查询词典 of the period

In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.

中国物流统计数据缺乏，客观上限制了对其周期规律的研究，本文选取社会物流总额作为测度指标，设计了一种人工序列，解决了统计数据过短问题；谱估计法从频域角度揭示客观事物的时间特性，在研究时间序列周期波动方面具有时域分析法所不具备的优势，作者采用谱估计法对中国物流发展周期进行测定，检验了指标序列平稳性，分析了截断点参数灵敏度，比较了6种不同滞后窗下周期值，并检验了所测得周期的显著性。

It is shown that the period of UW Vir is increasing rapidly dP/dt=+1.37×10^(-6 day/year while it undergoes a cyclic change with a period of 62.3 years.

结果表明该星的轨道周期在长期快速增加（dP/dt=+1.37×10^(-6)天／年）的同时也含有周期为62.3年的周期性变化。

A study in the Journal of Neuroscience finds that people with a particular version of a gene called Period 3 are better able to handle sleep deprivation because more of their brains get involved in counteracting the lack of zzz's.

发表在《神经科学杂志》上的一项研究发现，具有一种称为周期3（Period 3）特殊基因的人更容易应对睡眠剥夺，这是因为在对付睡眠缺乏的时候，他们大脑中更多的部位参与了进来。

Faculties granted for a fixed period of time, or a limited number of cases, cease when the period or number has been reached; but while awaiting their renewal the bishop, unless culpably negligent, may continue to use them provisionally.

院系给予一个固定的时间内，或者数量有限的情况下，何时终止期限或数量已经达到，但同时等待其续期主教，除非culpably疏忽，可继续使用他们暂时的。

The data of measured period of 1771 pulsars have been analyzed and detected, and 81 of them were influenced by the effect of lunisolar precession in their period measurement precision.

在对1771颗脉冲星测量周期的分析和检测中，有81颗脉冲星的测量周期在它们的测量精度范围内受到日月岁差效应的影响。

According to regionalizing indicators of average annual accumulated temperature above 20℃, average annual freezing index, precipitation in freezing period and average annual precipitation in nonfreezing period, the macro layer of the regionalization, China climatic regionalization for highway, were suggested through methods of cluster analysis, division based on indicator and layers superposing, which included 10 first-level regions and 24 second-level regions. It summarizes that climate of China affects highway in macro level.

利用多指标系统聚类分析、指标划分和图层叠置等方法，以累年年≥20℃积温、累年年冰冻指数、累年年非冰冻期降水量以及累年年冰冻期降水量为区划指标，对处于方案体系宏观层的中国公路气候区划进行了具体划分，提出了由10个一级区、22个二级区构成的两级区划方案，为了解中国气候对公路综合影响的异同性以及影响程度差异提供了一个平台。

Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF.

无论是在双极环状消融所有PV之前或之后，在体刺激颈迷走神经节过程中持续性房颤在所有犬均能轻易被诱导出，PV切除对心房肌的有效不应期或对胆碱的反应均没有影响，通过对高频的域下刺激发生快速或慢速反应来鉴定自主神经节，消融叠加于PV口部的自主神经节能抑制有效不应期的缩短、和刺激颈迷走神经诱发的房颤促进作用，而仅消融左或右侧PV口部的自主神经节却不能抑制房颤。

If learn to observe the means of oviposit period, oviposit period around adds defense line, with double insurance, even the method of 3 insurance, can prevent to fail more.

如学会观察排卵期的方法，在排卵期前后增加防线，用双保险、甚至三保险的方法，更可防止失败。

During this period, it is China's detection of forgeries to learn scientific theories and scientific methods of the initial formation period.
