低频

Research shows turning round vibration is the main vibration shape of system of direct empty cold construction, should consider fan of; of vibration shape coupling many a little bit the structural vibration that syntonic drive causes is answered lesser, movement of fan low frequency is more than the influence of high frequency movement to the structure to structural influence.

探究表明扭转振动是直接空冷结构体系的主要振型，应该考虑振型耦合；风机多点谐振激励引起的结构振动响应较小，风机低频运转对结构的影响大于高频运转对结构的影响。

Subsequent research by Tandy in other settings where naturally-occurring low frequency sound waves were found yielded similar results.

谭迪在其他情况下做过后续研究，自然产生的低频声波被发现可以产生类似的效果。

The main reason of inclined pipe fracture was low frequency stress fatigue failure at tempera- ture field.

斜管开 裂的主要原因是温度场下的低频应力疲劳破坏。

The present noise experiment therefore points to the enhancement of the tensile strain in the presence of channel narrowing, which in turn reduces the lattice mismatch.

在低频杂讯的实验中，对於通道宽度的缩减，相对应於应力的提高，也降低晶格长度不匹配的程度。

It is easy to generate this new directional filterbanks by tensor product of analysis filterbanks of DFT modulated filterbanks, and easy to extend the number of directional subbands.

通过DFT调制滤波器组的分析滤波组的张量积构造出新的方向滤波器组，这种新构造的方向滤波器组构造简单，方向数目扩展容易，并且能够有效保留图像的低频信息。

Applied DWT to R,G,B channel correspondingly, and used three low frequent coefficients to construct a 3-level tensor. Embedding the watermark into the core tensor, which got form Tucker decomposition, could diffuse the watermark into R,G,B.

首先对彩色图像R、G、B三通道进行小波变换，然后将获得的三个低频系数构成三阶张量，再经过Tucker分解后获得核心张量，通过在核心张量中嵌入水印信息使得水印信息扩散到原彩色图像的R、G、B三个分量中。

It is suggested that this is due to that two seperate processes are switched on by the prolonged low-frequency tetanization. While the inhibitory process does not intterupt the LTP production, it does defer the manifestation of LTP.

文中讨论认为这是由于较长的低频强直刺激启动了两个独立的过程，开始的抑制性过程并不妨碍LTP的启动，但可推迟LTP的表现。

With prolonged lowfrequency tetanization, a temporary inhibitory change was often observed immediately after the tetanic stimulation. But the evoked potentials began to recover more than ten minute later and finally exceeded the pre-tetanic level.

在较长的低频强直刺激下，往往先引出一抑制性变化，但十几分钟后反应逐渐恢复并将超过强直刺激前水平。

Thermal radiation ranges in frequency from infrared rays through visible light to ultraviolet rays.

热辐射的频率范围从低频的红外辐射到高频的紫外辐射。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
