摘要：

背景：闪光临界融合频率的测定容易受到主观因素和动机的影响。
目的：探讨CFF的变化与反应时间及正确率的关系，验证自行研制的数码管式闪光融合频率测试仪的实用性，并与EP403亮点闪烁仪进行比较。
方法：选取年龄在17~20岁，视力正常，无眼病的男性学员14名。利用数码管式闪光融合频率测试仪和EP403亮点闪烁仪检测受试者反应时间和正确率，并计算两者的关系，分析频率与反应时间、正确率的相关性；以及使用数码管式闪光融合频率测试仪和EP403亮点闪烁仪计算各受试者的闪光临界融合频率值，并分析两者结果的相关性。
结果与结论：频率值与正确率呈负相关，正确率越高，频率值越低；数码管式闪光融合频率测试仪的重测系数为0.739，P值为0.036；与EP403亮点闪烁仪测试结果差异不显著，说明数码管式闪光融合频率测试仪具有很好的实用性和可靠性。

Abstract:

BACKGROUND: Critical fuse frequency (CFF) determination is influenced by subjective and motive factors.
OBJECTIVE: To explore the relationship between the frequency and the reflect time and accuracy by the instruments of numeral critical fuse frequency (INCFF), and determine the CFF, compared with the instrument of shine flicker EP403. 
METHODS: A total of 14 male students, aged 17-20 years, with normal vision, were selected. The reflect time and accuracy were determined by INCFF and shine flicker EP403, and their relationship was calculated. The correlation of frequency with reflect time and accuracy was analyzed. CFF was calculated by two methods and analyzed.
RESULTS AND CONCLUSION: Negative relationship was between frequency and accuracy. The test-retest reliability of INCFF was 0.739 and P was 0.036; there was not different between INCFF and shine flicker EP403. INCFF displayed good practicability and reliability.
