摘要：A simple portable flicker-value determining apparatus was deviced using transistors. In order to examine the accuracy of measurement by this apparatus, a calibrator was also made by using decatrous. Comparison of the flicker values determined by the new apparatus and those by the standard apparatus shows that the accidental error in each subject is 2-3 cycles. The apparatus was employed for prevention of heat stroke ; Having examined examination of the effects of cooling the head and adminisitration of aspartic acid salt on the flicker values, the cooling of the head was found more recuperative. for the stroke.
