Pilots used a pacing tool called a tachistoscope that flashed images before their eyes at increasing speeds.

飞行员用一种叫做视速仪的仪器，它能在飞行员眼前快速地闪过敌机。

Using the reaction time as the indicator and presenting the stimuli ina tachistoscope, these experiments changed systemically the area and reflectance of the inducing fields.

本实验以被试的反应时为指标，用速示器呈现实验刺激，通过系统改变诱导区域的面积和反射率对主观轮廓知觉进行了研究。
