation as a "standard" or "average" equivalent oxygen percentage (EOP) calibration equation is suggested.
在0%至21%（与氮气混合）的不同氧气浓度下，让其通过6名受试者的角膜，持续5分钟。通过极谱法测量由此产生的角膜氧气反应。这些反应的平均值用于计算每个氧气百分比的“相对氧气摄取反应”（ROUR）值。对这些有序对的分析揭示了一种曲线关系，这种关系用三阶方程描述最为合适；在氧气浓度范围的中间呈现出明显的线性关系。建议将此三阶方程用作“标准”或“平均”等效氧百分比（EOP）校准方程。
