Abstract: Comparative experiments are conducted to analyze fatigue in this paper.The participants are randomly divided into two groups: the winedrinking group and the sleep deprivation group.In the former,the participants drink a certain amount of wine at regular intervals and then are tested.In the latter,they are forced to keep awake for 28 hours and then are tested at regular intervals.The equivalent length of awaking time can be obtained by comparing the performances of the two groups so as to measure the fatigue.
