The paper describes an attempt of shaking (i. e. decreasing inertness) the diurnal rhytnm of urine excretion of potassium in two test subjects under the conditions of 72-hour continuous wakefulness. It is concluded that continuous wakefulness exerts no shaking effect on the diurnal periodicity of the function. It is found that the rate of rearrangement of the diurnal rhythm of urine excretion of potassium after inversion of the diurnal cycle was lowest during sleep and immediately after it. It is emphasized that when evaluating the completeness of inversion of the diurnal rhythm of the function it is important to pay attention to the parameters recorded at night and morning hours.
该论文描述了在72小时持续清醒的条件下，对两名受试者尿液中钾排泄的昼夜节律进行“摇晃”（即降低惰性）的尝试。得出的结论是，持续清醒对该功能的昼夜周期性没有“摇晃”作用。研究发现，昼夜周期颠倒后，尿液中钾排泄的昼夜节律重新调整的速率在睡眠期间及刚结束后最低。强调在评估该功能昼夜节律颠倒的完整性时，关注夜间和早晨记录的参数很重要。
