Continuous recordings of respiratory gas exchanges of various laboratory endotherm vertebrate species, which have either a nocturnal (mouse, rat) or diurnal (monkey, quail, chicken) or equivocal (guinea-pig) maximal activity, kept under controlled environmental conditions of temperature, humidity, ventilation and provided with food and water ad libitum, show ultradian oscillations of mean and low frequencies (1 less than f less than 35 c.day-1). Harmonic analysis was used to assess periodic or random ultradian variations and to compute amplitudes and phases of these oscillations when these vertebrates were submitted to a light (100 lx) and dark circadian alteration (LD 12:12). Spectral analysis shows that a 100-lx continuous illumination or continuous darkness decreases circadian respiratory rhythms and increases these ultradian respiratory oscillations.
对各种实验室恒温脊椎动物物种的呼吸气体交换进行连续记录，这些物种具有夜行性（小鼠、大鼠）、昼行性（猴子、鹌鹑、鸡）或活动时间不明确（豚鼠）的最大活动模式，它们被置于温度、湿度、通风等可控环境条件下，并随意提供食物和水，结果显示平均和低频（1＜f＜35次/天）的超日振荡。当这些脊椎动物处于光照（100勒克斯）和黑暗的昼夜交替（LD 12:12）条件下时，采用谐波分析来评估周期性或随机性的超日变化，并计算这些振荡的幅度和相位。频谱分析表明，100勒克斯的连续光照或持续黑暗会降低昼夜呼吸节律，并增加这些超日呼吸振荡。
