低频

Methods 15 healthy mongrel dogs were used to make models of intracranial hypertension by arranging latex sacculus epidurally.

有研究[1]发现在颅高压状态下，ICP的高频成分即脑脊液脉动有逐渐增大的趋势，但对于低频成分研究很少，国内亦未见报道。

The acceleration and sound pressure on the surface of seafloor are obtained.

建立了点声源作用下海底地震波的时域数值计算模型，利用该模型，对二维半无限空间简单海洋模型的低频点声源海底地震波问题进行了数值模拟，得到了海底表面处的加速度和声压值。

It is sea-level rising and falling of high-amplitude and low-frequency that caused sequence boundary signs of distinct characteristics and stable distributing, which included paleokarst surfaces, which included paleokarst surfaces, erosive boundary, exposure surfaces and regional freshwater diagenetic facies tracts.

对层序界面而言，由于克拉通上高幅低频的海平面升降变化，容易造成特征明显、分布稳定的层序界面标志，包括古岩溶面、冲刷侵蚀面、暴露面、区域性淡水成岩相带等。

The low frequency and large amplitude hydraulic shocker has a great prospect of being used in no-dig technique.

低频大振幅液压冲击器，以其优越的性能在非开挖施工方面拥有广阔的应用前景。

Now we maufactured products on scale, including: Semiconductor Laser / Low-frequency Treatment Instrument, Al Ga In P Semiconductor Laser Cure Instrument, Single-use Laser Head Cover, Laser Sitz Bath Instrument etc.

现规模生产半导体激光/低频治疗仪、铝镓铟磷半导体激光治疗仪、一次性使用导光头、激光坐浴机等系列产品。

F10 is one good auditory peg,but the desired effect is not so good with the original wire.It is bright and piercing on HF,it is dry on IF and it is in chaos on LF.It has no smoothy level and transfer,so the original wire let the quality of TF10 fall 3 levels.

F10是只好耳塞，但是原配线材的效果非常不理想，高频亮刺，中频干涩，低频团块，完全没有顺滑的过度和层次，一点不夸张的说，这条原配线让TF10连降3级。

Maybe you want to drop the lower frequencies out of a soprano?

或者你想要去掉女高音的那些低频？

The influence to woof performance of sound box from the variety of the box parameters is large.

音箱的箱体参数对音箱的低频特性影响很大，为了减小音箱设计与制作过程中的盲目性，有必要研制与开发一套相关的软件对音箱的低音特性进行仿真。

"Subaudible, low frequency sound and infrasound from wind turbines do not present a risk to human health" and "a major cause of concern about wind turbine sound is its fluctuating nature; some may find this sound annoying, a reaction that depends primarily on personal characteristics as opposed to the intensity of the sound level."

"低频声和风力发电机发出的声音都不会对人类健康造成伤害""人们关注风力发电机声音最主要的方面是它的波动性，有些人很讨厌这种声音。这种反应主要取决于每个人的性格原因，而不是声音的强弱度。"

Than low frequency sounds,most noise pollution damage is related to the intensity of the sound.

虽然高频声音比低频声音更加危险且恼人，大多数的噪音污染损害却与声音强度有关。

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。
