摘　　要：本文报道在横向16G超重作用下10只猕猴(Macaco mulatta)的实验,连续记录呼吸、心电和脑电活动.猕猴在超重作用过程中,开始呼吸频率反射性升高,然后下降,直至几乎完全被抑制;心率的变化是初始增加(70％的猴),接着逐渐下降,有时出现心率不齐,心传导阻滞等;记录的EEG主要为高幅δ波,接着波幅下降,同时伴有Q波或β波,直至脑电波消失.Ten rhesus monkeys (Macaco, mulatta) are exposed to 16G hypergravity force, the respiratory rate, EEG are continuously recorded. Under the action of 16G, the respiratory rate of all the monkeys increases first, then slowed down, and at the end of the centrifugation, the respiration almost ceased. The heart rate showed an initial increase (70% monkeys), then a gradual decrease, sometimes occurs arrhythmia, heart block etc. The brain waves appeared mainly to be the 'delta' waves with high amplitude and low frequency. Then the wave amplitude fell down gradually and accompanied by the appearance of 4-6 c/sec. 'theta' waves with small amplitude. Not until the EEG disappeared did stop the centrifugation.
