生物钟

Due to relative stability of 'biological clock", one passing several time zones over median, inner biological clock will be out of step with environmental time, which is called "Jetlag.

由于"生物钟"的相对稳定性，跨子午线快速跨越若干个时区飞行，即可造成体内的"生物钟"与环境时间失去同步关系，称为"时差"。

Bear in mind that you'll have to take your biological clock into account.

记住，必须考虑到自己的生物钟。

This is because their normal routine is interrupted and the biological clock is disrupted.

这是因为他们的正常例行的中断和生物钟是破坏。

I m human being without biological clock.

我是一个没有生物钟的人。

Therefore will not have to worry about the destruction of their biological clock.

所以不需担心会破坏他们的生物钟。

The human body has a biological clock, so life must be the law.

人的身体有一个生物钟，所以生活要有规律。

This paper mainly studies the foundation of the models, the analysis of stability and the factors which affect the circadian oscillation.

本文主要就生物钟模型的建立、稳定性分析以及影响生物钟的主要因素这三个方面进行了研究。

These brain cells actas the body's internal clock. Some maintain a natural rhythm of roughly 24.5hours (thus a human kept in the dark will gradually fall out of synchronisationwith the day). Others entrain that rhythm to the light and dark cycles detectedby the eye.

这些脑细胞就像是人体内部的生物钟，有的具有大约24.5个小时的自然节律（因此一个人处于黑暗之中，渐渐地，他与白天的同步性会降低）；其他的脑细胞则可以根据眼睛感应的昼夜循环来维持这一生物钟。

For many years it was thought that neurons of the suprachiasmatic nucleus uniquely controlled circadian rhythmicity of peripheral tissues via neural and humoral signals. The cloning and characterization of mammalian clock genes revealed that they are expressed in a circadian manner throughout the body.

本篇综述，讨论了生物钟的分子基础，外周的生物钟，脉管系统以及心脏的昼夜节律基因表达，环境以及神经元对心血管功能的影响，时间生物学在心血管治疗中的应用以及生物钟对心血管疾病的暂时发病率的影响等问题。

Much is also known about the multiple clocks in our cells and the master clock in the brain that determines the circadian ebb and flow of hormones and chemicals that control temperature, heart rate, etc.

本书还告诉读者人类细胞中的多种生物钟和起主导作用的大脑生物钟决定了生理荷尔蒙、化学反应的昼夜变化，从而能够控制人类的体温、心脏跳动频率等等。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
