When balanced red and green lights are alternated more than 20 times per second, the perceived flicker can be reduced by advancing the green flicker about 10 degrees of the red-green cycle. The required advance for least flicker is greatest at retinal illuminances around 1000 td and frequencies between 30 and 35 Hz. A model that predicts tuning at this frequency exists, but the tuning curve that is predicted is broader than that observed. A modified model is left for future publication. Meanwhile, other empirical properties of the advance required by green over red are described. In addition to the intensity dependence of this phase shift, we describe its dependence on intensity balance between red and green. Also, the intensity balance turns out to depend on the frequency being used, in contrast to the independence expected by Ives, the inventor of heterochromatic flicker photometry.
当红色和绿色平衡光每秒交替超过20次时，通过将绿色闪烁提前约10度的红绿周期，可以减少感知到的闪烁。在视网膜照度约为1000 td且频率在30至35 Hz之间时，实现最小闪烁所需的提前量最大。存在一个预测该频率调谐的模型，但预测的调谐曲线比观察到的更宽。一个改进的模型留待未来发表。同时，描述了绿色相对于红色所需提前量的其他经验性质。除了这种相移的强度依赖性外，我们还描述了它对红色和绿色之间强度平衡的依赖性。此外，强度平衡结果取决于所使用的频率，这与异色闪烁光度法的发明者艾夫斯所预期的独立性相反。
