Furthermore, as the oscillating frequency of the cylinder approach the natural vortex shedding frequency, because of the phenomenon of resonance in the channel flow, and the heat transfer rate is enhanced more remarkably.

此外，当圆柱振动的频率接近流场的自然振动频率时，会与管道内的流体产生共振的现象，此现象能够大幅的增加流体的扰动，并且扰乱管道内的流场以及温度场，产生较佳的热传增益。

This structure has a natural frequency that is different from the buildings in this area. It is much more slender and has a lower frequency; which may have help it survive high accelerations.

这个构筑物的振动频率与它周边的建筑都不同，它很细长因而振动频率较低，这也许有助于它抵抗较高的加速度。

The intracerebroventricular injection of ACh increased the pain-evoked discharge frequency and shortened the latency of PEN,decreased the pain-evoked discharge frequency and prolongated of the inhibitory duration of PIN in LC of the normal rats.2）The intracerebroventricular injection of M-receptor agonist pilocarpine was similar to the effects of ACh.

侧脑室注入ACh能够使正常大鼠LC中痛兴奋神经元痛诱发放电频率增加、潜伏期缩短，痛抑制神经元痛诱发放电频率减少，诱发放电完全抑制时程延长，而后逐渐恢复；2）侧脑室注入毛果芸香碱能够产生与ACh相似的效应。

Study limitations include retrospective design, lack of data on the frequency and severity of every hematuria episode occurring both before and after HBO2 therapy, difficulty in quantitating effect on quality of life, and inability to determine whether the frequency of hematuria and the interval between consecutive hematuria episodes affected the therapeutic outcome.

研究的限制因素，包括本项研究为一回顾性的性质；高压氧治疗前后的血尿频率及严重程度等，皆未有资料以供利用；患者的生活品质无法量化；血尿的频率及发作的间隔期是否会对疗效造成影响，无法证实。

This paper mainly presents several methods in reducing the parasitic sidelobe level in phased arrays, and uses a method for randomizing the phase errors to improve DDS on the condition of a phase truncation.

DDS是参考时钟进行抽样、数字化，经过数字处理产生需要的频率，它的优异性能为频率合成的设计开辟了宽广的前景。

The frequency characteristics and SRs of OAG in a second-order linear systemwith fluctuating intrinsic frequency or randomizing damping coefficient by asymmetricdichotomous noise are investigated.

The size of the re-established social network is positively related to the obtained resource.

农民工社会网是一个互动频率紧凑的网络，网内互动频率紧凑关系的比重超过80％。

Based on the original damping coefficients formula, the improved Reynolds equation is presented and the damping coefficients formula include the frequency variable is recomputed. The relation with the damping coefficients and working frequency is obtained and the results are certified using the finite element analysis simulation. Moreover, the damping coefficients of perforated-hole film are obtained on the basis.

本文在推导原阻尼系数公式的基础上，提出了改进的雷诺方程，重新推导得到了包含频率信息的膜结构阻尼系数公式，指明了阻尼系数与工作频率之间的关系，并通过有限元仿真分析给与验证，同时在此基础上得到多孔方形膜结构的阻尼系数。

On some higher end reverbs you can see the decay split into 3 frequencies, low, medium, and high. With this kind of parameter control, you can have more control over how the different frequency ranges decay.

在高端的混响器中，你能发现decay被分开成为3个频率，低频、中频以及高频；对于这类的参数控制，你可以在不同的频率区域上设置更多的decay调整控制。

Namely in high-frequency unit use gradually incisive time resolution and lower frequency resolution, in order to moves the near observation signal quickly to change the part; In low frequency partially has the higher frequency resolution and the lower time resolution, in order to moves the far observation signal slowly to change partially, the wavelet this kind of signal analysing expression characteristic to analyzes the non- steady signal is extremely effective, suits the transient state anomaly very much which smuggles in the survey normal signal and demonstrates its ingredient, therefore by reputation for analysis signal microscope.

即在高频部分使用逐渐尖锐的时间分辨率和较低的频率分辨率，以便移近观察信号的快变部分；在低频部分具有较高的频率分辨率和较低的时间分辨率，以便移远观察信号的慢变部分，小波这种信号分析表示特征对分析非平稳信号是非常有效的，很适合于探测正常信号中夹带的瞬态反常现象并且展示其成分，所以被誉为分析信号的显微镜。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
