周期

In order to investigate the light cycle on the basis energy expenditure of tree sparrows and the effects of gonadal weight, we domesticated tree sparrow with temperature 25℃, three kinds of photoperiod in the climate box for four weeks, and then measured tree sparrows body weight, basal metabolic rate, as well as gonadal organ's fresh and dry weights.

中文摘要：为探讨光周期对麻雀基础能耗和性腺重量的影响，对25℃和三种不同光周期的麻雀进行4周人工气候箱驯化后，我们分别比较了雌和雄麻雀的体重、个体 BMR 和性腺的鲜重和干重。

In a series of papers by Barsky and Miron, Miron, and Beaulieu and Miron, the authors found that the seasonal cycle displays similar characteristics to the business cycle in the United States and internationally.

在Barsky与Miron、Miron与Beaulieu和 Miron的一系列著作中，作者们发现在美国和国际上季节周期对商业周期表现为类似的特征。

Then based of it, we combine the log periodic antenna with the biconical as a broadband assembled antenna.

然后在此研究基础上对三角天线进行研究分析，并将对数周期天线与之组合设计制造出一副组合式宽带天线，用于展宽对数周期天线的频带宽度。

And quasi-periodic and chaotic motion can bifurcate from periodic motion when parameters of the system are changed.

而在系统参数变化时，又由周期分叉形成了准周期和混沌。

Finally, by using a topological global existence result, we give the global existence of bifurcated periodic solutions and it is found that the system exists always a nonconstant periodic solution after the second critical value of the delay.

通过使用一个拓扑的全局存在性结果，还给出了分支周期解的全局存在性。结果表明在时滞的第二个临界值以后，系统总是存在一个非常数周期解。

When the mixing strength is large enough we find that theoscillation period of the intrinsic biquadratic term is equal to half of that for thebilinear term.

当s-d混合作用强度足够大时双二次耦合强度的振荡周期是双线性项振荡周期的一半。

This paper presents the configuration,design principal and performance of a blowdown short duration turbine test rig newly built by Institute of Engineering Thermophysics of Chinese Academy of Sciences.

本文介绍了中国科学院工程热物理研究所最新建成的暂冲式短周期涡轮实验台的装置结构和关键设备的研制原理及性能，描述了短周期涡轮实验过程、实验台的控制系统和测试系统，展示了本实验台的部分标志性实验结果。

On the other hand, the world has gone into an era of knowledge economy, the manufacture technology of the automobile industry in the world is much more than design and production and should include its whole life period or periods from market investigation, development and amelioration, manufacturing, distribution, after-sales service, breaking-down and reclamation to new cycles.

一是我国加入WTO后，国产汽车要应对全球化的挑战；二是进入知识经济时代，世界汽车工业的制造技术应考虑和操作的不再止于产品的设计与生产，而应包括从市场调查、产品开发和改进、制造加工、销售、售后服务，到产品报废、解体、回收，再到循环使用、循环利用的产品整个生命周期和多个生命周期。

The great bulge in the middle represents areas where you are, well, average.

在一个周期末端是祸，而在另一个周期末端则是福。

Methods MTT assay was used to determine the proliferation inhibition by cantharidin to A549 cell. FACS can were applied to detect the change of cell cycle.

采用MTT法检测斑蝥素对A549细胞增殖的抑制作用；流式细胞仪分析A549细胞周期及斑蝥素对细胞周期的影响。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
