首先自创“调制计算机显示法”制作视觉质量不佳的劣化汉字，后经识别实验的视觉检验，已论证此法的简便性和有效性。运用此法进行了两项劣化不同部位的识别实验，分别获得“劣化字的整合识别成绩与其劣化部位无关”的结果，并就此探讨了劣化条件下汉字的加工方式的整体性。 First of all, he invented the “Modulation Computer Display Method” to make degraded Chinese characters with poor visual quality. After the visual inspection of the recognition experiments, the simplicity and effectiveness of this method have been demonstrated. This method was used to identify two different degraded parts and obtain the results of “the result of integrated recognition of degraded words has nothing to do with the degraded parts”. And then, the integrity of processing methods of Chinese characters under deteriorating conditions was discussed.
