生理节奏的

The rhythm of physiological time is not modifiable except by interference with certain fundamental processes - Alexis Carrel.

生理时间的节奏是不可修改的，除非用某些根本性的方法进行干预——亚历克西斯·卡雷尔。

Each of us has our own normal circadian rhythm (natural daily rhythms of bodily functions).

每个人都有自己正常的生理节奏（身体日常运作的自然规律）。

"Scientist Steven Reppert, who led the research, said:""We have shown the need for the circadian clock for monarch butterfly migration ."""

负责这项研究的科学家Steven Reppert说："我们已经证实了生理节奏钟对于帝王蝶迁徙的重要性。"

This new study now shows that the insects use an body " circadian " clock as part of their sun compass.

一项最新研究表明它们事实上将自身的生理节奏钟与太阳结合起来判断方向。

A part of the body, such as the mass of muscle fibers of the sinoatrial node, that sets the pace or rhythm of physiological activity.

起搏点身体的一部分，如窦房结的肌肉组织纤维团，用来确定生理活动的速度或节奏

In spite of efforts to address the organization of the locomotor CPG in walking animals, little is known about the identity and function of the spinal interneuron cell types that contribute to these locomotor networks.

将遗传和电生理方法独特地结合起来所做的一项研究工作显示，这些细胞何以能够帮助确定脊索神经细胞的有节奏的活动。

Normally the two timers are in step, and the external cues tend to regularise the internal clocks to the more convenient 24 hour period.

这两部人体时钟在不受干扰时会使人体有一个25小时－－不错，是25小时的生理节奏，两部时钟系统在一般情况下步调是一致的，外界种种因素常常把内部时钟调节到更为合理的24小时一周期。

The first is hardwired: A master clock in the brain regulates a so-called circadian rhythm, which synchronizes activity patterns to the 24-hour day.

第一个是固定的：大脑中的主生物钟控制所谓的生理节奏，将人体活动与每天24小时对应。

"Modern society is chronically sleep deprived; a poll by the National Sleep Foundation in 2001 found that about a third of Americans report sleeping six hours or less during weeknights and 17% of people continue to do so through the weekend," Helen Burgess, PhD, lead investigator, told Medscape.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
